What size tires are recommended for 19 inch AMG wheels

It's best to use an online calculator. Input you're existing tyre size (215/65/16 probably), input the new wheel size and it should tell you the best size to buy without having to recalibrate the speedo. For example if you have 215/65/R16 tyres fitted now and you wanna fit 19 inch rims then a 255/40/R19 would give you 0.25% larger overall tyre diameter. This would mean that you're speedometer would read 50mph but you're actual speed would be about 48mph.

I have a mecedes e class benz 1998 what type of tyre should i put onto a 15 inch rim.
