Today I decided to get the Hankook Dynapro ATM RF10's in size 285/70/17, they look alot better then the stock SRA's and give it a beefier stance. I will post up Pics later today. I have one question, can the spare tire holder hold a 285 size tireon the stock rim without any problems. The only thing I see is the tire crushes the rubber stopper on the back a little bit.

Yes, the stock tire carrier can hold a 33" tire with no problems, especially on a stock alloy wheel. I've got my 33" KM2's on heavy steel wheels and haven't had any issues.

I thought it woul dbe ok. what is a good tire pressure to run 285/70/17 at? It says max psi is 80.

I have the same size on the way, just a 16 inch wheel size.

They are actually bigger than the 305/70s on the jeep right now. By a half inch if that counts!

Ill probably run em at 28 or so, have to chalk test those things first.

I run my 33" KM2's at around 32psi and they seem to be wearing well. You might want to do a chalk test on yours to make sure. Find a nice flat, empty street or really big parking lot(1/4 mile should be good). Get some chalk and mark a stripe across the entire width of your tire(s). I did one front and one rear. Drive about a 1/4 mile in a straight line, then stop and look at the marks. If there is still chalk on the outer treads and none on the inner treads, then you're over-inflated. If there is still chalk on the inners and none on the outers, then you are under-inflated. If there is no chalk left at all, then you have the pressure set correct. I started high(38psi) and kept letting air out 2psi at a time until I got it right.

Thanks for the tip, I will try this tomorrow.

Do you have any pics? I'm looking into the same tires.
