It's summer and...

A recurring topic, I know, but have you recently found summer tires (215/55 17R), wiich really feels quiet on the Avensis?  Reading user or test reviews on the net is useless. You can be sure 50% says a certain brand is very quiet and the other half it's noisy as hell. I know it's an individual thing, some dont care and dont understand the problem, other are allergic to every noise leaking into the cabin.
Myself I have used the Goodyear Efficientgrip Performance one a couple of Avensises. They are allright I guess when new, but becomes rather noisy after 2-3 years. Someone out there must, by trial and error .. or by sheer luck, have found some comfortable, soft and quiet tires?

The EU ratings for tyres provides a basis for choosing your tyres. It gives a tested rating for each manufacturer's range of tyres covering three categories: fuel efficiency, wet grip and external road noise. The ratings range from A (best) to G (worst) and external noise is measured in decibels. However, these ratings don't cover every aspect of tyre performance.  An explanation of the tyre ratings system can be found in this link https://www.national.co.uk/information/complete-guide-to-tyre-labelling

In the case of tyres I prefer to use the EU ratings together with expert reviews rather than ad hoc anecdotal recommendations.

According to Goodyear, as regards fuel consumption ratings choosing an A rated tyre instead of a G rated tyre, may save more than 6 litres of fuel every 1,000km.

So if you choose an A rated tyre over something like a B or C rated tyre, the fuel saving will be less.

The difference between the A and F ratings in the wet grip category are in my view more crucial. For a passenger car applying emergency braking from 50mph, a set of A rated tyres will stop up to 18 metres shorter than a set of F rated tyres. In an emergency situation even a few metres could make the difference between life and death.
