Another Tire Size Question

[Rayk]

I’ve checked the tire size sticky and don’t find the answer:
Can I run 245/60 x 15 tires on the front of my Regal to match the 245/60 I have on the rear? I currently have 235/60 in front but want to be able to rotate the tires.

My wheels are the GN alloy replica wheels in 15 x 8.

First off, nice looking car.
If you’re at stock height, which it looks like you are, they should fit.
The 245/60-15’s are only 1/4” wider and 1/2” taller.
I know it’s hard to see sometimes, but there might be a way of measuring the clearance on the front to see if you have enough room.
I would put one of the rear tires/ wheels on the front, set the front down on a couple of sheets of cardboard (stacked) to make it easier to turn and check if they clear.
I had 255/50-16’s on all 4 corners back in the late ‘80’s. They were on 8.5” wide wheels with 4” backspace. The fronts rubbed just a little at the top of the fenders over large dips.
On an 8” wide wheel with the same backspacing there will be more clearance at the top of the fender.

Good idea. I hadn’t thought about putting the rear tir es on the front.
