If you had a slow leak at 60 then thats probably where your tire failure started.
I can't really tell exactly what killed your tire because it could be one of several things.
So heres just a few tips to keep your tires living longer.
Your tires are rated at 80psi max for average riding, anything past that risks tearing the nylon threading inside and the tire will develop lumps where torn or have a blowout.
(Running your tires at 75-80 psi will keep them alive longer)
Landing sloppy on your dirt scoot and hitting the side walls on hard objects can tear the nylon threading inside and cause damage or a blowout.
(Land straight, and don't hit the sidewalls of your tires on sloppy 180 bris etc)
Using tire slime only protects from thorns and small punctures, it is completely useless in park. (Use tire slime if you ride dirt)
So.. if you ride clean, use slime, and keep your pressure between 75-80psi your tires can last you.
Ive had a pair of these 80s last me 9 months before I decided to change them, and the 100s we are testing will more than likely eliminate how cautious you need to be with 80s.
Not saying that 100% of all our tires ever produced may be perfect, but this will dramatically improve their life.
