Tire question from a newbie Wrangler owner

I recently became the proud owner of my first Wrangler. The tires that were on it when I got it were some very trashed 33 12.50 15 mudders. The Jeep was almost scary to drive with them on it. So the first thing I did was replace them with some brand new Yokohama Geolander A/T-S tires of the same size. I wish I had taken some time to reasearch it more before I bought them because I'm not sure I like the look and have concerns about the size. It doesn't appear that the Jeep has been lifted, but I do still have 2"-3" of clearance to the fender so maybe it has. The body definately isn't raised and the suspension doesn't seem to be, but I don't completely know what I'm looking for. Anyway... The Jeep is a 4 cylinder with an automatic and I'm concerned about running it with these big tires. I'm worried it's going to trash the transmission. The previous owner said he already had to rebuild it about a year ago. Also, it has a pretty hard time of getting itself up and going. I would prefer a shorter "chunkier" look - nothing unusual, just a cool looking Wrangler setup. If I decide to go with a shorter tire setup what would you recommend? And, if I went to a 3" or so shorter tire, would I notice a difference in how it accelerates? I'm worried that I'm gonna burn crap up.

Thanks in advance for any suggestions! They're greatly appreciated. And... I guess one deciding factor as to whether or not I'm going to be buying more new tires is whether or not I'm able to sell the Qty-5 33's that I have now that only have about 400 miles on them...

I ran 32x12.5x15's on a TJ slow take off but ran fine. If you drive a lot of hills you may want to regear the rear. Tranny will be okay if you drive it like a Jeep not a race car. Wanna sell the old tires,lol. Let me know. I have a set of 31x10.5x15's right now they are AT's but might do a partial trade or buy your old out right,lol.

Jeepers are scavengers, it is part of the lifestyle,lol.

It's definitalely slow on take off. Seems to do a little better once you get going, but if there's a headwind at highway speeds... forget it!
I guess that's one of the things I'm trying to figure out; if I go to a 29" or 30" diameter tire will it take off and perform on the highway a little better?

The 5 tires I have now are brand new with only about 400 miles on them. Not sure what that makes them worth to someone but it's gonna hurt pretty bad if I buy another set of new ones and don't get some decent money outta the 33's.

I guess if the 33's aren't going to cause any problems, other than not giving me the exact look I want, maybe I should just suffer through them.
Dunno...

If you regear it you will have to do both the front and back. If you don't things will break when you put it in 4wd. The 4cylinder was never a speed demon on stock tires. It would definately help with a smaller diameter tire. There are only three real options to get your perfromance back to stock,
1. regear
2. smaller diameter tires (stock size for your rig)
3. engine swap

Here are a few pics. It's weird... they seem alot larger and more aggressive in real life. The pics actually don't look too bad

ahhh i see the problem now.. chrome bumper :P lol

Probably the cheapest and easiest is going to be dropping down to smaller tires..
Next depending on your mechanical experience, re-gearing will be a bit more expensive and yes, regear both axles..
Engine swap is the most involved and probably the most expensive in this case.

I hear ya on the chrome bumpers and nurf bar! That's how I bought it .

I've decided to start with smaller tires and see how things go from there. Droppin down about 3 inches in diameter. Hope it helps a little.

Now I'll hafta see if I can find someone that needs some like new 33s.

Better not drive over a curb or you'll be ripping your fender flares off.

Those tires are too big for a TJ on stock suspension. Sell them off (or trade them back to the store?) for some 30-31" tires on 15x7-8" rims and you'll be where you should be.

Thanks for the input! I have a set of 30s on the way. Gonna swap them out on Tuesday. Already talked to the tire guy but he can't take them back for me. Just gotta hope I can find someone lookin for 5 33x12.50 tires with only a few hundred miles on them.

You are in the situation as I am, you want a Jeep look which is mud tires but on the road they usually don't hold up. I typed wrong when I said regear rear I meant regear all. I just meant your rear gear is really not low enough for the tires. I am running 31's but my fifth is gone got it that way. I rarely run over 55 so to me I have very few problems, I do wish I could afford a regear and get to some 32's or 33's.

My cousin is getting a V-8 ready for his CJ so I am gonna go up in the motor area as for what I can get it from him for (Free) that is better to start with for me. I love family, free motor just help with the install of the 8.

Good luck hope you like the new tires, nice looking Jeep, though I am anti chrome.

Stranger....
I'd hate to regear due to the amount of work. Hopefully with these new tires things will be better and I won't have to think about it anymore. They're only gonna be a couple of inches in diameter larger than stock tires so I've got my fingers crossed.
The V8 would be SWEET!

KidRock....
I hear ya. But apparently, the guy before didn't grasp the concept . I have a number of things that I've gotta get done on it before I can start eliminating the chrome. Baby steps, right??...

You should be able to. Those tires hold up really well, handle snow very well, and are great on sand. If you were closer to Michigan you could likely sell them off to someone for their daily driver dune rig.

Smart move on the 30s. Your gearing will like it, and they'll do much better (being narrower) in the snow.
