2014 640i gran coupe tires advice request

[amjaad1]

Hi all I am planning to remove all of my run flats out of my 640i gran coupe and put regular tires and buying the mobility kit with foam. I checked most of the shops here in my city and they did not have the exact tire sizes I am looking after. The car specifies the use of: 245/35r20 for the front 275/30r20 for the rear However, I found 245/35/r20 for front 275/35/r20 for rear With a difference on the rear tires only. So, my questions before doing so. 1- is it ok to do this with no problems on the car. 2- could this void the warranty on the car? thanks

Hello and welcome to the forum! I don't think that you'll have any issues with those tire sizes and this will not effect the warranty. Please let us know if you have any other questions!
