What is the recomended tire size for 20's on the F50? 245/35/20? is it possible to fit 245/40/20 on the wheels for added comfort/protection?

245/35/20 is a good size to go with. I actually have 255/35/20 on my car, but plan to drop down to 245 when ever these tires wear down.

Thanks for the feedback. I was thinking that 35 series tires are somewhat thin considering the size and weight of the Q45, and thought upsizing to a 40 series tire would give the Q a more comfortable ride quality.

The main thing that you want to make sure of is if the tire that you are purchasing meets or exceeds the OEM load rating. On my car, the OEM load rating is 93 I think. But the tires that I have on my car now has a load rating of 97Y so I'm ok.
