Any ESP issues w/ 10 mm wider front tire?

Thinking about running a 255/40-19 instead of the factory 245 on my '05 CL65. Never had any issues with much more substantial circumference changes on my other cars, but the sales rep is convinced that I will run into ESP issues.

We're talking about a difference of 0.3" in overall diameter here. I can't imagine that this is an issue.

Thoughts? Experiences?

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.

4/10 in wider

3/10 in taller,8 revs per mile fewer.All pretty much in the range of just some different brands measurements for the 245/40/19's so no it won't make a difference.Your distance traveled per the same engine rpm will be 56 more feet.In 5280 ft. that is what about? 1%

I did not have an issue with the esp but make sure you current tire is not too close the the portion of the suspension that actually curves out over the tire. Had an issue with larger rubber rubbing on this and groving the tire. The tire that matched factory on mine has very little clearance and an additional 4/10" may be enough to make it rub on turns.
