Quick answer: AMP tires vs Atturo comes down to wheel size before it comes down to tread. AMP's Terrain Attack M/T A is a big-wheel tire, with 17 of its 27 sizes on 22-inch rims or larger and nothing in 16-inch, while Atturo's Trail Blade M/T covers 16, 17 and 18-inch metric and 33-inch sizes and cost $83 a tire less in a 35x12.50R20 at the same retailer in September 2026. On all-terrains the brands are within a dollar of each other, AMP carries the longer mileage warranties (60,000 on the Terrain Pro vs 50,000 on Atturo's best), and Atturo has roughly ten times the owner review data. Pick Atturo for a 33 or 35-inch overland build on stock-size wheels or for a heavy diesel; pick AMP for a 35 or 37 mud terrain on 24-inch or larger wheels, or for the longest treadwear warranty in the value tier.
The tire shop has both brands on the rack and the same story about each one. Three-ply sidewall. Self-cleaning tread. Great value. You are standing there with a 4Runner on 17s and a set of 33s in mind, and the AMP catalog the counter guy is flipping through does not have your size at all. That is the comparison in one moment, and it is the thing the spec-sheet shootouts skip.
AMP and Atturo sell the same promise: an aggressive off-road tire without the BFGoodrich or Toyo premium. Both deliver on it. But they built their catalogs for different trucks, and the winner of AMP tires vs Atturo depends less on tread design than on what is bolted to your hubs right now.
Two Brands, Two Very Different Catalogs
AMP is a house brand of The Wheel Group, the Ontario, California company that also owns Dirty Life, Mayhem, Cali Off Road, Body Armor 4x4 and Tuff Stuff Overland. TWG runs 20 distribution centers across the US and Canada and serves more than 8,000 dealer accounts, which is why AMP shows up at the shops that already stock TWG wheels. The lineup is four tires: Terrain Pro A/T P (daily driver, 60,000-mile warranty), Terrain Attack A/T A (adventure all-terrain, 40,000), Terrain Attack R/T (new hybrid, 50,000) and Terrain Attack M/T A (full mud terrain, no mileage number). The AMP tires complete guide goes tire by tire.
Atturo is independent. Michael Mathis founded it in 2009, runs it out of Illinois, and has said on record that the tires come from contract plants in Thailand, Taiwan and a limited number in China. The Trail Blade family is six off-road tires for trucks: A/T, ATS, X/T, M/T, MTS and Boss. Two of those lanes, the MTS for heavy trucks and the Boss for 37s and up, have no AMP equivalent. The Atturo Trail Blade lineup guide breaks down each one.
Neither brand owns a tire factory. AMP does not publish its sourcing, and TWG is a designer and distributor, not a manufacturer. Anyone who tells you either of these is "made in America" is guessing.
The Size Chart Is the Real AMP Tires vs Atturo Comparison
Go to amp-tires.com and count. The Terrain Attack M/T A lists 27 sizes. Two are on 17-inch wheels (35x12.50 and 37x12.50). Two are on 18s (LT285/65R18 and 35x12.50). Then six on 20s, six on 22s, six on 24s, four on 26s and a 37x13.50R28. No 16-inch size, no LT265/70R17, no LT285/70R17, no 33x12.50R17. If you drive a Tacoma, 4Runner, Wrangler, Gladiator, Bronco or Colorado on factory-diameter wheels and want an AMP mud terrain, your choices are a 35 or a 37, and both need a lift.
Now count Atturo. The Trail Blade M/T also lists 27 sizes, but six are 16-inch (LT235/85R16 through LT285/75R16), four are 17-inch including LT265/70R17 and 33x12.50R17, and eight are 18-inch. Eighteen of 27 listings land where the overland market actually lives, even after discounting the raised-white-letter duplicates. Atturo tops out at 22-inch wheels and 37 inches tall. AMP tops out at 28-inch wheels and 38 inches tall.
That is not a quality difference. It is a customer difference. AMP built the M/T A for the lifted half-ton on 22s and 24s that also bought Mayhem wheels, and covers that buyer better than Atturo does. Atturo built the Trail Blade M/T for the stock-wheel truck that wants a 33 or a 35 and a sidewall it can air down. The comparison articles ranking these two rarely mention it, and it decides the answer for more buyers than any tread pattern does.
The hybrids repeat the pattern. AMP's new Terrain Attack R/T lists 17 sizes across 17, 20, 22 and 24-inch wheels and skips 18 entirely, so a Ram 1500, F-150 or Silverado on factory 18s cannot buy one today. Atturo's Trail Blade X/T runs 17 through 26 inches in roughly 30 sizes, including LT285/70R17.
