different tyre sizes on 19s

[ope126]

the 162TSi Superb comes with a 205/55/16 spare tire.

Thanks for sharing that!
It would seem that the theory of a different "rolling diameter" having an effect on the driveline looks to be incorrect.

As your 205/55R16 spare tyre has a rolling circumference of 78.1inch 205/55R16 Tires, near identical to the 78.2inch in my space saver T125/70R18.

So if ŠKODA is happy to provide different size spares, it mightn't be too crucial for short journeys on the spares in case of emergency...

Also, as a guess the reason why you have a 16" spare tyre and I have an 18" space saver could be due to the larger front brakes in the 206TSI.

Now to find some 245/40R19 tyres...
