Quick Question for the Tire Wizards

40 to 332 · 05-17-2021, 09:46 PM

Car is a 2013 Coupe w/Sport package. Equipped with Eibach sway bars front and rear, coupled with SPL endlinks. All stock suspension otherwise. Wheels are Advans ... conservative fitment ... fronts are 9.0 x 19 +35 ... rears are 10.5 x 19 +25. No spacers. Currently running Michelin Pilot Sport 4Ss ... 245/40 R19 in the front and 285/35 R19 in the rear. Rears are nearing the wear bars and need to be replaced. Considering up-sizing to 255/40 R19 in the front and 295/35 R19 in the rear. Suspect there should be no rubbing or other issues, but looking for confirmation from those in the know. Input appreciated. Thanks in advance.

Far as keeping the tire height in check. You're good. Only 0.3% difference. 27" and 27.1"

For rubbing. That's someone else's ballgame.

Nowhere close to rubbing with those sizes/offsets and stock height. Consider adding spacers. That fitment is really sunken in the wheel wells.

255/35/19 & 295/30/19 might be a bit better.

With those sizes, diameter is exactly the same (26"), sidewalls will be 3.5" all around and circumference would be 81.7" & 81.5"

w/ 20mm spacer all around, they'll fit the wheel well perfectly.

At stock height, the shorter diameter would make the already big wheel well gap look huge.

True, I did not take into account that I'm dropped a bit.

I really like the mags on your Z.

Those are the wheels you got with the 'Sport pkg.'

I like them too.

Thanks
