UK Insurance Companies / Brokers / Underwriters used to have this lower speed rating of Winter Tyres for winter being acceptable.

 

Then when you ask what is Winter is it November to March they have no idea. 

It is the end of April and there has been snow in parts of the UK or just sleet and road temps / Ground temp at 0*oC and lower last night.

Now people keep on All Weather / All Season / M&S or even Snow Tyres all year in parts of the UK, 

as long as with enough tread, the load rating and a high enough speed rating they are legal tyres. 

As to what Insurance Companies, Brokers, Call Handlers or Underwriters understand, safe all Weather Tyres are quite likely safer than a ECO tyre one Speed Rating higher on an icy or wet UK road.

Air temperatures are not always a good idea of Road Temperatures and how softer compound All Weather / All Season tyres might be getting 

treated on good road surfaces at UK NSL's.  Speed & Load rating is not just about straight line, but cornering, and side forces.

By your Vmax+25% requirement, a V rated tyre is still adequate for a vehicle with a manufacturer calculated Vmax of 119mph.

 

Ah, OK, see now, totally agree, plus the likely advantages of stiffer side walls, better handling, braking (squirm etc) ... why Skoda chose W rated for the Yeti I'm not sure, and defo price and availability will be a factor at factory gate price but they will have had a reason ( typical use, off road, autobahns etc are likely to feature.)

Personally would never run a tyre that matched the Vmax of the car, I'd always go +25% ..... belt and braces and all that..... just me 

Just another thought on this tyre nonsense. 

 

Why aren't tyre manufacturers obliged to tell us how much tread their new tyres have? 

 

That is certainly a selling point to me. 

 

I looked at 2 tyres yesterday. Both around £130 each both very well known makes. One had 11 mm tread, the other only 8mm? 

 

Just interested.

 Pity you don’t live nearer as I have four tyres I took off the car when I’d only done 2k to put on CrossClimate’s.  They’ve been stored correctly and I’d intended to change them out when I sold the car on.  That event has happed earlier than anticipated.  You’d have been been welcome to have them, not looking for any money just want them to go to a good home.

8mm is the usual depth of tread.

11mm seems a bit chunky what type of tyre was it?

Interestingly, the set I want to dispose of, Goodyear Efficient Grip 225/50R17, I’ve just measured at 7mm, minimum, of tread.

Pretty sure it was a Firestone.

How do you rate the cross climates? They are what I plan to replace my front tyres with (and when the rears wear out I’ll put them on the rear too).

The CrossClimates have proved to be as good as the advertising.  I’m very impressed having initially gone down the summer/winter tyre route the CrossClimates have been excellent.  They give good grip in all conditions that I’ve experienced and seem quieter and slightly more efficient.

on the new Subaru XV, that I’ll pick up today, I’ll change the OEM tyres to the CrossClimate SUV version.

That's very generous and decent of you. Thanks. 

 

Sure somebody closer will take you up on them.

There also isn't a "wear rate test". I've reported this point multiple times, but I find that Dunlops wear about 1.5x faster (mm tread wear per 1_000 miles) than any other make I've used without actually offering better dry grip or aquaplane resistance.

There is a UTQG quality rating showing treadwear, traction and temperature resistance on every tyre.

My first yeti on dunlops did 24k on the front tyres. and they had to be changed again before car went back at 65k

2nd Yeti Greenline was on Pirrellis from memory. The car went back at 45k miles with the fronts still legal and perhaps 5k left on them, the rear tyres were still almost unworn.

So how come we need tyre tests? If those data reflected actual behaviours of the tyres the only things that would be different between different makes of tyre for given TTT values on a common chassis would be subjective handling results.

I was just pointing out that there is a treadwear rating on all car tyres.
