Ok guy’s I know this tire thing has been talked about a million times but I need some info on this problem I’m faced with! Ok here are my rules.

1. Eight-inch (8") to 8.75 inch wide wheels only.
2. Spacer or adapter, or offset wheel, or combination of the two allowed but cannot exceed two inches total offset per wheel.
3. May use bead lock on right rear only and it cannot make the wheel any narrowed than 8” and no wider than 8.75”.
4. Bleeder valves are not allowed.
5. Tires may not exceed twelve (12) inches from sidewall to sidewall.
6. No studded, knobby, or mud and snow tires.
7. No variance!
8. Racing tires ok.
9. Street tires can be cross-grooved.
Most guys are using Hoosier Dirt Boss with 11.3” section, 8” tread, and 86” roll out. Some IMCA guys who come down and race with us use American racer the same as the Hoosier but with only like an 82 to 84 roll out I think. There are also a few who use street tires grooved, but not sure which tires they use. The thing is they all win races with each set of tires. It seems the Hoosier do better on the tacky nights and the American Racers do better when it go’s dry and slick. The guys who run street tires seem to do good either way.
My question is I found some street tires 295/50/15 with an 11.8” Section, 10” tread, and 86” roll out. There are also a racing radial pretty soft and cost like about $50 cheaper then the Hoosier, and $25 less then the American Racer. Would these be as good or better than the racing tires? Or would these not compare to a racing tire?

The Hoosiers Dirt Bozz is awful hard to beat. I ran Street tires last year, there is no comparison, the Dirt Bozz stick so much better.
I buy the med. compound and find them to be very durable. They are expensive, but they are worth it in my opinion.

I know that the Hoosier a very good racing tire. I was originally going to buy them, but I did some shopping around and found these wide tires. I just wanted to see if they would be as good as the Hoosier or other racing tires. Being 2 inches wider in tread I thought they would have more tire on the surface and grip just as good.

When you used a street tire did u use the same size as the Hoosier? What type of street tire did you use? Did u groove and sipe your street tires? Thanks again!!

With the street tires I ran Kelly Chargers, Firestones GT + 4 and Goodyears, all brand new. I tried siping, couldn't tell the difference, so i stopped. On the RR tires i was able to get about 91", that made it easy to adjust stagger. I do different than a lot of guys. I would use a 245/60 on the LF, 255/60 on the RF, 255/60 on the LR and 275/60 on the RR. In heat races with a real muddy track I would put a 255/60 on the LF too to help plant the RR. I saw a lot of cars with 255/60 on the left, 275/60 on the right no matter what.
You won't believe the grip that Dirt Boss has. BTW it's a bias ply, not radial. Maybe you can borrow a set in hot laps. I have no plans to ever buy another street tire. Like i said i have been buying the medium compound, all the other cars are on the soft compound. Next year I'll get Soft Compound too.

The Hoosier Dirt bozz.....do they have much of a sidewall to them? I have run the RC3's and the sidewalls are paper thin! One lil rub and you are in the pits putting another $110 tire on your car.

When I ran stock cars we were forced to run street tires. Here's my OPINON on that. If your running to the grocery store in grandma's caddy.......street tires are great. But if your racing......use a racing tire. You don't buy a baseball to play football with do you????? Forget about street tires.

they have a single ply sidewall vs a two ply on street tires so dirt bozz is more vulnerable. the dirt bozz will get you nearer the front and usually pay for the cost diff in prize money winnings.

I guess I have the answer I need. I just figured with the grooving of a street tire and a wider tread it would be more comparable to a racing tire. I guess I should just fork out the cash and stop being so cheap!!! Thanks again guys!!!
