Bigger diameter tires usually worsen handling.

It won't be as squirrelly, because you're adding width, but overall your handling will suffer. You probably won't notice much to care.

Chris, just curious, how will it handle worse?

I have 30's and 32's... Going bigger will not only affect your handling but your gas mileage as well

With my 33 x 12 1/2's, it seems that cornering at faster speeds is more stable. It may be the weight of the bigger tires keeping the box from feeling so tippy, or the wider footprint.

But you also lose some turning radius going with wider tires.

Only if you add washers to the steering stop bolts will your turning radius be affected.

The steering will be a little stiffer. The ride will be a little bumpier. Your tires will grab more deformities in the roadway. Braking will be slightly more sluggish. It's the same reason luxury cars don't have wide, low profile tires, but sports cars do. You've got to make a few sacrifices in certain areas if you want some benefits in others.

Like I said, going from 30" to 32", you probably won't notice the difference that much to care, but you will notice some.

Depends on lift, gearing, and transmission, but 8" wheel on 4" backspacing will work.

can you get different width tires? or is it a standard size for my specs? (32's on 8")

sorry, im new!!

no. you can get different size in width, but the wider you go the more difference you will notice in all areas listed above.

Keeping width the same and diameter increasing will worsen (worsen?) handling, but I'm not sure I understand the logic of how even with wider tires, handling will decrease? Road race cars are all found with fat 10 - 12" low profile tires for handling, not little skinny things, so the connection between width and handling seems apparent.

But honestly, I think bottom line: don't road race your Jeep to where you need handling in corners. Right?

This is what I mean by "turning radius": With the skinnier tire, I am able to make a tighter u-turn. Whether this is because the wider tire makes it harder to crank the wheel over in the same amount of time, I'm not sure. But with the skinnier (stock) tires on, it is easier to steer in tight corners & u-turns. Also, the wider tire tracks differently than the stock, meaning, when I turn I get a chirp or squeal because not all of the width of the tire is following the track of the turn, like the stock tire size does. I don't know if these things make a difference in dirt or off-road applications, this is only what I've found happens on the street. I do not have washers added to steering stop bolts, my tires rub at full crank left turn.

I just put new tires on my TJ 2 weeks ago. I wanted a tire that was more agressive looking yet still road worthy. My stock tires were not badly worn, but my turning radius and road handling were attrocious. I went up one size so that I wouldn't have to add a lift kit. I couldn't believe the difference it made. It has great traction, great off road and street handling , it's 10 times smoother and the DW that 2 different dealerships couldn't resolve went away. So I think it all comes down to what tires you use

I just threw on 31's x 11.5's on 15x8 4"BS (back spacing) my TJ stock, for the past two years i had the stock p235's. It took a week or so to get use to them but they rock now! because of their width, the grab the hot top at high speeds if its uneven from high use. but anything lower than 60mph is fine. off road, the clearance helps and traction is 10Xbetter. no rubbing either.

typically a 31 inch tire measures 31x10.5x15 and 32's run 32x12.5x15. franchise shops like V.I.P, advance auto, etc. will tell you that you need wheels that are no less than 2" narrower than your width of tire... it's a lie, many guys and gals in here run 33's on 8" wheels.

how significantly will your gas mileage be affected with a pair of 33's? What if you get an A/T tire? Also, i heard somewhere that bigger tires end up wearing faster. Anyone know about this?

It is apparent. Road race cars are bumpy and a pain to drive.

A fatter tire will grab more road deformities. A fatter tire will grab for the grooves in the road. A lower profile tire has less room for deflection, so you will feel more bumps in the road. Why do you think they don't put 275/40 Z rated tires on a Cadillac? Z rated tires are a stiffer compound tire and don't roll as much as an H rated tire, but an H rated tire is a lot more comfortable to ride on.

Don't read too much into it, you'll just confuse yourself.

Track width doesn't change unless you change rims with a different backspacing. The track width is the center of the rim to the center of the rim (so center of tire to center of tire). Changing tire sizes will not change your turning radius. You might think it does, but it doesn't. The only way your turning radius will diminish is if you change your track width and you aren't able to clear your tires, and you have to compensate by reducing the steering input to keep the tires from rubbing.

When you are moving, your power steering is in full operation, so you can have pretty large tires and it wouldn't matter much. As long as you have the same track width and adequate clearance, you will still have the same turning radius.

I will say this, a locker up front will reduce your turning radius, but that is a different reason altogether.

If you have M/T tires like you said, will they perform well on a highway? I spend a lot of times at speeds around 70-80... how will they perform during these speeds do you know?

I have these in 31's, they are awesome. I everyday I am up to 75mph. I have 5k on mine so far, and love them. I am also on a lot of gravel roads just to get away. Its about 20 miles to work for me either way, gravel or highway.


i love these tires, they are WAY better than the BFG AT's i had on it when i bought it.

I drive on the highway every day on BFG KM2s. Before that I had Mickey Thompson MTZs. 50-60 miles round trip. Why should I stay away from MTs on the highway? If they were LTBs I could understand.

the only thing with mud tires and highway, make sure you rotate them regularly.
