wheel spec

looking to get some pro comp wheels but I don't know where to find the diameter anyone have that info?

 

Send a link to the wheels you are looking at and I can tell you the diameter of them. If you're asking what size you can run Tires/Wheels see the link below in my Signature about Tire Sizes for these trucks.

If you plan to run larger than 265/70/17 or 265/75/16 or 265/65/18 you'll have to trim some plastic and possibly some grinding or cutting to keep them from rubbing. Also try the search function as this is a very frequently discussed topic.
