Will the odometer need to be recalibrated with a taller tire on the rear? Or can the car handle the variance?
Is there a way to code for it?


Get a tire comparator on places such as Tire Rack and plug in wheel and tire size you have now and what the new ones are an it will tell you the error.
I gave a set of snows to my son because they were crap on the C63 AMG PP because they fit his Kia Soul which has an odd size. The diameter was slightly different so when his speedo say 100 kph he is actually doing 98.
Easy to get precise info using a tire size comparator https://tiresize.com/calculator/
