Ooooh. Lot’s of good info, here! I like the idea of smaller diam/aspect ratio (45) with wider (225) tire… if I can find it. I’d get the grip of the extra contact patch and in theory the loss in power and increased tire flex would be compensated for by the smaller aspect ratio. I’ll have to do a frresh search in this size. (Unfortunately, I don’t have tire rack wholesale access, so I couldn’t follow the provided links.)
