I ride at 9 lbs. front and about 10 lbs. rear on kenda heavy duty tubes and 6 ply tire kendas also no rim locks!

 

Moose has heavy duty tubes and they retail at $20. from parts unlimited

 

I only ride in sand and mud now...no more street riding. The Kendas with the 11000 miles--was that street and trail mostly? I would guess it was since I only have 11 HUNDRED miles on mine and I am still using the stock Dunlaps for another day until my other Starcross gets here.

Anyone know the science behind what spins the front tire and pulls the valve out since I raced an hour and a half with no problem in the tight stuff with no whoops and then within 1/2 hour in the sand whoops, the front valve was completely missing. ( I was hitting it pretty hard since I drilled out the exhaust and opened up te snorkle.)
