I'm planning on running 15" next year, but for the finish of this yr
I've run out of tires (13") at least for the moment... I crew for a SRF and he has many cast off tires with some life left in them.... the SRF weighs ~ 1350# my CRX weighs ~ 2050# .... the question is would those tires be safe on the CRX considering the additional 700#
