I have 15 avid1 rims on a 91 Honda. How do I found out my bolt pattern to order newer and better bolts for my rims? 205/50r (tire size)?

I shop at Amazon.com. I registered my van there. Through my account, I go to a page to shop only for parts that fit my van. When I shopped for rims, it would say, "This part fits your van." It also listed the bolt pattern of the rim.

This is assuming that your car's lugnuts are original.
