Do you go with the 130/70HR-18 that fits a GL1800 Gold Wing, or what Metz front tire has the same rating as the 260/40VR-18 rear. Should you mix HR and VR rated tires on the same bike? I"m getting ready to get new tires as mine are severly cupped on the front on both sides, on the rear cupped or dished on the left side only. Its at the dealer now, see what they will do? tire pressure has been correct from day one Aug 16, my wife bought it for me, now I"m disappointed it needs tires. It doesn"t handle correctly , ridding two up, it"s terrible. Any ideas?
