I don't worry about age, only tread wear. After a certain amount of wear, the fine ice-gripping surfaces wear off. With more wear, the harder rubber substrate of the tire comes to the surface. At that point, I really notice the difference on ice. They are still better than all-season tires, but nothing like new ice/snow tires.

Some say to replace the tires because the rubber compound starts to harden en you lose some of the grip provided by that soft rubber. This is just not something the manufactures actually states. Something everybody here does agree on is to replace winter tires with less than 4mm tread (for winter performance).

Some people want to squeeze the remaining life out of the winter tires by driving from 4mm to 1.6mm (legal limit) in summer. A quick calculation of increased cost in fuel tells me it's cheaper to just toss them and put wear on the summer tires. It also performs poorly in summer...

In the UK there is an upsurge in 'cross climate' tyres. Good in fair wether and foul.

I have not tried them at all but many people report they work well.

I suspect they are neither fish nor foul or jack of all trades and master of none but the UK does not get the extremes seen elsewhere in the world but conditions can quickly change, good to bad and bad to good so it avoids constant tyre changes.

Thoughts?

Dear me.... it has been SO long.... I forgot we use to have to change over to ‘snow tires’. We’ve been in FL TOO long!

I suppose the question is: how deep does that hardening go? I have no hard evidence on that, though my tire guys say it is only skin deep -- as soon as you run on clear asphalt or concrete, the hard skin is worn off.

I have done that on occasion. As you say, there is a cost in fuel efficiency. Handling is affected also, though not so much that a capable driver cannot compensate. It helps to increase the tire pressure to the maximum listed on the tire itself. Still, it is a compromise, and from a survival point of view, tires are a terrible place to compromise.

I agree, the changeover is an unavoidable nuisance.

Watching the news, though, it does seem that nature regularly tries to wash FL back into the sea, which I imagine has its own attendant nuisance factor...? whistle

EDIT: Though I'm responding to a little friendly chaff with a little chaff of my own, I am also mindful of the impact of Hurricane Michael. Hope everyone is staying safe out there.
