Is anybody using the M/T sportsman "i" tire's. I'm intrested cuz they have 12/32" of tread vs 8/32" on the sportsman pro vs 5.5/32" on drag radials.

they look like they grip well!!

 

I haven't run on the "I" series but I can vouch for the Sportsman Pro's. They have drag racing compound and a 2 ply wrinkle wall sidewall like a slick. I've been able to cut as low as a 1.585 60 ft. so far with them. I heat them up and they hook. It depends what you want out of the tire. I like the Pro's because I'm still driving on the street occasionally, if it was a trailer queen I'd run a slick.
