Picked up my 2011 JK Unlimited Thursday Night. I am getting new tires soon (stock is 255/75/17), and am having some trouble digesting all this information. I drive 50 miles a day on the interstate so need them to have good road manners.

I have my choices narrowed down to Duratracs and MT/Rs in 33 or 35 depending on my lift/leveling kit choice. I am not so much worried about the size as I am the rim size and rating (E or D). Seems in the 33s and 35s Duratracs in the 16s (my preferred look) they only make E rating. Does this make that much of a difference?

If it does, that would leave me with MTR in 16 which is a D rating. Or, should I just go with a 17 inch rim and get the D rated duratracs? I like the more sidewall look of the 16, but is it worth going to a mud terrain tire over? Does 17 inch rims offer that much better ride quality?

Also, backspacing. I am eyeing the 16 inch Procomp 7069s (if I go with 16s), and they are 4" backspacing. Is that going to make these tires stick out too much? Seems most people have 4.5" backspacing.

Thanks

 

Go check with a professional tire man who makes his living installing off-road tires on trucks and Jeeps. Get his opinion. Seems you got a leg up on all the questions, so let him help you decide whats best for you and your Jeep.

I have the Procomps 7069 in 17", which is 4.75" backspace. Good looking wheel on the rig, hope they work out for you

 

I'm running Pirelli scorpion ATR's on 16" ProComp 7069's with 4" of backspace. The tread comes a hair past the factory flares. Tires have 50,000 tread-wear warranty and ride pretty nice on the road.

 

I've got 35" duratracs and the e rating doesn't bother me one bit. Running 28 psi on road and 14 off. Flex is very good, and the ride is just fine.

The mt/r k's are know to have balancing issues, and multiple members here have had a case of death wobble go away simply by going to a different tire.
