Tire size

[Azera convert]

I own a Genesis 3.8 Sedan that came with 235/50/18 tires from the factory. I’m thinking of putting 255/45/18 on it. The OD is the same, so no speedo issues but it is 2 centimeters wider (appx 1 inch). Has anyone made this switch without problems?

Never tried it, I run the same 235 size on mine. Depends partly (mostly?) on how much clearance, if any, you will end up with between the inner sidewall and the suspension pieces, and/or the fenders. Are you able to get under the car and check, or hold a tape measure between the inner sidewall and the nearest surface and maybe take some pictures of what the tape measure says?

Too old to be crawling under the car. LOL I just stayed with the stock size
