Tyre size

Post by KWT2GG »

Hi:
I have an S90 T6 and having trouble with the too low profile tyre (255-35-20).
what is the highest tyre size I can fit?
i.e. will 255-45-20 fit without scrubbing?
Thanks

The sidewall height on the 255-45-20 is: 255 mm * 0.45 = 101.75 mm..
The sidewall height on the 255-35-20 is: 255 mm * 0.35 = 78.75 mm.

A difference of 101.75 mm - 78.75 mm = 22.5 mm.
Is there enough clearance for another 22.5 mm?

The true speed would be 7.4% higher then the speedometer unless you get the speedometer recalibrated.
