I bought a set of 20" wheels used from this forum off a DB9 a while ago and had Tire Rack installers out yesterday to change the wheels and tires out. I was in Naples and not in Minnesota where the car resides. They said I have 21" rears and 20" fronts so I ordered 305/25/21's PS4's to return the 20"'s. I had 20" wheels on past Vantages I've had - they look great - not sure I every saw 20" front 21" rears. Anyone have similar? Won't get them installed by Tire Rack mobile till next week. By the way Naples has more Astons than any other city I've been to.

 

Your probably the only one. My friend had 21" monoblock HRE on his 08 morning frost. Looked great with a 1" difference you may not notice between F-R. You have them and are making them work so shouldn't be any issues.

 

The tires I ordered are both around the stock diameter (sort of) 245/35ZR20 PS4S and 305/25ZR-21 Michelin Pilot Sport 4S will post pictures after the install on Wednesday.

 

I swapped out my DB9 19" stock wheels for aftermarket 20's and really wanted to go to 21's on the rear but the wheels were not available in that size.

Looking forward to your pics to make me jealous.

 

I'll post pictures in a week after they are installed. To keep the 27" diameter, the 305/25/21's sidewall is not so much, but hopefully because of the PS4's it won't be too harsh, something I can't tell till spring after the streets are clear.

 

I have 20/21” wheels on my 992 but that’s how they come from the factory. Too big IMO

 

This is what 20's in the front and 21's in the rear looks like on a V8 Vantage:

 

Looks great, nice silver classic 5-spoke design.

 

The size difference is definitely noticeable due to the different tire sidewalls. But wheels themselves look great. Brushed clear, I'm assuming?

 

Yes brushed clear - I think the side wall difference (stock diameters) might be ok but won't know till spring after snow melts and roads are washed clean by rain.
