Hello,

My car is 330i equipped with the 18 rims named with "4 Spoke 416" with stranded Tyre size 225/45/18 in both wheels front and rear

My question here can I change the rear Tyre size to be more wider than 225 and if yes what is the best Tyre size can be fit in the rear wheels ?

another question is if I changed the rear wheels size only does it affect the speedometer readings ?

If the outer diameter or circumference of the tire is changed then the speedometer reading will change. The best tire size for your car is likely going to be the one that it came with.
