Tire dimensions as per regulations:
Max. complete front wheel width: 355mm
Max. complete rear wheel width: 380mm (-1.0mm)
Max. complete wheel diameter: 660mm (-0.4mm)
Min. complete front wheel width: 305mm
Min. complete rear wheel width: 365mm
Wheel bead diameter: 330mm(+/- 2.5mm)
Max. front tire tread width: 270mm
Max. rear tire tread width: no restriction Dry weather tires as per regulations:
All dry weather tires must incorporate circumferential grooves square to the wheel axis and around the entire circumference of the contact surface of each tire.
No. of grooves: 4 arranged symmetrically about centre of the tire tread.
Distance between centres: 50mm (+/- 1.0mm)
Depth of each groove: at least 2.5mm
Width of each groove: minimum 14mm on the surface minimum 10mm in the bottom
Bridgestone dry tire dimensions:
Front tire nominal size: 265/55R13
Front diameter: 655mm
Front width: 335mm
Rear normal size: 325/45R13
Rear diameter: 655mm
Rear width: 375mm
I got this from McLaren's web site, but I think the expression of tire size in street tire nomenclature is incorrect... tire industry uses the sidewall width, not the tread width. Therefore 335/50R13 front and 375/45R13 rear?
