i have a 1997 chevy 1500 extended cab 4x4. it has a 3 inch body lift but otherwise is stock. i had aluminum 16 inch rims on it with 31 inch maxxis mudders. my question is will i be able to fit 33's on it or will i run into rubbing issues when i turn, or even height issues? how is a 33 bigger than a 31 inch tire? can i just measure from my 31's and see if i have 2 inches around the tires and see if it would rub? any help with be great, thanks.

I have 285/75/R16 Maxxis Buckshot on a stock 1998 Z71. I think that's a 33" and that the 245/75 or 265/75 would be a 31" or 32"...not sure how they round off when measuring the tire diameter. Anyways, a 285/75/16 is fine on mine without any lift or anything. A lot of folks put that size on the stock rims on those trucks.

Here's a tire size calculator that will give you the tire diameters, etc. when you input the metric tire size (285/75/16 etc)
