Hoosier Track Tyre Blowout

[GTR59]

I have been running 19in Hoosiers R6 295 front and 315 rear for all my track days this year.

The 1st set lasted 3 track days

The 2nd set lasted about 3.5 tracks days.

These days were all about 3-4 sessions am and pm

I checked the tyres carefully after each session - especially the fronts

This was the Left front. - the one most punished at QR

I was just trying to get one more day out of the tyres before switching to 19in Michelin slicks.

I was lucky we didn't go off track or damage the car.

My take home message - Be careful trying to get that extra milage out of track tyres.

Paul Stokell was driving at the time and just got a 56.1 with me in the car on QR sprint track. My best prior to his session was 57.4. After the tyre blew i put my near new Dunlops back on the car and got 57.7. I thought it was interesting that 4 day old Hoosiers are basically the same as the Dunlops.

Interesting post Bill! I'm glad there was no damage to the car. Is the rim damaged?

30 is a very low profile - some tyres just don't work well with low profiles.

glad there was no serious outcome

The rim looks ok so far.

It was funny we were just talking about having a tyre go at the track at lunch time . So I'm glad Paul noticed it on the main straight before he got to turn 1.

Something else, in the previous session, Trent and Paul could here a sort of tyre noise as i went past. Paul was thinking of black flaging me. I thought it was just a marble of rubber stuck to the tyre. I even looked under the front of the car at the insides of both front tyres before that session to see in any canvas or tyre construction was showing through, but nothing was apparent.

Small rub of wire from tyre on upper control arm.

Front left

this was in the middle of the front left tyre - i thought maybe this may have caused a leak leading to the subsequent complete tyre failure.

Front right - fronts are heavily scolliped out on the outer sections of the tyre.
