Re: 255 45 18 fitment?
Depending what you are runnin on the rear, I think these may be taller than your rear tires. 255 40 18 are a perfect match to the stock rear tire. I am running 265 40 18 in the rear which is slightly taller than a 255 35 19 I am running 235 40 18 on the front. My wheels are 8.5 and 9.5 wide. this doesn't look like a good idea.
