Bought 2nd hand my new baby has 2 different tyre sizes will this be a problem for the transmission or do i get the seller to change front tyres back to standard the label on door recommendation are 225/40/18 all round

i would of thought originally your car left the factory with 4 tyres exactly the same so if it was me i would  fit them as Audi recommend

David.

You have lower profile tyres at the front which means effectively the overall diameter is smaller, which in turn causes lower top speed/greater acceleration/greater fuel consumption. The lowering of the front end of the car may also have an effect on steering. I would get the tyres changed to the correct size.

Thanks cliff thats something i can share with the garage and hopefully they wont argue over as it could be a safety issue
