hi
has anyone tried this size? do i need to do any clutch modification for it?
my OEM tires are dead and need new one...
i have here in option the following brands:
CST STAG
SUNF
DURO
GBC
do you have any recommendation?
thx

From reading what others have said, you should go to the B2 or C1 clutch setting.
I'm sure NMKawierider , or one of the guys that upped their tire size can answer that a lot better.

Yeah you will need to clock the secondary to B2 for sure. And I like GBC tires. The Dirt Commanders are a great choice for most anything.

I second the GBC recommendation. Most, if not all, of their product line is an 8 ply rated tire.
