Blow out racing a 511 bhp Merc SL55 AMG !

[Jon Luik]

Hi Guys

Just had a 130mph blow out while racing a 511 bhp Merc SL55 AMG !

No major problems just a lot of tyre spoke. The guy in the Merc even stopped to help and we compared notes !

Now this could have been a lot worse and I am trying to find out why.

After checking the tyre wear on the blow out, the outside tread is 4/5mm while the very inside is only 2mm. This is the same on the other rear tyre.

The fronts have 5 mm all round. Currently using Pirelli P Zero’s.

I guess I will have to replace both rears, but how can I stop this un even wear and could it be the reason for the blow out.

Any suggestions welcome.

The uneven wear could be the reason if the inside of the tyre was right down to the canvas. Have you had your geometry checked lately? Sounds like you might be running quite a lot of negative camber. I know GT2s are prone to wear like this, but didn't think TTs were affected.
