When departing from 20 inch rims, a popular combination and being on the wide side seems to be:
Pirelli Tire 315/25-22 back and 265/30-22 front
These calculate to a 3.15 sidewall front and rear
What are people thoughts to this combination?
Pirelli Tire 315/25-22 back and 285/30-21 front

With these fronts, the sidewall increases to 3.4 (about inch more)
It may not be much, but Im wanting a bit more in the front for our winter pothole season, plus it provides at least .6 inch more tread in the front for extra grip.
The fronts will be .4 shorter than the rears, which I belive is withing the margin.
Anyone run such a combo?
Any thoughts?
Id consider 20s in front and 21s rear is someone made those sizes within thin the same tire model.
(Looks like any decent wheel is a custom size anyway, so might as well match to the tire size I want.)
