I now have them fitted. No scrubbing. Speedo out slightly (too fast) but just new to be cautious of speed from now on.

If you have a way to measure actual speed, I would be interested in what your speedo reads at 60mph.

The 275/55-20s calculate to be 31.9" tall, and I have a set of Nitto '421s that size on my '13 Limited with QL. They don't rub anywhere, any time. I drive my GC around town in Sport mode which lowers it about a half-inch.

I use a Garmin GPS receiver which indicates speed to the tenth of an MPH. Using that and comparing the speedo' and GPS readings at about 2-dozen speeds, my speedometer is 3.1% slow. That means it indicates about 58MPH at actual 60MPH.

Thanks. That's exactly what I was looking for. On my soon to be delivered CRD, I'd rather the tire be at factory spec diameter or a little larger. Your data tells me all I need to know.

With the tyres I have in aero mode at 110 kmh my Tom Tom GPS reads 113 kmh. So I am slightly 3 kmh too fast
