I think Im done trying to rotate in the spare. I always buy 5 new tires and every time with these big tires it seems like one tire just wears bad and can’t be balanced correctly . It starts causing a vibration and I finally give up and throw it on the back as the spare. Or one tire gets a huge chunk from wheeling and earns spare duty. Or one drives over a 6” lag bolt, or, or, or…
They just never last equally so the 5 rotation lasts about 10k miles at most.
So, I knew about pizza cutters and love them but what is the 16” pizza cutter version of a 35” tire?
Also, carcass design is so important for getting sidewall flex. I bet a thin sidewall has great contact and flex. But do you really want that on the trail with all the sharp CO rocks? (Think GY DuraTrak or whatever that super popular thin walled tire is?)
