mike is correct. i just put dura trac. found some mud last night to drive in and i thought something was wrong because the TC never kicked in and it never held up or slowed down. it just clawed through the mud.

this was a odd feeling as i had 18" street tires before and the tc would kick as soon as i hit anything other then pavement haha

 

Mike, The Goodyear DuraTrac only comes in 275 and larger now!
