Great Tires!!!!

Tried to order different tires at first, they were on backorder so talking to 4WD they referred me to these and I am glad they did. Just went through a jeep test track with different obstacles for topless day and they performed amazingly! Great traction from mud to rocks to wood. Don't think about it anymore, just order them. Alittle noise on hwy but what M/Ts aren't??

Great tire for both on and off road

Overall a good tire, little but pricey but worth the money. Good traction on and off road. Not overly loud on the street, still some noise but they are m/t tires

Asked by bubby from tulare ca. on

Bubby, the Pro Comp Tires 315/70R17, Xtreme MT2 is a metric sized tire. The measurements you're using is a flotation size. The 315 is the width of the tire in millimeters. The 70 is the aspect ratio which determines the height of the sidewall as a percentage of the width ( 70% of the 315mm). This tire comes out to a 34.4x12.4x17. Hope this helps!
