ULAlum93 the 285 are still under the fender are do they stick out.?

twalton this is what i know: my jeep came with 32s. i had 33s installed and the tpms light came on(correct tire pressure). the tech recalibrated it as i stated above, and now the speedo is accurate(gps) and the tpms functioning properly. i'm satisfied. also, this dealer installs lifts, larger tires(35s) and a lot of offroad stuff under the warranty.

Ive found that chrysler says that cant do a lot of things that they really can.

My understanding is that what the tech did was recalibrate your speedometer, so that it's calculation of speed (distance covered per unit of time) based of the wheel spin will be accurate. A vehicle on 31" tires will travel less distance per rotation than a vehicle on 33" tires.

Your TPMS however will self-calibrate and automatically adjusts to new tire sizes. Pixie dust I think.

Oh ok cool thats a pretty good deal I think for 5. Can you elaborate a little more on the recalibration. I've never heard of a recalibartion for the TPMS..

How do u like those MT BAJA's? how much were they? they look really good. how do they ride and handle? Would u happen to know how much they weight per tire? Just curious. And you dont have any rub at full turn?

good choice on the 285 duratracs. thanks for the compliment on the bike rack. it is a yakima "spare time". holds 2 bikes and features an anti-sway cradle for each bike. it is simple, sturdy and easy to use . quadratec has them for $161.99.

Is this a stock setup? Any lift or spacers, any Rub?

So confirming a 275/70/17 will work with no rub or need for mods?

rics1997 Both are great choices. I love my 285's and the very slight rub didn't bother me really but I did end up getting wheel spacers in the end and even though 275's will not rub and won't need wheel spacers in the end a new wheel with better backspacing or wheel spacers gives you more choices and looks great because your tires don't hide as much under the fender

Can't decide 275/70/17 or 285/70/17

Need help deciding between a BFG AT 275/70/17 or a Goodyear Duratrac 285/70/17. These will be going on a 08 stock 4 door sahara auto with the 17" moab wheels. Which will be best with the stock set up with no mods. I want to stock as well. Thanks for the help
