Michelin Premier LTX question

you just need to understand Tire sizing better. It's the overall diameter and the revolutions per mile that matter to the speedometer. You don't need to have it programmed. Instead you maintain relative similar overall rolling diameter. Google up a tire size comparison calculator. If you put in 275 50 20 and 255 60 19, you see they are very close in overall size despite the differences. Anything within 3% is considered pretty much the same.

I'm considering 275/55R20 tires since there are a lot more options.
Real speed will be 62.1MPH when speedo says 60.

As mentioned by MBQureshi above, the Michelin Premier LTX tire tread depth starts out a 8/32, or 8.5/32 according to Michelin themselves. Almost every other tire tread depth starts out at 10/32 new, so you're effectively losing out on 2/32 usable tread right from the start.
