Go 275/50/15 you'll do better with a 26" tall tire compared to a 28"

Iirc the back spacing for 15X8 is 5.5" and 15X10 is 7.5" been a while since I looked it up. You will have to run a spacer in the front for 3.5" wheels and grind the cooling fins off the rear calipers. Stay with a 26" tall tire, 28" will reduce your gearing and require rolling the fender lip and isn't needed at the power level.

275/50 is probably a better bet for a stock/bolton car.

I ran a 255/50 on my bolt on car and had no issue cutting 1.6 60's. Same thing with a 275/50

sometimes lack of spacers is indicative of worn brakes or a faulty caliper

275/60r15 for me. Haven't rolled the fenders and haven't had any rubbing so far. Stock ride height.

On mine I had passengers in the back while running the 28s and drove around some. Heard a flapping sound and realized the fender lip had cut a chunk out of the edge of the tire all the way around. Not saying it will happen to everyone especially if you never load up the hatch or rear seats but it has to me and others.

Take out the back seats and don't worry about it .
