Hello All,

A friend gave me two lightly used Michelin Pilot Sport A/S Plus with the following size:
245/40/ZR17 91 Y.

currently my 986 rears are using the Toyo R1R 255/40/ZR17 94Y.

The wheels are standard 2001 "Boxster Design" rims - size 17 x 8.5"

Is there any potential issue of using 245 instead of 255?

Many thanks in advance for your advices!
