Upgrading Tire size !!
 
Hi, I got my 1999 SE jeep about 5 months ago and I think it's time for me to get new tires. I currently have 215/70/R15 I think, (not 100% on the aspect ratio), but the tire is around 28" non the less. I'm was wondering if I would be able to use 265/75/R16's (31.6") or will I be limited at 265/75/R15's (30.6")? Also I will also need to buy new wheels if I am able to get the R16's so I was wondering how would I go about finding the correct wheel size width for the new tire?

P.S What's a good price for a set of 4?

My first question would be, Why 16" rims? I've been around wheelin a long time, and made a mistake about 6 years ago. I kept the stock 16" Moab rims.. as a result I'm paying nearly 200 more for a set of tires, and I have way less selection of tire sizes.. Rim width to tire size? There is all kinds of info all over the web, but I think the rule of thumb is for the tire to be no more than 3" wider than the rim... I may be corrected on that by some one that knows for sure.. 31s will squeeze in under a stock suspension. ;)

15x8" wheels with 3.75" backspacing.

31/10.5/15" tires

1.25" body lift. 1" motor mount lift

Novak shift cable

Very good basic setup

I've been looking for 265/75/R15's now on behalf of your advice, do you have any recommendation on where to look for a good buy?

Be careful with the 265/75r15 tires. Often times even though they are the same brand and type of tire as the 31/10.5/15 they are not load rated for trucks and are intended to be used on "light suv's" like Honda crv an Toyota Rav4. That's why they are usually cheaper.

All 31/10.5/15 all terrain tires are truck rated.

X2^ if you are going to go with a 15" rim, get out of the metric business. as far as good deals? Many big box web sights offer great deals, but I have found by the time you have the tires shipped, mounted and balanced, you haven't really saved very much money, and you have pissed off your local shop because you used them to mount and balance, but not to purchase the tires. I use a very small mom and pop shop, it is a two man operation with low overhead and very good prices. I did make a mistake three years ago and got my last and only set of tires on line. When all was said and done, I saved about 50 bucks. And I am having a very difficult time trying to prove that the tires are seconds. These BFG KM2s will be lucky to see 25,000 miles.

when i was checking on tire prices..the 35s were 40$ cheaper than 33s at that time. however you have to take into consideration if your driveline can handle 35s.. which may cost more than what you may save on the tires. with that said i ran 35s on my stock d30 or d35 for about a year before my spider gears got chewed up.

New Tires !!!!
 
I just replaced my wheels and tires on my 2013 JKU. I got rid of the 18" 7 spoke wheels an tires and went with a set of Black Rock Vipers (Black) 17 x 8 with a set of Duratracs 285/70/R17.....OMG what a difference !!!!
