Winter tyres in the summer

Ah, the annual winter tyre bunfight. Watch this before joining in.

Then, a quick follow-up of the M3 versus a summer-tyre-clad AWD:

On the rear i have 0ne M&S and one Conti premium contact 2 and during normal driving and pouring wet motorway conditions i don't notice any difference. "Here comes a load of posts after me putting that" Hahh, T.

As soon as the ambient temperature drops below 7°C you'll only be able to spin round in tight circles...

Interesting to see in Troon's second video that even when the 4WD did manage to make it up the incline it didn't have much control over the route it took, whereas the M3 was able to steer around the parked lorry.

That lower Auto Express video covers it well - especially the wet weather braking.

I see several comments about Continental tyres on here, & i cant let this go unsaid, a near neighbour of mine wi a brand new Peugeot had Contis on from new, once they were a year old they started losing pressure, as iv a compressor hes round to me about once a week, after a while (cos im now getting ****** off wi having to stop what im doing to blow his tyres up) i decided to do checks & it was the tyres had become porous, so i told him to ring Motability & complain, they had em changed (Conti again !) Prob solved ? Yeah, for 1 year, now theyre doing it again !! Its put me off Contis for life !

Winter/snow/all weather tyres derive their extra grip in cold and slippery conditions from several factors.

1. High silica tread compound that maintains its elasticity at low temperatures

2. Unidirectional tread pattern with staggered block patterns

3 Multiple sipes on the tread to cut into the road surface.

4 Deeper tread depth.

Much has been made of the problems of running winter tyres in the summer. This is a misunderstanding of the "performance envelope" of these tyres. A good parallel would multi-grade oil specs. Comparing say a 10w40 with a 0w30 There will be temperatures at which each oil will possibly perform better but there's a huge area of overlap where both will perform adequately. Taking into consideration the range of 24 hour temperatures experienced over a year in the United Kingdom and annual precipitation [ rain /sleet / snow] then the performance envelope of winter tyres averaged out all year round [ and that's important] fits the UK climate better than Summer tyres. There is a geographical aspect to this of course with the "fit" making more sense the further North you go.

here we go

It's not my opinion, it's the tyre manufacturers and German Govt. opinion.

My comment wasn't directed at you DM. It was a humerous general statement about the direction that a 'winter tyres' thread always goes.

I know.

Official advice is that Winter tyres don't work with less than 4mm of tread so have to be changed...

We then buy them and proclaim they will drive up the glacial mountains commonly found in Kingston and Surbiton....
