That's a good point. I completely forgot about those. I never calculated the weight of a 15" wheel and tire combination. I was looking at RPF1's and they don't come in a 15" wheel with our 5x114.3 bolt pattern. Depending on the wheel and tire widths and tire sidewall I'm sure it could be even lighter than the 16" combination but at some point you're trading weight for contact area and sidewall flex.

Speaking of RPF1s.... They are pretty well known for being a great light weight option right? I've noticed manufactures aren't providing wheel weights on their spec sheets (that I've seen). I like the RPF1 but I'd prefer a different wheel just for the sake of having something a little different but I dont want 100lb wheels lol.