It cuts the other way on the Trail Blade Boss. The old story was a broad lineup of knife-blade mud tires from 15 to 24 inches. As of September 2026 Atturo lists seven sizes: 37x12.50R17, 40x13.50R17, 37x13.50R18, 38x14.50R20 and 40x14.50R20, plus two raised-white-letter versions. Nothing under 37 inches. The Boss is a big-tire specialty item now, and any comparison that hands Atturo the mud-terrain win because of the Boss is handing it to a tire most readers cannot fit.
Mud Terrain: AMP Terrain Attack M/T A vs Atturo Trail Blade M/T
Where the catalogs overlap, in 35x12.50R18, 35x12.50R20, 33x12.50R22 and the 37s, this is a close fight on paper. Both run 3-ply polyester sidewalls in LT sizes: AMP's construction spec reads 3P+2S+2N, Atturo lists full 3-ply sidewalls on every LT size. AMP's tread depth is 19/32 on most sizes and 21/32 on the biggest; Atturo's is 21/32 on most and 19 to 20/32 on a few. Both use staggered shoulders and sidewall lugs that bite when aired down. Neither carries a mileage warranty, which is normal for the category.
The owner data separates them more than the spec sheet does. On SimpleTire, the Atturo Trail Blade M/T sits at 4.3 stars across 197 reviews: 4.7 dry, 4.4 wet, 4.4 winter, 3.6 noise, 4.3 treadwear. The AMP M/T A sits at 4.5 stars across 23 reviews: 4.4 dry, 3.9 wet, 3.9 winter, 3.6 noise, 3.7 treadwear. Same noise score, which is what any mud terrain does at 70 mph. But AMP's wet, winter and treadwear numbers are lower, and the sample is small enough that two bad reviews move the average. One Silverado owner reported the truck "feels like it's going to shake itself apart" above 70, and a Ram forum thread has an owner who got roughly 10,000 miles out of a set. Atturo's complaint list is the familiar mud-terrain set: noise, uneven front wear, and wet cornering that needs respect.
Then price. On SimpleTire in September 2026, a 35x12.50R20 AMP M/T A was $329 and the same size Atturo Trail Blade M/T was $246. That is $83 a tire, $332 on a set of four, $415 with a matching spare, for two tires with the same ply count and within 2/32 of tread depth. Other retailers had the AMP closer to $280, so shop around, but Atturo was the cheaper mud tire at every retailer checked.
Verdict: Atturo, and not because of the Boss. The Trail Blade M/T covers more of the market, costs less where the two overlap, and has enough owner data behind it to trust the averages. The Trail Blade M/T overlanding review covers how it behaves aired down on rock and sand.
All-Terrain: Terrain Pro and A/T A vs Trail Blade A/T and ATS
This is where AMP tires vs Atturo gets even, and where the older comparison articles get one thing wrong.
The wrong thing first. The Atturo Trail Blade ATS is often credited with 3-ply sidewalls in LT sizes, which would make it tougher than AMP's 2-ply all-terrains. Atturo's own product page does not say that. The ATS lists 10 and 12-ply ratings (load range E and F), which describe load capacity, not sidewall plies. The full 3-ply sidewall language on Atturo's site belongs to the Trail Blade M/T, and independent reviewers of the ATS note the same thing: no 3-ply sidewall, and puncture resistance on rock to match. Both brands' all-terrains are 2-ply. Read the load range guide before assuming a "10-ply" tire has ten plies anywhere.
Now the comparison. AMP's Terrain Pro A/T P is the treadwear play: 60,000-mile warranty, 24 sizes from 17 to 24 inches, rock ejectors, chip-resistant compound, 14.4 to 15.8/32 of tread. It is the only tire here with a warranty north of 50,000. The catch is the review base: 10 reviews on SimpleTire at 4.0 stars. Nobody has put enough miles on enough sets to say whether the 60,000 is real.
AMP's Terrain Attack A/T A has the track record. 40,000-mile warranty, 14 sizes from 17 to 22 inches, 15.5/32 tread, and the best owner sub-scores of any AMP tire: 4.8 dry, 4.8 wet, 4.6 winter, 4.2 noise, 4.5 treadwear across 20 reviews. The complaints are balancing trouble and a stiff ride on lighter rigs in load range E, a fair note for a Tacoma or Wrangler owner.
Atturo answers with two tires. The Trail Blade A/T is the workhorse: 50,000-mile warranty, 26 sizes from 15 to 20 inches, mostly P-metric, 13 to 15/32 tread, and the three-peak mountain snowflake. It covers 15 and 16-inch wheels no AMP tire touches. The Trail Blade ATS is the one most overlanders will cross-shop against the A/T A: 50,000-mile warranty, 34 sizes from 16 to 26 inches, 11 to 17/32 tread depending on size, an all-terrain center with mud-terrain shoulder blocks, and the snowflake on tires built from 2025 forward. Owners rate it 4.8 stars across 64 reviews with a 4.4 noise score, which is quiet for a tire that looks like that. The drawback is the 2-ply casing on rock.
