Hi all -- I want to buy and restore this '88 Cherokee XJ Limited 4D 4WD 4.0L. The stock tire size of P225/75R15 is turning out to be a problem -- nobody makes that size anymore, at least not the good models of tire, like the Wrangler AT, Michelins, Yokos, etc. 15-inch wheels are too uncommon now, and Tire Rack had nothing.

So if I want to install good tires, what's a good size to target for wide market availability? Is a lift inevitable, or are there R17 tires that are the same overall size as stock? I guess I wouldn't mind a 1 or 2 inch lift, but I still have no idea what tire sizes I should shoot for. I don't really understand the geometry and what changes, or needs to change, when you increase the overall tire radius.

If I'm doing the math right, the stock tires are 28.3 inches tall. That's 15" for the wheels + (2 * (0.75 * 225 mm)) for the sidewalls. Converted to inches, those are 6.64" * 2, which is 13.28" + the 15" for the wheel, so 28.3" total.

I noticed that a 2021 Cherokee Trailhawk has 29.5" tires using the same math as above, with a tire size of P245/65R17. That size has full support from all the major brands. Would I be able to use that size wheel and tire on the XJ without any other mods? Will they rub against the wells?

Thanks.

Update: I figured out how to edit, and changed to ASCII above.

It looks like this site is having problems displaying non-ASCII Unicode characters, but I don't see a way to edit my post.

Where you see something like AE where the E is the Euro symbol, it's supposed to be an en dash. It's just a longer dash than a hyphen, used to separate phrases.

Where you see the A with a squiggly over it, it's supposed to be the multiplication symbol, the kind that looks like the letter x, but it's formatted for math, centered vertically.

I see many to choose from here from name brands, street/ at's ........ looks no problem'o?

Just go up one notch to a 235/75/R15 and there are quite a few more to choose from and the size difference is minimal.

235/75/15 or use a tire size converter app to find equivalent sizes.

With 1-2" of lift, 30x9.5x15 fits well.

Where is "here"? I was looking at Tire Rack and they said they had nothing in that size.

Did you try checking out other online shops such as 4WheelOnline?

I just looked at Tire Rack and it shows me 14 options in that size for my Colorado zip code. 10 options at Discount Tire's site.
There's 39 options on the 235/75R15 size I suggested at Tire Rack.

Have you checked Nitto tires?

Here's what I'm seeing below. Well, first let me say that when I put in the tire search by vehicle, Tire Rack tells me that it has zero tires in that size, BUT it's defaulting to a smaller size (195/75-15), and that turns out to be the problem initially. I didn't notice the size it was defaulting to before, which must be for a base model 1988 Cherokee they don't ask for the specific trim level or 2WD/4WD like they usually do for other vehicles. Then they offer an Optional Sizes tab for the vehicle, but those are 16 and 17 inch I have to go to Custom Size to put in the OEM size of 225/75-15.

When I look for your suggested size of 235/75-15 (searching strictly by size, not vehicle), I indeed get lots of results. Using a Fort Worth zip code, I get 40 total results, and 19 in the relevant category (On/Off-Road All-Terrain).

When I look for 225/75-15, which is the OEM size, I get only 11 total results, with three in the relevant category.

When I search on the vehicle and choose a custom size of 225/75-15, strangely I only get six total, not 11, with three in the relevant category (same three as above).

At Discount Tire, I get ten results for 225/75-15, but only two in the category: Goodyear Wrangler Trailrunner AT and Toyo Open Country A/T III, which are also in the three options at Tire Rack (Tire Rack's third option is the Pirelli Scorpion ATR).

No, not yet. I didn't know about them. The only potential hitch is that I want good all-around tires, premium performance, probably the "On/Off-Road All-Terrain" category, not the pure off-road, maximum traction kind. They need to be decent on the road too, since that's where they'll be most of the time.

Negative, I'll look. I haven't heard of them, thanks.

Thanks, I had never heard of a "tire size converter", and wouldn't have found that without the tip.
