Tires/new rims


I just ordered a 3in. Lift kit and wheel spacers...I plan on getting 31/10.5/15 tires. I want to get new rims. I need to know the dimentions of 15in rim that will work with the tires as it will be an aftermarket rim. Like 15 by 8 or 15 by 10.  Also lug nut specs .


The manufacturers of tires publish dimensions AND the allowable rim widths.  For a 31X10.50R15LT, the allowable rim width is 7" to 9".

Lug Nuts?  Those are tied to the studs - which vary.  Here's a guide published by a specific manufacturer of lug nuts and related parts:

I have over 30 years experience in the design, manufacturing, and testing of tires. I have served as the technical advisor to the "800" number. I have authored or co-authored many publications - usually without credit. I can answer almost any technical question, but please don`t ask me to compare brands. I probably have prejudices because of my work experience.
