its a radial tire so its made for the road, but a lot of it depends on how religiously you measure your tire pressures, and make sure they are rotated...this is a total guess, but I'm saying you could probably get between 30-40 K...Im wouldnt quote that, but i know what i got on some pro comp radials and what i get on my swampers, and i would say those are pretty close to the pro comps