Price is a wash. In LT265/70R17, AMP A/T A was $206 and Atturo ATS was $205 at the same retailer, same week.
Verdict: split. If treadwear is the whole question, the Terrain Pro's 60,000 is the biggest number here, unverified. For the better-documented all-terrain, the A/T A and the ATS are peers, and the ATS has snow certification and 16-inch sizes on its side. Light rig in snow country, Atturo. Full-size truck that commutes, either.
Hybrid: Terrain Attack R/T vs Trail Blade X/T
AMP's Terrain Attack R/T is the newest tire in either lineup and arrives with a real spec: 50,000-mile warranty, stone ejectors, staggered sidewall, 14 to 19/32 of tread depending on size, load ranges from C to F. That warranty is 5,000 miles longer than the X/T's and unusual for a hybrid. What it does not have is history. Two reviews on SimpleTire, no forum threads with 50 replies, and no 18-inch sizes.
The Atturo Trail Blade X/T has been the value hybrid since Atturo put a treadwear warranty on it in 2018, now 45,000 miles. Around 30 sizes from 17 to 26 inches, 14 to 18/32 tread, load ratings to 4,080 pounds. It is the most-reviewed tire in this comparison at 394 reviews and 4.6 stars, which means its warts are well documented: balancing and high-speed vibration complaints, wet traction some owners call inconsistent, and noise that grows as the tread wears. Those are the same complaints every hybrid collects, and the sample is big enough that the 4.6 means something. The Falken Wildpeak vs Trail Blade X/T comparison puts it against a premium hybrid if that is the real decision.
Verdict: Atturo, on evidence. If the R/T builds a review base over the next year and adds 18s, revisit. Until then you are buying a warranty and a spec sheet.
Heavy Trucks: AMP Is Not Competing
The Atturo Trail Blade MTS is built for 3/4-ton and 1-ton trucks: 20 sizes from 16 to 26 inches, 17 to 22/32 tread, and 12-ply-rated sizes for the crew cab diesel that tows into the trailhead. A translation, because "12-ply" gets repeated as if there were twelve plies in the sidewall: 12 PR is load range F. Atturo describes the MTS casing as reinforced for weight and torque, and does not advertise a 3-ply sidewall on it the way it does on the M/T. You are buying load capacity and a stiffer, heat-tolerant carcass, not a thicker sidewall.
AMP's Terrain Attack M/T A reaches load range F on some larger sizes, with a maximum load of 3,860 pounds, which covers plenty of 2500-series trucks. But it is a general-purpose mud terrain that happens to come in F. If you tow and wheel a 2500 or 3500, the MTS is the tire here that was built for you.
The Warranty Fine Print Both Brands Hope You Skip
AMP's mileage numbers are longer. They are also mileage numbers, with everything that implies for a truck that leaves pavement. AMP requires installation within three months of purchase, rotation records, wear within 2/32 across all four tires, and no racing or commercial use. Staggered fitments get half the warranted miles on the rears. Atturo's is tighter: it excludes "any commercial, racing, or off-road applications," excludes wear caused by lifted or modified suspensions, and cuts staggered rears to 20,000 miles. Both prorate against list price and end at 60 months.
Read that Atturo clause again. Off-road applications. Lifted suspensions. If you are the reader of this site, the Atturo mileage warranty is not written for you, and AMP's rotation and 2/32 requirements will catch most overland rigs on the first claim anyway. Treat the numbers as a ranking of how confident each brand is in its compound, not as miles you are owed.

Who Should Buy Which
Buy Atturo if your truck is on 16, 17 or 18-inch wheels and you want a 33 or 35 with a 3-ply sidewall, because the Trail Blade M/T is the only mud terrain in this comparison that comes in your size. Buy Atturo if you tow with a 2500 or 3500 and wheel it, because the MTS is the only heavy-truck tire here. Buy Atturo for the hybrid with years of owner data behind it, or an all-terrain with a snowflake on the sidewall.
Buy AMP if you are on 24s, 26s or 28s and want a 35 or 37 mud terrain that comes in your wheel diameter, because Atturo's M/T stops at 22. Buy AMP if the longest treadwear warranty in the value tier is the point and you are willing to be an early data point on the Terrain Pro. Buy AMP if your shop already stocks TWG wheels and can have the tires on the truck Thursday, which matters when the trip leaves Friday.
Skip both and spend more if your trail time is mostly rock. Neither brand's all-terrain has a 3-ply sidewall, and the two mud terrains that do are loud enough on the highway to make you question the decision by the second tank of gas.
Two capable brands, built for different trucks. Check the size chart before you check the reviews, and the answer is usually sitting right there.
