Will 30x9.50x15 tires fit my 92 xj without issues or modifications?
Thanks

On stock rims or equivalent of? If so and your suspension isn't sagging very much they should be fine. There is a chance you may hit the lower control arms a bit when making TIGHT turns. You can adjust the stops to fix that though. 235's would be no problem at all.

Without the equivalent of an "up-country" package (basically 1" lift from factory) 30x9.5/r15 tires will be right at the limit of what you can fit. I don't think you will rub the control arms when turning, but if your suspension is not fresh you may get some rubbing on the flares when in off-road conditions. Hard to predict from here if that will be an issue for you. A picture of the vehicle might help.


I lifted mine 1" (basically a clone of the up-country package) and the 30x9.5/r15 fit with room to spare.


Most folks in your position would go with 235/75/r15 tires. But chances are, if you can fit 235/75s, you can probably fit 30/9.5s. They are pretty darn close in their dimensions.

For price and selection, 235's are a much better choice. I had 30.5's on my TJ and I have 235's on my XJ and you're really not gaining a noticeable increase with the 30.5's.

30x9.50 will probably be a 6 ply and most 235s are 4 ply and not as strong.

not really. Most of the popukar choices in 235s come in LT 6 ply versions

Ultimately it's a personal decision - 235's work perfectly and look good. 30.5's are slightly bigger, and hence you can get rub on a stock suspension.

My experience with 30.5's (4-6 years ago) was that 30.5's were expensive and hard to find. My XJ came with very new 235's, but window shopping gave me the impression 235's were much easier to find and less expensive. Considering how close they are side-by-side (which I did - I pulled the best tire off my TJ for a spare), I'd vote for the 235's, but that's just my opinion.

It is good info re: 4 vs 6 ply - I'll keep that in mind if/when I replace my current tires. I will say, I put 300k over 3 sets of 30.5's (mostly on-road, but I did do some wheeling) and never once had a puncture. I hope and expect the 235's will be the same, but I've only had them for a few months and haven't "tested" them yet.

So....we are talking a width of 75?
Also...words on BF All Terrian TA vs Pirelli Scorpion plus vs Goodyear Wrangler vs BF Advantage?
Considering cost, I am leaning toward the Pirelli Scorpion (current $80 rebate from Sam's)
ON a 92 XJ, no lift.

I had Goodyear Wranglers as the OEM on my TJ and they were decent tires. I liked the BF All Terrain a bit better for the drive, less so for the wear. The best set I had was Michelin - I got 120k out of those tires and they were great in all weather, dirt/mud, etc. I've never tried the Pirelli.

Yes 235x75xR15.

235 is the width @ 9.25".
75 is the aspect ratio(75% of the width)@6.9" from the edge of the rim to the top of the tread.

How will you be using this XJ? Also maybe some pics will help. Here is a stock XJ with 235/75-15's.

Looks great....Which Michelin did you use?
Not sure exactly how I will use the vehicle, just want to be able to do some off-road but only for exploring purposes

I can't recall the specific model. It was the 2nd set of tires on my 00 TJ - I got them as an X-mas gift from my parents, but I know they were expensive. Michelin ended up discontinuing it (they didn't even make a 30.5x9.5xR15 as of 6-8 years ago). I had 90k on the Jeep when I got them and 210k on it when the tires finally wore out.
I actually have a pair of them on the TJ that I got used when the TJ was close to the end of it's life as a DD, so I'll take a look at them when I get home from work and let you know.

Someone mentioned that depending on where you live is a factor in how good the Michelins are - since I live in the Northeast and it's cold, snowy and wet, the tires were awesome. Folks that live in the Southwest where it's hot, sunny and dry have problems with the Michelin's drying out.

I'm not an expert or anything - I can only report on my personal experience, but if my XJ lasts long enough to need a new set of tires I will definitely look to get a set of Michelin 235's on it.

i am not a fan of any of the tires in your bunch haha...i work and deal with tires all day as part of my job and i'm noticing you just want something cheap....avoid the wranglers at all costs. Worst all terrain on the market imo. Those bfgs in tour list are, ok. The pirelli is a decent tire but theres better in that price range.....lookn into the ironman all terrain. I sell the crap out of those and for how cheap they are, they getvrave reviews from my customers and i tries them out as well. Good tire far exceeding their price.

I have pathfinder sport s/at's 235/75/15 and I really like them. They seem to have good traction offroad and they were cheap.
