I am ordering a set for a friend for a gift. What is the stock sizes , and what are you sand dune guys running?

 

stock 16/40
I run 14/40 in sand with 22x11x10 9 paddle extreme haulers
Alot of folks run 15/41,42,43 depending on tire selection and power of the machines and whether or not they are duning or drag racing or hill shooting.

 

16 front/ 40 rear





bigger

 

thanks a million...
His ride has a stock pipe that we hogged out, a k&n, rejetted, no lid , and runs a 8 paddle tire. I don't know the name , but they have short angled blades. He weighs 240. What do you suggest? I should have asked the first time......thanks in advance
