33" tire fitment

Have a 2004 Columbia which has the 15x7 aluminum wheels. I'm going to put a budget boost on it and am interested in getting a 33x12.5x15 inch tire. My question is this ... will that size tire on that rim make the tire stick out further than the factory fender flares? Thanks in advance.

What width are the stock tires? If they're 9.5, they will stick out about 1-2" more (if my math is correct). Also, do your research, 33" tires on a 2" BB might not work out too well, you may want/need to look into a 1" body lift as well. I'm no expert on the setup, but a quick search on this forum will lead you in the right direction.

Also depends on the whether or not you are running stock or aftermarket wheels, and the backspacing on the wheels you are running. Also depends on your flares. If your Columbia Edition has the Sahara/Rubi width flares (4.5"), it gives you an extra inch.

Here's my old 33x12.5x15 tires on a 15x8 aftermarket wheel with 3.75 backspacing with standard TJ flares (3.5").

12.5" tires on a 7" wide rim is pushing it. You would be better off with 8" wide wheels for that size tire.

Thanks for the replies guys. The stock wheels are 15x7 and are painted graphite gray as part of the columbia edition as are the fender flares so that's why I don't want to change either. The fender flares are not the larger size like the Rubicon. I am not married to 33x12.5x15, I see some tires available in a 32x11.5x15. Right now I have 225/75/15. I'll have to measure how much room I have with them. I just hate the look where the tires stick out further than the fender flares.

There are a few tire manufactures that sell a 33x10.5x15 tire. BFG KM2 mud tires and their all terrain tires come in that size.

That may keep you withing your flares with the stock wheels and still be able to run 33's.

The OP could also look into 11.5" tires or the metric equivalent (although I don't think they make those in a 15" rim).

I too would suggest the 10.5" wide 33"s if you are dead set on running those rims.

Also be sure to add bumpstops. You will likely need to add a 1"-1.25" BL or trim your flares up about 1" to avoid rubbing offroad.

2 Inches will work just fine. I drove around for a month with just a 2 inch spacer in the front and 33X12.5

Even the 10.5 width extends a little further than the factory flares on my '98. I don't know if your model has wider flares, but if you want the tires to be completely flush you might have to stay with the 225 which is 9.5 inches.

What wheels are you running with those tires? Aftermarket wheels will push them out past the flares. The stock wheels he is running may just work.

Good point...the wheels were already on there when I bought it - the center cap says "PCW" so they're presumably not stock.

Thanks, you guys are great! I was just worried that 33x10.5 would be too skinny but they look good on Ed's.
