I decided to get sand tires (paddles) for my TRV 650 H1 but now I'm wondering if I got the right size. The OEM rear tires are 25x10-12 and the tires I got (based on the shop's recommendation) are 22x11-10R. It is considerably smaller than the OEM tire. Will I be ok or should I go with a bigger paddle tire? My destination is Glamis (Imperial Sand Dunes) in CA. Thanks.
