Top questions: 

How can I tell what size of tire I need?
It is best to use the same size tire that came stock on your vehicle. If you decide to change the tire size to an alternate we cannot guarantee fitment. You must use the same size bead (ie. 15" or 16") as your rim size.

Can I get matching casings (sidewalls)?

Yes. We always strive to send out matching brand casings. Occasionally the model within the brand may be different. For example, all four tires are Bridgestone but two may be Duravis and two Duelers, all four with the same tread design and load rating. If we cannot send matching brand casings we will call you to tell you what we do have available and see if that will work for you.
