unusual tyre wear?? on a giulietta

[cc]

Hi guys
Would a front passenger tyre wearing out to a point it is replaced, while the other tyres are still very good.. be unusual?
Its a 2015-ish Giulietta 1.4L (not sure of the year)
A new tyre is being fitted.
The old tyre was 18 months old with 30,000km on it.
I was thinking having 2 wheels of slightly different diameter on the front may not be ideal..
cheers CC

Yes, unusual.

Are you having a full wheel alignment done when the new tyre is fitted?

Ideal, no
Also illegal I think

One of the cheapest improvements is having correct tyre pressure and also correct wheel alignment for Australian road conditions - the roads you drive on.  The difference is noticeable.
