Need help with tires

Just bought a set of factory rims (from a 2002 Wrangler sport) and want to put them on my 95 Wrangler. What Size tire would work? I've found 235/75/15 and 265/70/15 tires that I like. The jeep is all stock so there is no lift

Both should work, I run 235/75/15s on aulm. Cherokee Sport wheels 98 I think, they set out about 1" wider than the UGLY Stock wheels, They look like the old Crager SS wheels from the 60s and 70s.

What's better for the '02 8 inch wide wheel? I've seen that they recommend a 6.5 inch rim for the 235/75/15

they didn't change the bolt spacing till the jk's to my knowledge, i believe 2007 is when they changed it, from 1980 to 2006 it was 5x4.5 lug pattern, in 2007 they changed it to 5x5


and i'll have to double check, but i believe a 235/75/15 came stock on a ford bronco, all i have to do is go outside and look, and a ford bronco has a stock 8" wide rim

You should be able to go up to a 30x9.50 tire with no issues


BTW.
1987 to 2006 YJ & TJ Wrangler is 5x4.5
2007+ is 5x5
1986 and earlier CJ is 5x5.5

The lug pattern is the same 5 on 4.5 from '88 until '07 on YJ's, XJ's and TJ's , I know for sure I have factory wheels from each here and swap them out from time to time. There may be some earlier models that these will fit too, but this should help in your dilemma.
I would get either 235/75/15's or the 30x9.5x15's. The 30" tires look better to me but cost more

I know I'm Old School But, a 235 mm tire should be about 9.22" wide, in the old days Rule Of Thumb was the Rim should be no less than 80% of tire width, minimum rim for a 235 would be 7.376" or 7-3/8 in.

That's partly right, but it's more like 80% of the tread width. A 235mm tire is 9.25" section width (sidewall to sidewall), but the tread width is closer to 8". 80% of 8" is 6.5".

Oh! that must be by My 68 F150 came with 7.00X15" on 6.5" wheels and My 88 full size Bronco had 235/75/15s on 8" wheels, well now I know.

P.S., Do the Math.

Tire Specs Explained: Rim Width Range



Lea esta página en español
Rim Width Range
Because tires have flexible sidewalls, a single tire size will fit on a variety of rim widths. A tire's rim width range identifies the narrowest to the widest rim widths that the tire is designed to fit. The width of the rim will influence the width of the tire. A tire mounted on a narrow rim would be "narrower" than if the same size tire was mounted on a wide rim. NOTE: Because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width.
The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10".
For example: a tire in the P205/60R15 size is measured on a 6.0" wide wheel and this size tire has an approved rim width range from 5.5" to 7.5" wide. The tire has a section width of 8.23" (209mm) when mounted on a 6.0" wide wheel. If that tire were mounted on all of the rims within its range, the tire's approximate section width would change as follows:
Difference from
Measuring Rim Rim
Width Approximate Tire
Section Width 0.5" narrower 5.5" 8.03" Measuring Rim 6.0" 8.23" 0.5" wider 6.5" 8.43" 1.0" wider 7.0" 8.63" 1.5" wider 7.5" 8.83"
Because of the different wheel widths used in the above example, there is a 8/10" projected difference in tire section width when comparing a tire mounted on the narrowest rim to the widest rim within its range. This may affect fenderwell and frame clearances when selecting optional aftermarket wheel and tire packages.
Additionally, some vehicle manufacturers and tire companies have permitted rim widths that are not within the tire's original approved rim width range. For example: BMW has combined 235/40R17 sized tires on 17x7.5" rims (which are 0.5" less than the narrowest 8.0" wide rim listed for the size) on certain M3 models; and Chevrolet has combined P255/50R16 sized tires on optional 16x9.5" rims (which are 0.5" wider than the 9.0" wide rim now listed for the size) on certain Corvette models. While these applications have received the approval of the vehicle and tire manufacturers, staying within the approved rim width range helps assure that the tire's internal stresses are within its design parameters.
