i bought some 33x12.50x15 tires with the intentions of buying 10x15 rims, but i ran out of money. i have three sets of 8x15 rims too. everyone tells me that i need 10s, but my bro-in-law says that a forum for pittsburgh wheelers say that 8s are not only the way to go, but that they are less likely to break the bead. what do you guys think?
