Perhaps have a look at seeing what both your car and those you might want to change to in a year's time might be able to share from a winter tyre POV - you never know, it might save you some £££ in not having to sell some brand new winter tyres and alloys when you buy the new car.

Or having a look to see if your current car will accept (both physically [watch those break callipers] and from an insurance POV) either smaller diameter, higher-profile as well as the same sized all-season tyres (try looking at the TyreReviews website for an extensive list of magazine tyre tests and of actual vehicle owners reviews). There's a new one out from Michelin called the Cross Climate, which is a bit more biased towards summer performance, but appears to still work well in winter conditions. Might be worth a look if you can find them and at a reasonable price.

I suppose what 'works well' for you may depend upon how bad the snow/ice gets round your neck of the woods and how often - as per my post of 4x4s, driving style can make just as much difference (even with summer tyres on a 2WD car) as what tyres you use.

thank you for the comments

I have visited this site

www.etyres.co.uk/how-to-change-your-tyre-size/

This tyre size seems comptabile

245/45R18 96V

The current tyres are 224/45R19. Not sure how the above tyres are compatibile but the tyre checker say that. I would like to believe it.

Should I ?
