I was wondering if anyone has converted their cars to a square wheel configuration? For example 19x9.5 on all 4 corners. The 19" Sport Pack wheels are 19x9.5 ET58 with 275/35/19, could that work on all 4 corners with something like 265/35/19 or 265/40/19 for a little more comfort?

After having got punctures (non-Aston car) in very remote places and being very lucky to have a physical spare/donut on hand, I'd like to simplify the wheel configuration on my DB9 in preparation for some long trips and find a Mustang donut that fits or custom make one.

I'd even like to go down to 18" wheels for more side wall if possible. Pretty much the opposite I think most people like to do

 

I live in Northern VA, and drive in DC... I like sidewalls!

 

Did you ever get a response to this? My '07 vantage came with 21s and lowering springs. I want to go down to 19 or even 18s so I can semi daily the car. However most of the aftermarket rims I find have an offset that's much less positive like 30 or 40, instead of the stock 50.3 front and 62.5 rear that mine came on.

 

OEM Vantage wheel sets are pretty easy to find.

 

Your wheels have an offset that push them farther out in the wheel well than factory. If you're at about 35mm offset, you will have pretty flush fitment and be totally fine. In my opinion, the factory offset is terrible.
