Hello Everyone,
I'm not happy with the ride with the stock 21" rims and tires on my GTS... Some of the roads in my area are in bad shape.
I was looking at dropping down one size to a 20" in rim and was curious to know if a 305/50/20 sz tire would fit without any issues.
The tire sz on 295/35/21 Thanx

Porsche-approved tire and rim sizes can be found here.
It appears that the largest approved 20" summer tire size for a 2010 GTS is 275/40-20 on a 9J20H2 rim
For some reason they approve one 20" winter tire, but no 20" all weather tires for the GTS.
