I was wondering if anyone has tried this, to swap out the OEM tires before they accept delivery. We are expecting our delivery RP-EX-RES in April and given what I have read, the tires that come w/ the new vehicle is not all that great. Instead of waiting 20K miles or spending an additional $600 or so on better tires, has anyone tried to upgrade them before they take delivery? Or has anyone been able to trade them for a better set of tires afterwards? Thanks in advance.
