305 Rears and 275 Fronts with 10mm Spacers and H&R Springs?

JRamM6 · 01-18-2024, 01:28 PM

Need to get some new tires, caught a nail in a front tire and the rears are shot anyways. Wanted to go PS4S 305 in the rear and 275 in the front but I'm running the 10mm IND spacers and H&R springs. Anyone have any experience here? Do I have enough room without anything rubbing? Thanks!

I could be wrong, but I would go with the wider tires and remove the spacers. I would bet they would rub though.

The stock wheels are 31mm offset front and 19mm rear.

I'm running 25mm front and 18mm rear with 285/35r20 and 325/30r20 tires, so my setup is:

Front: 6mm further out from the offset, then 5mm further out from the 10mm wider tyre - so I'm 1mm further out than you

Rear: 1mm further out from the offset, then 10mm further out from the 20mm wider tyre - so I'm 1mm further out than you as well.

As such I think you'll be fine and I think that my offsets sit really well on the car - mine is at stock height though.

Mine's totally stock setup other then 275 up front with 305s on the back; fitment is perfect, I think.

The front tires rub a little on the wheel liner during 90-degree turns at parking lot speeds, but it's no big deal.

I love the look. Rolling on giant marshmallows!

On the rear I run 315 with 10mm spacers no rubbing.

When I had 275 up front I didnt love the look with or with out the spacer. Happy with the look of the 265s and 12mm spacer.

I have 10mm spacer in the front and 12mm spacer in the back.. and I just put the new tires on 275 front 305 back and it's rubbing in the rear.. have not noticed the front yet and its mostly happening when Im turning I think

only rub when I make a big turn normally at the parking lot
