Never had any issues with MT until the last batch of 3197 and they chunked after 6 passes. Gonna try them again but have purchased Hoosiers just incase.

It is too bad MT has continued to have the chunking problem. They are a great working tire but seems like 215 is the top end before chunking becomes a problem in short order. Cars below that range seem to be able to run them forever with no problems. Put 80 passes on my Hoosier C1500 with no problems (had to make a pressure adjustment, 6psi MT to 4.5 Hoosier) and change how I loaded the tire on marginal tracks (MT pull timing right away if needed, Hoosier hit it hard for a fraction of a second then pull timing). Have a new set of C1550 fir this season but the C1500 I hd were still working great.

Regarding fast TD and I am referring to cars running north of 220 MPH the 3197 has a very wide tuning window and will hook down a dirt road. But what good is that when they wont last 25 runs without blistering and chunking?. The Hoosier c1500 has a narrower window especially on a cool race track, I cant speak for the 1550, at least with my car they do, so you have to pay attention to your set up and adjust accordingly. I can live with that if I don't have to buy 3 sets of tires a year

steve what was the least amount of wing angle you used with the MT

My wing is typically in the 1-3* range depending on track conditions. The only time I can recall having more was at Tulsa D4 race, the track has a pretty good bump in both lanes around 1000ft and would really upset my car, adding wing really helped it

Watching a video posted of TD in another thread, it sure looks like most are leaving completely hooked and tire wadded for the first 4 feet or so, then the tire gets round and stands up, I imagine with some wheel speed. Is that accurate?

Yes that is a pretty good description with the Hoosier tire. The MT bubbas acts completely different. When I switched to Hoosier I had to slow the shock extension down a bunch and it still crushes the tire pretty good

Outstanding and helpful slow motion! Thx
My combo is kind of unique right now, and I'm struggling to find exactly how it likes to leave. Staying away from shake became pretty important to me after having to break out the welder. But I need to keep playing with it to get that 60' down.

On a dragster, is there a general rule of thumb of when to use a little vs big bubba? Is it all car weight, ET? Is there a migration right now to the Hoosier new compound? Eventually I need to switch to a 16" combo. Historically I never liked to over tire a car. But going faster may be another story now.

when i use to run those tires, i went back to the little ones cause they werer quicker and faster.... and smoother... went as quick as 6.15 in the 1/4 on the little ones and won a national.... but like the big ones they wouldnt last

Thank you,
I wish Hoosier was offering a smaller version of the 1550. Heck even a 15” rim version
