I have a stock 06 300 and want some 19 or 20 inch wheels, staggered and flush with the fenders. What sizes should I be looking for, for both wheels and tires? I just don't know anyone reputable enough to get it from in person.

 

I recently bought a 2006 GS300 with the optional 18"x8" Tourmaline wheels and the P245R40 series tires. Although many probably like it, the ride is pretty stiff. I guess I can drop down to the standard 17"x7.5" wheels with the P225R50 series tires, but I was also wondering about the 16" wheels with P205R60 series tires on the 2nd Gen GS models - will they fit and how much will the ride be softened between each inch of wheel size and taller tires. I'd like to keep with factory wheels and keep tire diameter as close as possible. Any thoughts would help. Thanks.

 

if the ride is too stiff, get a softer tire. the 17" tire that comes on the GS gives plenty of sidewall comformt with the 45 series tire.

 

16 inch will look like garbage on a 3GS. I don't know if it would even clear the brakes.

 

Well the 300 does have the smallest brakes out of the 3GS'
