Anybody switched their tire size from 255/55 r18 to 275/55 r18? Any difference in handling?

You would probably need to go to a 275/50 r18 in order to maintain the original diameter, otherwise your speedo and odo would get thrown off. As the poster above said, you can give Tire Rack a call for advice.

Most folks who come here realize that a 275/55 is a totally different size / diameter than a 255/55. First, the 0.9" difference in diameter is going to screw up your speedometer, odometer and gearing. Second, the increase in diameter and increase in width may very well cause clearance problems with your fenders, particulary on your front wheels, when turning. Third, the 275's are designed to be mounted on a wider rim, meaning you are changing the overall tire geometry, likely leading to sloppier handling.

As others have said, seek professional help before you try this on your own.

I had Michelin Latitude Tour 275/55R18 on my 2011 x5d for about 2 blocks, the tires rubbed on the suspension just above the tire on the inside. It was not touching until I turned, never drove over 15mph to see how bad it would get. Went back to Michelin Latitude Tour HP 255/55/R18 none run flats this time. Good Luck
