  1. Your site offers a wealth of information on vehicles of all kinds. Great site!

    This post is straight and to the point. I like that. Especially since I am completely unfamiliar with the topic. I didn’t have to wade through an ocean of information to find how to measure rims.

    Is the post aimed at people wanting new rims? Or is it also useful somehow when choosing tires? I’m assuming rims since I could just look at my tires to get info for tire replacement.

    The diagrams are perfect. The only measurement that didn’t have a diagram was “backspacing”, and if you could provide readers with one it would be perfect, in my opinion. I cannot visualize what you are describing otherwise! Just don’t know enough about rims.

    Good luck with your site! I think it’s going to do great.
