Hi everyone I'm new to the forum

I have a 2013 Cayenne S 4.1d , my cars running the 21" Turbo alloy wheels

Ive been offered a set of 23" wheels that where fitted onto a Bentley Bentayga , Tyre size is 295 / 35 / 23 and offset is Et 20

After reading up its saying my wheels are ET50 , will these not or if they do cause a problem, Thanks
