    33\" tires on factory wheels

    I have 31.10/50's on my factory wheels right now and was wondering if I have to buy new wheels to fit 33's. After new paint, lugnuts and caps, I think these will look OK, and I really want to save the 600.00. is there a particular width tire I need to consider? I'm not positive, but I think these are 15x8 wheels. thanks for any follow-up posts!

    I just sold a set of 33's on stock wheels and they did look good. They were 33-12.5's they "pooched" out from the rims a littl, But I dont mind that look. I think you cant go wrong with saving some cash. You can always buy different set of rims later. Just my $.02

    If the rims are 15 X 8 you can run 33 x 12.5 x 15 just fine. If you don't have a lift I probably wouldn't do that though. Upon full compresion you are likely to have a tire rub and possibly cut the tread. I know I did it. Each vehicle is different though.

    If you are not going to lift it and just want bigger tires, go to 32 X 11.5 X 15. They should fit without rubbing and are close enough that the power loss will be minimal and the speedometer won't be too far off.

    I'm planning on lifting it 4". I think I'm going to go with a Rough Country system (springs all around, shocks, steering arm etc...) I'm just going to do it all at once. I have whimpy little 3.08 gears and a 305, I'm already looking at new tires (these new Generals are NICE by the way) and new gears to replace these and I don't want to add 800.00 to the mix for new wheels. I don't care if they puff out on the sides a little, so long as they don't pop off at 60mph. I mean, the grand total is already over 1,500.00 without wheels. That's alot of bones.

    I am running 33 x 12.5's on my stock 15x8 Ralley Wheels right now and I haven't had any problems at all.

    I had 33x12.5 on my stock blazer before I lifted it. If I hit a bump just right or too fast, it tore up my body. There are still marks where it rubbed and tore metal and stuff. I wouldn't do it.

    Keep the shiny side up, and the greasy side down.

    I have BFG 35x12.50-15 M/Ts on my stock rims. I wouldn't go any wider. The narrow rim helps keep the bead seated when aired down. I also like the steel rims ability to take a beating.
