Chalk test the tires, it's the best way to determine proper pressure.

I have deflators to take them down, and then I used the chak test to set the upper. Just note, the the TMPS might not like the chack test, but, is that a problem?

Will do the same when I get the new setup. Might be going with the GY with kevlar, waffaling on the BFG T/A KO. But going with these wheels I think.

Wheel Details - Discount Tire Direct

 

Toyo AT II's? P rated? I run 32-34 in my p rated ones the same size and seems to be the best balance...

 

Ok, need a little help, I know I'm missing something. I'm going to 15" rims, lets assume these Wheel Details - Discount Tire Direct They go on without modding the jeep. I know about the centric stuff.

Now, I was going to go 33x12.5R15, as this also meant I did not have to change anything on the JK. But noticed that the actual diameter is 32", the same as the stock tires. I was wondering, can I go with 35x12.5R15 without modding the jeep, I do have a 1.75 body lift right now?

Looking at the graph below, if the BFG 33 would work without a mod, then it seems to me the the 35 would as well, what am I missing here? Thanks in advance. I'm still looking at different brands, just using this as an example right now. Didn't format right

Tire -- Sect Width -- Tred Width -- Diam
BF GOODRICH TA/KM -- 10 -- -- 32.1 -- Stock.

BFG T/A KO 33X12.5R15 -- 12.4 -- 10 -- 32.7
BFG T/A KO 35X12.5R15 -- 12.7 -- 9.8 -- 34.7
GY MT/R KEVLAR 33X12.5R15 -- 12.5 -- 10 -- 32.8
GY MT/R KEVLAR 35X12.5R15 -- 12.5 -- 10.5 -- 34.8

 

I put 35 (true was 34") with flat flairs and I had to trim the rock rails and very little of the pinch seam. Not an exact answer but I hope that helps a little.

 

My pic is with 37's and a 2.5" lift.

 

Hmmm... The section width on the stock tire is 10, while all the rest are 12.something. Is that where the issue is? Does that mean the 33x12.5R15 will also have a bit of an issue?

 

Definitely on the front I'm not sure about the back. My wheels had 4.5" of back spacing.

 

I ran the 33" Duratracs (awesome tire) and did not have to trim a thing just some Spydertrax spacers but had to trim my Rub rails the pinch seam and the front air dam/splash guard and run spacers to not rub with m 35X12.50 17 Goodyear MTR w/Kevlar and I love these babies!

 

Thanks everyone... I guess I didn't notice the section size, going from 10 to 12.
