Tyres.co.uk offers Michelin Pilot Sport 5 (91Y XL) or Goodyear Eagle F1 Asymmetric 6 (87Y) in 215/45 R17 for the Toyota GT86 across the 17-inch factory fitment. If your vehicle is modified, you will need to check the size and rating against your tyre-and-loading label and vehicle registration.
Every Toyota GT86 contains a tyre-and-loading information label on the driver’s side door frame, visible when the door is opened. This label has the original tyre size, the load and speed rating, and the cold inflation pressure. This label is the most reliable guide, especially where aftermarket wheels are fitted.
Because the GT86 is rear-wheel drive, all four tyres do not have to be replaced at once. Toyota states that all four tyres must be the same size, manufacturer, brand, and tread design; if fitting a new pair of tyres, the UK tyre safety guidance is that new tyres should always be fitted to the rear axle.
