Alfa 147 16v JTDm

[superpp]

I'm taking my 147 across to Germany in the New Year (now living over there).
Looking at a set of winter tyres for it at the moment.

The manual says to fit same size (currently got 17" alloys with 215/45/17 normal tyres).
Planning to get a steel rims but not sure what size to get, forum searches say to fit 185/65/15.

What size should I go for, does the smaller wheel affect speedo readings etc..?

That size is pretty spot on... http://www.miata.net/garage/tirecalc.html

So long as the rolling radius and particularly the offset is about the same, you'll be fine.

cheers for the info, 185 looks like the size to get.
