A recently imported Toyota Prius Alpha (1800CC) has come with Yokohama Guard iG50 M+S tyres (205/60R16 920 iG50) having peaked mountain with snowflake symbol on these. According to the tyre sellers these are only snow tyres and will not be suitable in Summers and will also have long braking distance on wet roads where as on the net it is otherwise.
I live in Islamabad where the temperature varies from -3 to 45 degree centigrade. I have following querirs:-
1. According to net M+S tyres can be all season but how can I confirm it?
2. Can I use them in summer?
3. Will I get problem in braking on wet roads?
4. will the tyres have as long life as any other tyre (like all weather etc)?
Any friend who can suggest a better choice.
