I've found that I like the way the RT rides with tire pressures slightly higher than what Can Am recommends. I was keeping 20 in front, 30 in rear. But yesterday which was quite warm, near the end of a 3 hour ride, my TPMS app (FOBO2 Bike) warned me that the rear tire pressure was at 36, which I had previously set as the upper warning level. I was a bit surprised that riding raised the pressure that much, so today I let a bit of air out and lowered the pressures to 19 in front, 29 in rear. This all made me wonder what the upper limit for the stock tires would be.
