just got myself a punto grande 1.9
with 17" alloy wheels but have no spare wheel what size wheel will fit ???
hope someone can help

Hi
If your 17" rims have standard fitment 205/45/17 tyres fitted
you could use a steel 15" rim with 175/65/15 or 185/65/15 tyres to give the same overall rotating diameter

According to this guide a 205/45/17 alloy will fit.
