Re: Replacement tires on stock wheels

If you are going the mid drop then go with the 305/35/22. Heaps have done it on here with no issues. Of course you will need 22" wheels though not the 20's.

Re: Replacement tires on stock wheels

New jeep summit coming in with stock 20" tires. I have heard that they are not good for snow!!!! sheesh(is that possible?)......Is there an allterrain tire replacement for 20" stock tires(size????)that would be as quit on the open road an good in snow????..........I might be able to trade brand new tires in for replacement at a tire center, if I knew which one's to get......sonny

This post makes no sense and the poster has trouble understanding comparisons. HTF would one attempt to imitate a Vette or Mustang in a Jeep anyway? *mindisblown*

Your performance isn't going to change either way IMO. Strictly looks. You can't do 305/45/20, your wheels and tires will be too big, look even more bloated than they already are and will almost definitely rub when you drop it. If you find one of the very very few 305/45/20 tires out there to put on, you'll get a little more width, but the tire profile is going to be bigger too. wheel and tire setup is going to look like a Ram Truck wheel and tire. Your tires sidewall is going to be almost 5.5". For a comparison, the sidewall you see on guys running FR22's and 285/35/22 is 3.93". If you try and put on the 305/40/20 (good luck finding many once again) then you'll look like those people who try to make their stock wheels look bigger by putting a smaller sidewall tire on it. It looks odd and like the wheels and tires aren't big enough for the vehicle. Your only way to do this right, and look good, is to buy 22" wheels and go with a 305/35/22 tire.

What does this have to do with this thread.....or vehicle section????

Except that this would require a 22" wheel and it will absolutely affect his performance more than just getting a wider tire.

The guy said that he thought the 45 meant the height of the sidewall, now you're getting into reading comprehension issues or just rubbing it in after he pointed out his mistake himself. Let it go.

Go with the 305/40/20 for looks and better performance. Be weary of the speedometer differences, here's a direct link to the pertinent information:

295/45-R20 vs 305/40-R20 Tire Comparison - Tire Size Calculator

You'll have more tracktion with the wider tire, it will look better. Your sidewall will actually decrease significantly on the 20" wheel with a 305/40/20 tire.

Going up to 315 it gets dicey, the problem there is that not all 315s will fit properly from what I understand. It's not an issue of actually fitting or rubbing, but the tire will get squished and cause warping and uneven wear. I know of folks running Nittos on stock rims but I'm not convinced. According to the calculator the 315/40/20 is workable and again results in smaller radius than stock wheel/tire.

I've got about 10k miles on my original tires now and I'm starting to look into this. I'm really curious if the speed differences can be "tuned" out somehow on our jeeps either at the electronics readouts or by adjusting gear ratios.

As far as the 22"s go if you can afford them and like the looks go for it. I've been trying to educate folks that even if you get a good 22" wheel that's lighter than the stock wheel things will be different and not necessarily for the good. Wider tire means more mass distributed farther away from axis of rotation, meaning greater moments of inertia for the wheel and ultimately more angular momentum for equivalent rotation rates. While I think in general these differences are in the was for guys that like to go 0-60, for those of us who care about actual road track performance this matters more. And by "good" 22" wheels I mean really expensive ones, cheap and lightweight replicas are something I'd never subject myself to. I just don't trust them at all. For pure performance staying with 20" is most likely the best, maybe getting a wider high quality wheel at 20" is the better option. Anything smaller and I'm not even sure what will fit over the front breaks on our jeeps, but you can see the Z28 camaros went with 19"s and all around 305s for performance, and it works very well.

Re: Replacement tires on stock wheels

Do whatever the hell you guys want with tires.

As for the the benchtop physicist Nivas. In theory, his info is correct, in reality, it's bullshit for us. We aren't racing NASCAR, F1, or even dirt track here. 99.999999% of driving is on public roads. Teh key is your overall diameter is as close to stock as possible, and your overall width does not cause rubbing / turning radius issues.

Re: Replacement tires on stock wheels

In theory and in the real world is the same chit. Physics is the law. Lots of people try to squeeze more performance out of these jeeps, sticking 22" wheels on them is not one of the ways. If you like the look, by all means. That's all it is, for looks. Carry on now.
