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.

If you are interested in trading your 21" OEM wheels and tires for my 20" OEM Sport Techno wheels and tires I would be interested. Please let me know. Thanks.
