:-staun Okay I am thinking about putting a 2 inch leaf spring lift in my f150 how big of tires can I get on there right now i have 235x 10.5x 15 what do you think

 

235x 10.5x 15 is NOT a valid tire size!

With a 2 inch lift, you should typically fit 33's. There may be rubbing depending on your rim width.

 

I know that my tire size was wrong but i couldnt remember how wide my tires where so i just put how wide they were in inches i am sorry if it offended you

I think you might be pushing it to get 33's with only a 2 inch lift. I am not saying they won't fit but i would think they would be pretty tight. I would go with a 4 or 6 inch if I was doing it.

Haha, no I'm ok. I just think the metric tire measuring system is ridiculous. Actually, 235 is the width... in millimeters!

Take this tire for example: 235/75 15 The first number 235 is the width in millimeters. Next 75 is the PERCENTAGE of the width for sidewall height. Lastly, 15 is the rim size in inches. Here is how to figure out how high and wide the tire really is:

1) Divide the width by 25.4 to get inches: 235 / 25.4 = 9.25 This is the width in INCHES.

2) Now, multiply by .75 (75 percent) to get sidewall height: 9.25 * .75 = 6.94 This is the sidewall height from rim edge to outer tire edge.

3) Finally, take 2 times the sidewall height and add it to the rim size to get the total tire height: ( 2 * 6.94 ) + 15 = 28.88

So now you know a 235/75 15 tire is 28.88 inches high and 9.25 inches wide!!! Whew... what a drag. There are online tire calculators to figure this out for you if you forget the math.

 

ok here we go..... with 2 inches in the rear on my 93 i could fit 33 easy would look better if i had them to tell the truth.. thanks for the tire calc. that is cool. why cant they just do that instead of all the confusing crap ohhh well hehe. ummm back to issue of the 33's they wont fit on the front with out some work. dont know what your plans are for sure but that is my 2 cents and nothing more.......

 

 

dude, listen to riffraff- i've got 32 x 11.50 r15 on 15 x 7 rims on a stock suspension 95 4x4 f150. no rub - unless you slam into a huge rock. 3 inch body and new coil spring up front(add 2 inch) you can fit 35 x 12.50 r15 . good luck -have fun.

 

I ran 12.50.33s on my sock front end. But I rubbed on the inside when I turned sharp. And I had the heavy 88 F-150 with the dual shocks on each side. The rear of the truck could probably take 35s if called for.
