Tire size.

[DoubleD76]

I’m new here and just purchased a 21 Mach 1 without the handling pack. Has the Recaro seat option and 6spd. The previous owner put a set of SVE Drifter wheels on it that appear to be 19x11 all the way around. With 285 35 19 nitto 555g2 tires on them. I was wondering if I could put a bigger tire on the back to help the highway rpm cause it’s my daily and I drive 110 miles round trip to work and right now at 75mph on the dash actuall only running 71 and turning 2200rpm which seems a bit high for highway running. Thanks for any info that you could share.

285/35R19 is a bit of a stretch on an 11" wide wheel already. You really should have 305s.

You don't really have a lot of options for taller tires on an 11" wider wheel.

I would suggest getting 19x9.5 or 19x10 square or a Ford Performance Pack wheel set / Mach 1 wheel set to revert to stock. The 5-spokes go for $1k at a few places.

To match the factory tire diameter (275/40/19) with a 35 profile you’d need 315/35/19. I have no idea if that will fit in the fender well, but an 11” wide rim can handle it.

Much better options than the Ford Performance Mach 1 wheel set. They are ridiculously heavy compared to the SVE versions. I sold off mine and went SVE. Saved ~6lbs per wheel
