Frequently Asked Questions
Are AMS M1 Evil tires DOT approved or street legal?
No, AMS M1 Evil tires are NOT certified for highway use. While older production runs previously featured a "DOT" stamp on the sidewall, NHTSA enforcement of federal motor vehicle codes required AMS to update the branding. All current production models are explicitly marked NHS (Not for Highway Service) and are intended solely for off-highway off-road environments.
What is the difference between the 6-Ply and 8-Ply M1 Evil sizes?
The ply rating scales with the size of the tire to match machine weight and horsepower:
- 25" and 26" sizes: Feature a 6-Ply radial construction designed to keep weight down for mid-size UTVs and ATVs without sacrificing puncture resistance.
- 27" to 34" sizes: Step up to a heavy-duty 8-Ply radial construction built to handle heavier multi-passenger SXSs, rough rock trails, and aggressive cornering.
What terrain is the AMS M1 Evil tire best suited for?
The M1 Evil is an all-around, mixed-terrain specialist. Featuring a 1-inch non-directional tread depth, truck-style wrap-around shoulder lugs, and a tough natural rubber compound, it delivers maximum biting edge on hardpack, loose dirt, rocky trails, sand, and moderate mud.
How heavy are M1 Evil tires, and will I need a clutch kit?
Weights range from 25 lbs (25x8R12) up to 48 lbs (34x10R15). For stock sizes up to 28 inches, most machines run smoothly without clutch adjustments. If you are stepping up to 30-inch or larger tires (40+ lbs each), installing a aftermarket clutch kit is recommended to preserve belt life and maintain low-end responsiveness.
How does radial clamshell mold technology benefit ride quality?
Clamshell mold radial construction produces a more consistent, uniform round tire profile compared to traditional bias-ply tires. This reduces high-speed chatter on hardpack roads, ensures flat tread contact across the ground, and promotes long, even tread wear over hundreds of trail miles.
