My question was never are they SAFE i'm NOT worried about this, my question from the start was will they LET me in for track day with them? I don't have much time before track day, i have never changed a tire (on a bike) and they still have lots of life in them. I don't want to THINK about crashing as i hope i don't go down, I am just trying to know if i have to PAY someone (stealership) to change my tire, or do i need to learn REALLY fast how to change tires. I'm sure i wouldn't have any problems popping into Alberta Cycle and grabbing a new set of tires. TBH if i was worried about it causing my tire to blow or deflate i wouldn't have asked and would have just got new tires. I do thank everyone for everything they have said as I AM NEW to bikes/ track and I will be the first to admit it, so I'm sorry if i ever come off as a (insert abuse hear XD)
