Dear all,
I'm writing from Rome (Italy).
I'm a owner of a A-Class 160 CDI (44Kw), sold the first time in Germay
(1999).

This vehicle has on it's documentation the 155/70R15 as unique approved tire
size.

I saw that in Italy, the most common tire size for the A-Class is the 195/50
R15 82T.
What is the procedure to request a permission for the use of an alternative
tire size, like the 195/50 R15 82T ?

I' ve already contacted Daimler-Chrysler Italy, but they told me that this
variation is not possible, without further details.
I'm concerned about this negative response, because I' m not asking for a
particular tire size, but only for the mostly used all over the Europe.

Probably Daimler-Chrysler Italy doesn't offer collaboration for this kind of
problem because the vehicle was not sold in Italy.
Can you help me to contact the correct center in Germany to obtain the
necessary authorization to use 195/50
What is the documentation required for this request ?
Sorry for my "not perfect" English.

Thanks.
