I've had my BT45 on front of my trike now for about 9,000 miles. After coming home this week from Colorado I noticed cupping is getting bad. I've mostly run 40psi in it with it occasionally getting to 37-38 before checking. Still has lot of tread but made a slow speed turn during trip and noticed a wobble. I'm guessing this is due to tire cupping? Only does this occasionally. Going down road it's smooth
