235/75R15 wouldn’t fit on 15x8 wheels

So I recently discovered the “good” tires on my new to me ‘92 wrangler range from 9-20(!) years old. I attempted to get 235/75R15 Cooper Discoverer AT3’s installed today on my stock(?) 15x8 aluminum wheels and they simply wouldn’t fit. They were not wide enough for the 8” wide wheels despite the spec saying they will fit on a 6-8” wheel. Has anyone run into this? I’m scrambling to find alternate tires now since I don’t want to drive on these old tires. It’s got 30x9.5R15 tires on it now but wanted to step down a size since those rub when turning (I’m at stock height) and I’ve got a 2.5L with manual transmission. Any recommendations on a tire that will fit the 15x8 wheels and not rub?

BTW, this is what the two oldest tires look like on the inside. Clearly these were old spares that should never have been mounted.

the factory aluminum wheels are 15x7 and a 235 will fit a stock wheel

You never mentioned where your tires are rubbing, what is the offset on your wheels, new rims can correct the rubbing problem you have. Depending on where it is rubbing? A cheap fix to your rubbing problem, would be the use of something I don't recommend using, that is lift shackles. Now if you find some the are less than an inch longer then stock, I say slap them on there to give you more clearance. I use a shackle that is 5/8" of an inch longer than stock. Going higher than that is up to you, but I still say you should stay under an inch. Good luck with your project, hope you get it all figured out.

Hadn’t gotten as far as checking that, and I’ve only noticed it at full lock so far. I was going under the assumption these were stock YJ wheels and based on searching around here the 235s would fit good with no rubbing. Oh well, I’ve got 30x9.5R15 General Grabbers slated to go on Thursday now. I’ll re-asses any rubbing then.

General Grabber A/TX in 30x9.5R15 are on and working/looking good. New tires were definitely needed, it was a squirrelly few miles getting to the tire shop as this winter storm started to hit here this morning. On the plus side got to test out 4wd drive for the first time, works good. No problems driving home with the new tires.

Looks Good (y)

Those tires look good, especially on those wheels.

Did you mount 5 or just 4? I hope your spare wheel matches, if not just keep the cover on.

That's I nice Christmas present, I sure the YJ will return many pleasant trips.

I finally go around to having the plugs and coil packs replaced on my TJ yesterday, and now it drives like a new Jeep. Found horsepower I didn't know I was missing.

Wishing you and yours a very Merry Christmas.

Unfortunately the spare wheel is a basic steel one with some surface rust so I put the “best” tire on it, aka the only 9 year old one. I’ll treat it like a donut if it comes to needing it. If I had a matching spare rim I wouldn’t gotten a fifth grabber and rotated it in. Maybe I’ll stumble across a matching one one day.

Understand. Many time when someone changes wheels on a Jeep they only go for 4. That leaves the original wheel hanging on the back. They then hide it behind a tire cover. I have tried tire covers on my TJ twice and tosses both of them because they seem to gather all the debris the gets sucked up behind the square back.

When I bought my TJ in 2014 (it was 11 years old). it only had 4 center caps as the previous owner (we abbreviate it as PO, and OP is original poster, now called the discussion starter) had a bike rack that mounted to the spare tire mount behind the spare with a rod sticking through the hole of the wheel for the center cap. It took me a while to find one.

Here is a listing from a company that buys old wheels and refurbishes them.

There are a number on ebay a lot cheaper, but have rust, blemishes and list road rash and corrosion.

I just spent a chunk on my TJ this week as I had new spark plugs installed along with a new coil pack rail. In 2000 (IIRC) they replaced the distributer and wires with a rail with 3 coil packs mounted on it that bolts to the block and sits over the spark plug. As far as I know both were original and now had 134K on them and I was getting a miss on acceleration. Driving home from the shop it ran like a new Jeep!

Getting an older Jeep up to snuff is a project, but the reward is the way it handles.

Keep Warm and have a Merry Christmas.

Those are smaller than the original tires that came on the Jeep. Both my '91 and '93 YJs (Base trim level) came with 215/75R15 tires. I promptly went with 235/75R15 on both. The 205/75R15 is basically a 27" tire, and yes many trailers could use that size, but a true trailer tire would be an ST not a P (I don't think your tires are LT). Those tires don't show up on the Discount Tire website. I use it because it gives all the specs of a tire, not just the size, rev/mile and load. The original size of 215/75R15 General Grabbers are only $5 more per tire. But one advantage of Jeeps is that there are a lot of options and you can put on it what you want, regardless of what anyone else thinks or says.

205/75's.
Man it really shows you how badly they were determined to not have YJ's roll over like the stigma attached to CJ's.
Between those tiny tires and double track bars on leaf spring suspension sounds like a combination of acting out of fear and marketing people wanting to have a warm fuzzy blanket to throw over the public

I'd say that the lack of HP with the little 2.5 came into play. As weak as mine was I can't imagine what it would have been like with a larger tire size. Great when putting around or off road, but wouldn't hardly pull itself on the highway.

This is a very common issue with a very inexpensive fix.

If you are rubbing when turning, you can easily adjust your stops out further by adding locking washers as needed.

The bolt and nut are welded together at the factory but but the bolt has a lot of thread on it making it perfect to stack washers.

Turn the wheel all of the way to the passenger side then determine how many of your washers that you will need to stack on the driver's side to make contact with the stop before the tire makes contact.

Do the same thing for the other side.

Make sure both sides are tight and take it for a test drive and adjust as needed.

Both of my YJs ('91 and '93) were the base model but with the 4.0. At the time I also had an '89 XJ also with the 4.0 (the first year) that I bought in Toledo while there temporarily with my employer before volunteering transferring to S. Georgia to work on a special project. I love the 4.0 in the XJ and when I was buying the '91 I also test drove first one with the 2.5. I think the Wrangler S indicated the 2.5, buy the one with no descriptor (but called the Base) had the 4.0 and that was the difference. The 2.5 did not impress me so I bought the 4.0. I still have the window stickers in my files and both came with the 225s. The mistake I made with the '91 was not having the A/C added to it. In S. Georgia it can be brutal without A/C, even if it's a soft top. So it got traded in on the '93 with air and hardtop. It was a pretty flame red with a white top.
