Our rules this year say any 8 inch tire. I would like some info or opinions on the options. How is the dirt boss Hoosier compared to the UMP Hoosier?

I know only one guy who's run both, and he said he didn't feel much of a difference. I would think that it would depend greatly on whether you were allowed to groove/sipe them or not. If not, I'd think the UMP style would be the way to go, being that the tread on those tires has a much smaller block pattern, which would make them act like a softer compound. If you're allowed to groove, it all depends on how they're cut. I've run nothing but the Bozz tires for the 4 yrs I've run mods, and I've been known to spend up to an hour cutting a right rear before I even race it. It takes a lot of experimenting, even if you look at someone elses tires, because the depth of your cuts has a lot to do with how they work too, and you can't tell that just by looking.
The UMP tires don't look like they'd stand up too well to being grooved. They just don't look to me like they have enough tread block mass to afford making them much smaller by cutting them. I could be wrong, but, in my experience, unless you're running a hard compound, you can't afford to make blocks much smaller than 1/2" square. On the other hand, if you're running the hards, they run well with lots of sipes, but not too deep or it'll chunk bad.

I could go forever on this...

We ran the dirt boss for a few years and had real good luck with them after grooving them also. But by the time we found out how to get the right groove in them they changed classes on us and tire. Do you race at St Helens Or.?

We had a rule like this several years ago. We used a McCreary sprint car front with 8 in. tread pattern. Those tires had some bite! Don't know if these would be "legal" at your track, but it's worth a thought.

We are in No. Calif. but we did race in St. Helens three years back. We also raced with dirtracer14 I believe in Elma, Wa. at the Northwest Nationals. $5,000 to win guys come on out in June.

We ran at least 10 tracks last year with wins in Yreka, & Susanville. We broke both nights at Elma. Yreka has new management & is paying $600 to win on the high banks.
