I have stock 16"x7" rims and i was wondering if i can fit 33"x10.5" tires on them?? sorry, i realy dont know! I dont have money for new rims and since i recently just addes spacers and aals, my tires look tiny!! But will i be able to fit 33's with only 2" lift by the spacers and aals? If not then i will get a BL. how many IN. will i need to fit them? THANKS

 

I can't recall seeing a 33x10.50 in a 16" tire, but you can get a set of 255/85/16's. They are roughly the same measurements, maybe a hair taller, and it's recommended for a 7" rim. With your spacers and aal, they should be a great fit. If you needed a BL, you would only need 1 inch.

Tires that measure 255/85 are also much cheaper than similar size tires. I'll be getting some for my next set to run on my 7" rims -

 

285s are 33x10.5 and 305s are 33x12.5 You can fit a 12.5 on a 7 but there would be more contact area. Alot of guys are rolling 33x10.5 on factory 7" wide wheels. Most people recommend a 4" discrepency in tire/rim width.

 

Tarheel - check your measurements again here - Metric Tire Conversion

You'll find the 255/85/16 is closer to a 33x10.50, while the 285/75/16 comes in around a 32x11.50 and the 305/75 is a 34" tire. Additionally, there would not be more contact area with a 12.5 over a 10.5 on a 7" rim, there would be less contact. The narrower rim will pull the sides in more, creating a crowning affect down the middle of the tread. You can run a 12.5 on a 7" rim, but you should rotate them more often to prevent bad wear from crowning.

I've had a set of 285/75 BFG AT's on a previous truck and they measured 32.5" inches tall. Put a 255/85 next to a 285/75 and you'll see the 255 is a little taller and a little narrower than the 285 -

 

I have BFG MT/KM and their sizes are as follows....
305/70R16= 12.2" on 9" wide rim and 33.1" tall
285/75R16= 11.3" on 8" wide rim and 33.1" tall
265/75R16= 10.5" on 7.5" wide rim and 31.9" tall
255/85R16= 10" on a 7" wide rim and 33.3" tall
