Most of us are running Hoosier or Burris tires on our Super Mods. I don't know what the speed rating is on them, but we have never had any tire issues. We ran at Selinsgrove, PA a couple of times, last year. It's 1/5 mile. That's where the guy with the radar gun said he clocked Joel at (I believe he said) 76 mph.
We ran at Shippensburg, PA twice so far this year. It's 1/5 mile. Then we ran at the Stonybrook track in Stoystown, PA a couple of weeks ago. It's a tri-oval and the track owner told me it was 1/4 mile. AND, I lifted and even used a little brake going into most of the turns at all three of the tracks.
I haven't seen any of us have any motor problems on the big tracks, as long as you get your gearing right. I think I've been somewhere around 3.5 to 1, from the engine to the rear axle, with the 12-9x6 Hoosiers on the rear. I don't have a tach, but I don't think I spin my vanny any more than about 8500 rpms.
Again, it's lots and lots of fun, but you have to make sure everything on your mower is tight and right, and when your racing don't go any faster than what you can control. If you loose it, at these speeds, it aint gonna be pretty!
