Has anyone put wider rear tyres than stock on their car? especially those of you that have made performance modifications such that possibility of wheelspin in lower gears increases.

As stock, my DB9.2 has the following:

245/35/R20 Front (20x8.5" wheels)
295/30/R20 Rear (20x11" wheels)

According to this site (https://tiresize.com/tires/Aston-Martin/DB9/2014/Volante-Convertible/) the 11" wide rear wheels could also take 305/30/R20 (shown in green). I see that 315/30/R20 would also fit an 11" wide wheel.

The Vanquish II has:

255/35/R20 Front (20x9” wheels)
305/30/R20 Rear (20x11.5” wheels)

So relative to a DB9.2 (below), Vanquish II wheels are 0.5" wider (both front and rear) with tyres 10mm wider (again, both front and rear)

245/35/R20 Front (20x8.5” wheels)
295/30/R20 Rear (20x11” wheels)

Is there sense in a DB9 having slightly wider tyres if having been modified to meet/exceed Vanquish II torque & power numbers?
