tire size with stock springs

I've never been a fan of lifts and oversize tires. When I bought my '95 YJ it already had a 2.5 inch lift with 31s. The kid I bought it from said he'd just had the lift installed. I can believe that because the TrailMaster Suspension paper tags are still visible on the springs.

I'm exploring some options. I'm looking at returning to stock springs and shocks, but I'm not opposed to running a slightly taller tire to help get through the snow.

I'm not a mud fan, but a skinny tall tire had always helped with getting me into work after a 10 to 12 inch snowfall. I owned a '92 Geo Tracker in past years, always had great luck with a slightly taller more aggressive tread tire.

My question....if you have a stock height jeep how tall a tire can you run without interference? Or are you pretty much limited to the stock size?

I had 30" mud terrains on stock suspension when I first got mine. The knobbys may have rubbed a little at full turn but can't recall? I remember it not being much of an issue. I think that would be your max if you want taller with stock.

Ran 31x10.50 for 10 years beating around the farm..they rubbed the fender flares occasionally on flex and they would rub a little a full turn but it's not so bad you can't drive it..worth it in my opinion

I too ran 31x10.50 when I first got mine on stock suspension. It rubbed the fender flares pretty bad, but I didn't get any rub when turning. I now have the same tires with like 1.5-2" of lift. If you are going to get stock height springs check out General Spring out of Kansas. That's where I got mine from and they're very nice.

I was going to say 31s as well. That seems to be the general consensus. I ran 30s on my sagging stock springs. With my 2.5" lift, I can run 33s comfortably. I am not a big fan of stuffing the maximum tire size underneath a vehicle. I like sitting a little above the tires to get some suspension articulation, my friends stuff tires bigger than what they should, and they cannot go over obstacles without worrying about rubbing.

My suggestion would be to keep those 31s. Those have a great balance of street manners and mild trail performance. I'd also keep the lift. Your Jeep has a nice stance. Chances are, there could be some BS like a body lift or shackle lift that isn't needed in your circumstance. Throw on stock length shackles, and use stock body bushings. Check for patches on the lift kit, such as a transfer case drop. If you have no driveline vibes with no TC drop or SYE, you're good to go.

Thanks for all the replies folks. General consensus seems to be 31s or smaller. I'm still mulling this over, but if I do go back to stock I'll definitely go with a smaller diameter tire.

I don't know if the shackles are stock length or not. It doesn't have a body lift, but there is spacers between the skid plate and frame that lowers the plate maybe 1 1/2 inches.

I guess if I use stock springs, I'll have to get some stock length shocks too.

Thanks again.

That's a transfer case drop. Stresses motor and transmission mounts. You may not even need it. Post pictures of your spring shackles and we can tell you if they're stock or not.

Here's a pic of the shackles. The bolts measure 4" center to center.

Thanks for all the info folks! I'm glad they're stock, that's one less thing to deal with if I go back to a stock suspension.

Thanks again.

Glad I am not the only one going back to stock height.

When I talked to the guys in the shop at a dealer about doing it they looked at me like I was insane.

I just told them that for all my years in the US military, all I ever drove was stock height Jeeps and had no problem getting around in all kinds of weather!!!

Yeah I want some 35" Dick Cepek Extreme Terrain on SOA plus 2.5"... But I hate those count shackulas, I have bent them up badly because they drag on every ledge I want to climb, bye bye approach angle.

For a Jeep that sees joy trails and streets, stock height or a modest lift is plenty.
