Tire change advice

[Wonder]

Hi everyone,
I need to change the tires on my Jazz (185/55/R16 87H). I currently have all-season tires, but I've only done 25,000 km. I use the car mostly in the city, and in winter it can snow (not this year). I only do about 7,000 km a year.
What can I put on them that will allow them to go at least 30,000 km?
I might even go as far as 35,000/40,000 km.
Thanks for the advice.

I don't know which all-seasons you have now, but we have been driving our Jazz on Vredestein Qatrac 185/55R16 all-seasons since new. Now, after 37,500 km, they are still okay.

Toyo proxes Comforts.

Been excellent, great wet stopping power, smoother than OEM Blue earths and definitely quieter too.

Michelin CrossClimate.  They just go on and on.

I would agree that the Michelin CrossClimate tyres are one of the best choices for a combination of performance and extended wear.
Certainly not the cheapest, but there is a lot of info on the web which confirms they have a long tread life.
