33x12.50 or 33x10.50?

I am getting ready to purchase new tires and I am having a hard time deciding between the two sizes. I am also getting new wheels, 15x8's. Right now I am running 33x12.50 on 15x10 wheels. I like the look, but I am ready for something new. Any advise and/or pics would be greatly appreciated.

I'm not a big fan of 33x1050's

I think the tire looks too narrow for how tall the tire is...just my personal opinion though!

I agree but you do get better mpg's with 10.5s. And theyre impossible to find almost. Id go with 12.5s cause they look great.

15x8 rims are popular

I tried to order 15x8, but the salesman at tirerack.com said I needed 15x10, so that's what I ordered.

The salesman was wrong....

15x8's are perfect for Wranglers with a 12.5" tire. You can air down more offroad without worrying so much about loosing a bead. A 10" wheel will work, but you can't air down as low, and they are heavier for DD, thus further reducing mpgs.

I have 15x10 wheels with 33x12.5 with no issues at all. We have ran a 10" wheel for years on several TJs with no problems. Just make sure to get correct offsets. You may also need to get wider fender flares.

I just bought a 2010 Jeep Wrangler Unlimited Sahara - what do you guys think about putting 33" x 12.50 tires on 20" rims? I would like to put 35's on but I think I would have to lift it and I don't want to do this while it is still under warranty. Can I fit 35's on at the stock height or do I need to do a 4" lift?

I had the wider fender flares already by I took them off because I went with tube fenders.

So can you run 15x8 rims with 33's with stock YJ suspension? Will they rub springs on hard turns? Do you have to get offset rims to do it with stock suspension?

33's will be in your fenders on a stock yj.

Wouldn't there be a difference btwn what kind of conditions you wheel in as far as the 12.5's and 10.5's. I was thinking of 33/10.5's later when I need new ones. More so b/c I can hold onto my stock canyons which I actually like.... I guess the 12.5's would work better in sandy conditions and the 10.5's would work better in mud or am I off track????

You are on the right track. The 10.50's will dig down deeper and grab. The wider tire will sit more on top. I have 12.50's now and I like the stance. I am just going with a slimmer wheel.

YJ Offset

I have a 1995 Yj with a 4in suspension lift and a 2in body lift. I am getting ready to order wheels and tires and have a couple questions. Will 35/12.5's clear ok or should I go with 33's? Also what offset and backspacing would I need to get them to clear while still being reliable on the bearings. I know this is probably asked a lot but I don't want to go the wrong route and get in a trouble.

I have 33" x 10.50r15's BFG KM1 M/T and I really like the way they look on my Jeep. I also have a total of 5" worth of lift, if I go any higher, THEN I would get wider tires.

On my tj I had 10.5 swampers and they cut through mud like butter. I went to a 12.5 and loved the stance and look a lot more. They were seamless and did great in the mud as well but were so much better in sand and snow. I had a 4" lift and they were 33's. No rubbing at all.
Now I have a yj. Not sure what I am doing yet. Oh yeah and I had 15x8 steel wheels. Worked great

Question for you guys.. Just bought a 97 wrangler sport 4.0 auto.. I want to do the 33x12.5x15 on it and a lift. Now my question is do I have to do anything with the driveshaft angle or something? Things I hear but don't get the getails. Any help would greatly be appreciated

Depends on how much you are lifting? Body or suspension?

Similar but different

So, reading this thread has helped me some as well, but I do have another question . . . I need new tires badly. I have 2001 TJ with no lift. The current tires are 32x11.5x15. Haven't had any trouble with rubbing at all. I will most likely replace with the same, but I need to buy an extra wheel for the spare (the current spare is a stock tire). What I hear you guys saying is that I could by a 15 x 10 or a 15 x 8.5 wheel. Is that correct?
Thanks!

If you are going with the same size tire you have now I would go with a 15x8 wheel. I currently run 33x12.5's on a 15x8 rim.
