3197 was allegedly redsigned over the 3195 to resist chunking and offer more stability for blown/procharger applications up top end

The problem with the 3197 big bubba in TD is mostly on cars running 225 mph in the 1/4 mile, MT engineer even admitted that to me. I could not get more than 25 runs on a set without chuncking and blistering on my blown TD running north of 230 mph. Since switching to Hoosier, first the c1500 then the c1550 I havent had any tire issues, plus they hold air

Look, it's not just one thing. I am not saying there aren't issues as you are seeing either. You obviously aren't taking bracket racing with your deal, Look at TAD, Hoosier aren't allowed on the A fuel cars and GY's chunk too with these combos. At your speeds/HP levels, parts just don't last that long... I have also stated this many times, Hoosier makes a good tire too...
As for your typical bracket dragster, the 34.5 hoosier is a terrible match for this combo, tire shake in the burnout and more issues down track. The Big and Small Bubbas rule. I hear that Hoosier has another tire out that cures the burnout issues, if so that's great for all racers, competition is a good thing.
Either way, good luck with your fast dragster combo!

C1550 but on the typical bracket dragster the BR3 is just as good.

I have a medium-ish dragster, but i’m curious how many runs are you guys trying to get out of tires that you are running 6.10 at 230 mph with? Those speeds seem like something that would really stress any tire and i’m not sure how many runs i’d want to make on the same set.
quote:As far as the Hoosiers go 75-100 runs would be very reasonable IMO. Last year I took off a perfectly good set of 50 run c1500s and put on c1550s for the indy trip. I heard Rusty Baxter once ran his c1500s until the cords were showing and would not hold air but you would have to ask him if its true or not.
I know of a deep pocket very fast Pro Charged TD racer that told me he put 6 pairs of MT3197s on his car last season. He said he has a BOGO deal with MT and doe

you saw my 3197 at indy with the huge bubbles in them...then when the tire cooled down they went away. that was 75 passes but only 25 where over 230mph
