At Tyres.co.uk, you'll find Michelin Pilot Sport 5 in 245/40 ZR18 (97Y) XL and Goodyear Eagle F1 Asymmetric 6 in 245/40 R18 93Y for 2017 TT Sport models. You have to check exact factory size, load index, speed rating and any necessary specs against your Reg before placing an order.
The Audi TT tyre size placard is on the edge of the driver's door. The placard states approved sizes and pressures for tyres, and the exact specifications for the wheels and tyres are located on the current tyre and the vehicle handbook.
Audi TTs do not always require all four tyres to be replaced. Two matching wheels may be fitted to one axle. However, quattro version Audi TTs require all four wheels to have matched rolling circumferences and similar tread depth, so replacing all four may be required. If only two wheels are being replaced, then according to UK safety standards, they should be fitted to the rear axle.
