Thread: 255 tires

The rims can play a big factor in that. If a lower offset, they will rub.

A 245 tire is usually what most people run, no real reason to go wider.

Stock 225/55/17 are 26.74" in diameter. 255/45/17 are 26.03" in diameter. 255/50/17 are 27.04" in diameter.

Neither of those 255 sizes are optimal. 245/50/17 is the optimal size if you want to go wider. It is 26.65" in diameter.

Simpler than that...

55% versus 45% ofthe same width. Width is 225mm.

Difference is 10% of 225, difference is therefore 22.5mm in section height.

Near enough to one inch.

Overall diameter has TWO section heights, so overall diameter change is... almost two inches.

I did the math, it is what I said it is.

You can use this to figure out if they fit or not:

Like steathee said they are either to big or to small, the 245/50/17 is what you want.

I'd be interested too if they rub, I'm looking at a deal for 255/40/17 ( ~ 2.5 % shorter) with high offset. I ran 245/45/17 on a set of bullets and they didn't rub. tires were not tall enough.

Those would be way too small, that is only like a 25" tire instead of the 26.7 that a 245/50/17 or 225/60/16 is

FWIW i have 245/45(maybe?)/17 on bonneville rims and all 4 tires rub on the plastic guards. (have 225s in garage but found out left drivers rear rim has a crack, ugh)

I currently run 245/50/16s all around on some Pregens and I dont rub at all.
