Best tire sizing

[jamesxnguyen2]

I’m getting the eibach lowering springs soon (1.7 front 1.2 back) and I was wondering what the best tire size would be? I only need rear tires, front ones don’t need change. I was thinking 285/35/19.

It very much depends on what oil you use, and where you purchase your espresso.

I went with 265/35/19 Front and 285/35/19 Rear.

I'm also lowered on Eibach springs but I have an MT and their advertised drop rate for MT cars is -0.9" F and -0.8" R.

If they actually changed the drop amount and that's true, I have no idea as I didn't bother with measuring before/after. Just made sure the drop was equal all around afterwards once the springs settled.

I went with 295/30/19 in the back and 275/35/19 in the front. I am going for 305's next time I change my tires.

Stock wheels, stay with 255/275 for best handling and response but get better rubber…200TW. Rubber gives the most improvement in handling and grip, not size.

For street driving, you want those 200TW that gets up to operating temperature fast and decent in the rain.

On OEM wheels, i went 295 rear and 275 front, i do rub fenders just a bit with spacers on. I haven't got around to seeing if i can remove the spacers to avoid fender rub but then i may run into inner liner rub so meh. I'd probably go 285 rear and 265 front next time around. To each his own on this but i'd prefer not to rub the paint off of the inside/bottom of the fenders. Tires i'm running are RT660's.

on OEM wheels and HKS Hipermax R coilovers, I went with PS4S
265/35/19 F & 285/35/19
HKS Hipemax R, comes pre adjusted height from the factory
-0.9 inches front & -1.1 inches rear

no rubbing issues and perfect grip comparing to stock tires

Stock rims? What size spacers and are you lowered?
