2008 1.8 Tyre size - cindersifter
In the road test it states that the 18" tyre gets more of a bump from potholes and bumps than the 17", and also that the 16" tyre is the least affected.

I always thought that the bigger the tyre, the comfortable the ride.

Could someone explain please.

2008 1.8 Tyre size - Peter D
With the increase in rim diameter the tyre profile is reduced to retain the tyre outer diameter and the speedo calibration For example 195 55 16, 195 50 17 and 195 45 18. The sidewall is much smaller on the latter and makes the car prone to pot holes, cats eyes etc etc. It's al a case of balance, no pun intended. Regards Peter
