While we're fking all the quotes up, what ABS thread would that be?

Don't know what all the fuss is about.

The ABS on my car frightens the crap out of me and on ice when all four wheels lock it doesn't work anyway, I wish I could turn it off.

You need to read the ABS thread.

I said nothing about ABS...thanks.

Ot was Jagracer who came out with the ABS comment. Something went wrong with my quoting.

....and the RE70's are a Summer tyre, in cold weather that nice sticky rubber goes hard and brittle, you may as well be driving around on some shiny plastic discs!

They are an all year tyre, just like your run of the mill tyre is, they wont work as well in the cold as they do in the warmer temperatures, just like all other all year tyres. The issue with them compared to more run of the mill designs in snow is simply down to a large block design that isn't going to clear the snow as well as a more open block design of tread pattern. The rubber compound is actually on the soft side, which is why they can generate grip and heat even with the larger block pattern, in cold temps the tyre has similar grip to any other normal tyre until the grooves are filled.

The compound may be soft in normal temperatures, but what happens to it in freezing temperatures? Soft compound trrack-biased tyres tend to become hard tyres in cold temperatures. Winter tyres have special compounds that remain soft in cold temperatures. But you must know all this.

du uh, just like all the other all year tyres as i said, the RE070 isn't a track tyre, it's a performance road tyre. Read the winter tyre thread and you might see what experience I've had of those tyres too.

Hence my "But you must know all this". It's not just track tyre compounds that harden in cold temperatures. All non-winter tyres suffer from this to an extent.

I know, I've said the same multiple times including in the quoted sections above, so why you keep stating something as though it hasn't already been stated is bizarre.

Traction A - Means they are really st in the wet, think ditchfinder tastic
Treadwear 120 - means a soft compound that possibly seriously hardens when cold
No Rain Sipes - st when wet
Large blocks that can't flex when cold - like driving on plastic


Probably the most dangerous type of tyre in sub zero conditions, I would like to think that PH type drivers knew a little more about the tyres they were driving on.



Info on ratings here
http://www.etyres.co.uk/tyres-ratings-nhtsa/tyre-t...

Traction A doesn't mean ditchfinder in the wet, that would be a traction B or C tyre, even looking at your link it says 75% of tyres out there are Traction A rated, only 3% are traction AA.
Treadwear 120 means just that, the wear rate is relatively high, the chemical makeup of the tyre will determine how it reacts in the cold, your statement is pure speculation. If you are interested in temperature range, you should look for the rating for that, which is A, the same as the vast majority of tyres on UK roads.
No Rain sipes, it has a very open pattern in the areas of the tyre not designed for cornering support, they clear standing water well, like any tyre as they wear the wet performance suffers. All tyres lose water clearing capacity as they wear, the 1.6mm mark is far too late to have decent clearance on any tyre, 4mm is what tyre engineers will tell you is the required minimum depth for good drainage. You can have these tyres steaming in the wet, they can give huge grip.
Large blocks does not mean plastic tyres when the compound is soft, of course if you want a winter spec tyre then the block size is much smaller for the reason you state, but you also have a compound that is designed to work with a block that moves around more.

If you want to talk about this tyres weakness, it's ability to clear snow is compromised because of the treat pattern and width, but that doesn't mean it's worse than other tyres in the other areas of performance.

What you've said here is very true. These tyres do still function surprisingly well even in snow. As long as the snow isn't deeper than the grooves they are no worse than any other non winter specific tyre I've ever driven on.

Thanks for the link but that's 22 pages of a few posters arguing amongst themselves. There is only one post that's of any use and that's jonathankk's insight into how it' supposed to work.

Thinking of you, OP...

Yes this is well worth a bump, one of the classic all time PH threads.

Hilarious thread, not only was there snow but apparantly a layer of oil strategically placed ontop of the snow for added lubrication.

[KaraK]

I was thinking just yesterday about who would be the first to have a "Syndrome" moment during this current snow

[petrolsniffer]

This thread should be bumped every winter

[zakelwe]

If only he had fitted winter tyres as well, alas it was not to be.

Andy

[mattman]

ahh - this thread should be locked down as comedy genius.

Karma in action perhaps?

Lesson to self - if you're going to be smug on PH about other peoples failings - don't be a numpty and post a rant about your own!

[robsco]

Nice bump, and a lesson to us all.

I was thinking about this morning as i was drifting round a very nice corner on the way to work.

[Stubby Pete]

Thanks for the bump, missed this one last year. Just have to say what a great sport the OP was, started off thinking he was a big headed dick wh got his comeuppance but tirned out he was just one of "us" who made a slight error and accepted it as a lesson learned. Hat off.

[anonymous-user]

Nice bump.

This made me chuckle after this years fun

I ran these tyres at this years scooby shootout, which was run in horendously wet conditions. Result was winning the standard car class by 3.4S and finishing 2nd overall, 0.3S off the outright win, behind a full race spec Time Attack car on BTCC wets, beating all the other Pro and Modified class cars.



Don't work in the wet my arse.
