Tire sizes

Hi Guys

I finaly decided to go with 17" wheels for my 147 2.0. In the manual I saw that they reccomend 215/45 tires. The weekend I saw a 147 with 17's fitted with 215/40 tires. It looked great. Is there someone that can tell me if this will affect my speedo and other things. I know that the ride will be much smoother with the 45's but the 40's looked sexy.

Re: Tire sizes

215/40R17 are the wrong size.
Too small in diameter plus the load index of the tyres will be too low (ie they not strong enough)

Stick to 215/45R17 "W" rated and at least 91 load index (which probably makes them "XL" too)
