I have been racing my 2012 Cayman S (987.2) in the Swedish TIme Attack series a couple of years. Advancing a class, I was allowed to use semi-slicks or R-rated tires. I went to my partners at Östra Gummi to get the new tires. We had decided on the Yokohama Advan AO52. We booked a time. I drove right in and up on the lift, and Magnus went to work.
I had been running these Yokohama AD08 street tires in the Club class
The reinforced tire sides take some convincing to slide onto the rims.
But the machinery used today makes it easier.
Then the air pushes the tire in place
Balancing the wheel with a computer and lasers
Rear wheel tire to be replaced next
When Magnus started it was all hand tools. Could take three guys to mount some tires
Magnus inspects all tires before mounting them.
The tire pops into place, it can be loud.
The laser points out where the small balance weights need to be put
Next rear tire coming off, 295/30 R18
This is close to the maximum amount of rubber I can put in the wheelhouses. Every inch counts to get that last grip
They also remove the sticker before balancing it.
Magnus is an old endurance racer, so he knows the importance of the tires from both professions
Cleaning the wheel before the balancing weights
Already time to mount the wheels again.
These wheels are street legal in Sweden
of course, the tread pattern is not optimized for rain
If your tire shop uses a torque wrench for the last pull, you know you works with dedicated professionals.
Backed out and ready to roll
Östra Gummi is the oldest working tire shop in Stockholm. It is situated in the upper parts of the city, called Östermalm.
