I just put 20" DBS wheels on our V8V. I had the 19" wheels set at 33 front and 34 rear. I was wondering what the 20" tires should be set at. I did a search but found nothing.

 

What brand tire are you running? I'd start with 33/36, factory spec pressure for your 19"'s and see how you like them. I run 35/37 in my 20" Michelin Sports and 36/38 in my 19" PSS which is the factory spec pressure for my DB9. As you know here in FL tires warm up pretty quick.

 

The tires are Pirreli P Zero 245/35/20 front and 295/30/20 rear. Same size tires and brand that is on our 911 but I know different cars will have different specs.
