I'm thinking about running 275/40R20 fronts with 305/35R20 DRs in the rear. I'd prefer a 35R in the front too, but the tires I'm looking at are on back order in that size. The 40 seems to only be 1 inch taller than the 35. I'm wondering it that will make that much of a difference in looks? I'm thinking it will barely be noticeable.
