Tyre size should not create any problem.
Did they maybe damage the compressor when they lifted the car?

No, the compressor is working fine, we did check that whit the scanner. but one time I heard a sound that the one traction control do when is activated. also check the string wheel angel and also seem to be working fine. any idea of what els could it be???. I don't want to be a victim dow hire of our only RR dealership. thanks for your answer at least now i know that the tires are not the problem.

Can you scan the trouble codes again? What are those codes?
I will and let you Know.
Dos the tire size change matter? There is only a difference between one size and the other of 10 mm:

Tire size has no bearing on operation of the suspension, aside from possibly limiting travel, and causing extended mode, but your difference is no where close to enough to cause that.

No, it shouldn't matter, although the stock size of the 19" tires on the Sport is 255/50R19, not 255/55R19, so by upsizing to 255/60/19 you really increased sidewall height by about 1" / 25mm or so - about 2" in overall diameter - compared to stock. Still, that change alone is no reason for all those errors to pop up. Have you checked to make sure all four tires installed match in size?
