FitmentRear

Sizes10

Mud-phobic bar design actively evacuates packed soil and debris, keeping the tread biting instead of clogging in soft or muddy conditions

Linear flex zones allow the casing to wrap around rocks and obstacles when aired down — no sidewall stress, no cut-short trail days

Reinforced sidewall construction with advanced deflection rubber resists pinches, bruising, and splits in rough technical terrain

UTV-tuned tread compound delivers enhanced grip on wet rock and slick surfaces where generic compounds give up purchase

Steel-belted radial casing with Q-speed rating (up to 99 mph) means this tire behaves itself on paved connecting roads too

Stable, chunky tread blocks provide a confident foundation across rocky, uneven terrain regardless of your line choice

Best For

Trail Conqueror

This is the rider the KM3 was built for. If your weekends involve rock gardens, steep muddy climbs, and terrain that eats lesser tires alive, this tire won't flinch. Prioritizes real-world off-road performance over smooth pavement manners — and makes no apology for it.

Perfect Match

Ranch & Recreation Rider

You're mixing work and play — ranch chores, fire roads, the occasional trail adventure, and a stretch of highway to connect it all. The KM3 handles those pavement miles without drama while staying fully committed when the dirt starts. A solid all-conditions choice for the rider who needs one tire to do it all.

Great Match

Pavement-Primary Rider

If the majority of your miles are on paved or groomed surfaces with only occasional light trail exposure, the KM3's aggressive tread pattern is more than you need. You'll pay in road noise and slightly accelerated wear for capability you're not using. A hybrid all-terrain design would be a better match for your riding mix.

Frequently Asked

For most UTV applications, manufacturer specs typically land in the 12–15 psi range as a starting point. The KM3's linear flex zones let you drop to around 8–10 psi for technical trail sections without stressing the sidewall. Just make sure you air back up before hitting higher speeds on the road — running low pressure at highway pace generates heat and kills handling.

Better than most in its class. The mud-phobic bar layout is designed to shed packed soil continuously rather than letting the tread fill and go slick. The aggressive void ratio does real work in keeping channels clear. Extremely deep, liquid mud will challenge any tire, but the KM3 stays in the fight longer than a conventional tread.

It's more pavement-friendly than its looks suggest. The steel-belted radial construction and Q-rating give it real on-road stability, and wear is respectable for an aggressive mud-terrain design. You will notice more road noise than a hybrid or all-terrain tire. If pavement accounts for 70% or more of your riding, a less aggressive option is worth considering — but for a true mixed-use rider, the KM3 holds up fine.

Tread life is heavily terrain-dependent — abrasive rock chews through rubber faster than dirt trails, and riding style matters a lot. Mixed-use riders generally see somewhere in the 1,500–3,000 mile range before meaningful wear, with some getting past 4,000 miles in less punishing conditions. The steel-belted construction and quality compound work in your favor, but hard trail riding will always shorten the lifespan compared to mostly highway use.

Yes, and it's worth doing right. If you're running any highway miles, balancing makes a noticeable difference in ride quality, reduces vibration, and helps the tread wear more evenly. UTV tires are more forgiving than passenger car applications, but skipping the balance step is a shortcut that shows up over time. Standard balancing equipment handles UTV wheels without any issue.

The reinforced deflection design and tough sidewall rubber give the KM3 strong protection for a multi-purpose tire — it handles typical trail abuse well and resists the pinches and splits that end rides early. Purpose-built rock-crawling tires can go thicker and heavier in sidewall construction, but they come with real on-road compromises. The KM3 lands in a practical middle ground: serious protection without sacrificing everyday usability.
