Hello,
I want to change c4 cactus shine edition tyres (205/50 R17) to 205/55 R17 because on my country routes & highways are bad.
Do you think car stability and general driveability will be affected?
Thank you everybody for your answers.

It uses a bit more fuel, but the shown MPG will fall some since it is now showing the real MPG.

Im getting 60 MPG, and that is only on small roads with a lot of stop and go.

I think they are more comfortable, no change i noise, noise is largely a tire thing, some are more noisy than others.

Good afternoon,
Interesting this change from 50 to 55.
I just bought my eat 6 with tyres 205 50 17 (just the last one of model 2017; new 2018 is now for sale here in Spain!).
I don't like so much the low height of the tyre and the Good Year but of course I will drive for a while with them.
Going in the future to 55 does that mean that my car will be appr. 2 cm higher, which I prefer anyway?
If so, there will be no problem in the 2 yearly security check? What about the warranty (the company in Madrid told I can't change from 50 17 to 55 16)?
Regards,
Rob
