Question on Boxster Wheels

[molecules]

Can I use 235/40/18 and 265/40/18 on my 2003 Boxster ? It now has 225/40/18 and 265/35/18

Those tire sizes are very close and should fit. How ever if you have them installed check all clearances from the tires to the body before driving. Also the larger rear tires will change your overall gearing, engine RPM to road speed. You can go to most of the tire makers sites or the Tire Rack site to check the dimensions of different tire sizes.

If you are using oem wheels those sizes will fit fine, but in addition to the warnings Nick stated the 265/40 will slow acceleration due to the taller diameter.
When my 225/40s wear out on the front I plan to go to 235/40, but will stay with 265/35 for the rear.
