Frequently asked
What tire size does a Polini 911 GP5 use?
GarageDex's powersports data shows the Polini 911 GP5 runs a 90/65-R6.5 front tire and a 110/50-R6.5 rear tire.
What do the tire numbers mean?
A size like 90/65-R6.5 reads as tread width (mm) / aspect ratio (% of width) - rim diameter (in). Match all three so the tire fits the rim and clears the swingarm and fender.
Can I fit a different tire size?
Stick to the stock size - it's matched to the rim width, speedometer, and handling. A wider tire can rub the swingarm or fender and throws off the speedo, so only deviate on a shop's advice.
