I am not talking about oversteer or understeer, but about tyres skidding after losing grip with the road.

In my opinion and experience, if you slide out at the rear you need to be very skilled at recovering; if you over-correct the car will then spin the other way as happened to me when I was a young man. It's best to learn this skill on a large slippery surface where one can safely spin out.
If you slide out at the front, you simply lift your foot off the throttle and you will regain control.
All of my comments are based on information propagated by the safety authorities.

Surely both understeer and oversteer occur because the tyres have lost grip with the road. They occur when you go just a little too fast for the tyres on the vehicle(that has certain handling characteristics) that you are driving to maintain 100% grip so that you may only have say 95% grip. If you increase your speed you can then end up with say only 10% grip whereupon the front or rear of the vehicle is very noticeably sliding laterally.

I would put the new tyres on the rear.
You can detect understeer and loss of traction in the front and react much quicker to correct than you ever will with oversteer coming from the rear.
How do you know that.? My garage might want to know about these seminars because they put the new tyres on the front too. Personally I think you're making it up as you go.

One new one on left front, one new one on right rear. God how hard is it.

Buy 4 new tyres.

Completely wrong. Both new tires should be put on the right hand side because that's the side that does all the work.

An long-time mate who used to run a tyre shop told me years ago that new tyres should go on the back. (For the very reasons shown in the videos)
So I took heed of his advise from that day on.

Yep put the new tyres on the back.

Damn right, and shout the poor long suffering thing a shock test/replacement and full wheel align by a specialist alignment shop at the same time, proper grip and control are not achieved without these no matter what's on the front or back. Call me an old grouch but I get sick of this Only Do What You Have To For A Wof minimalist mentality, its not maintaining a vehicle properly at all. As for banging on and on about oversteer and understeer, the average weetbix box obtained licenced driver wouldn't know or care about the difference, they might understand that understeer means that you will see what you will hit in front of you and the airbags might deploy, oversteer you will hit what you can see through the back window and they might not. The message really is look after your tyres and not let a significant wear differential set in to start with and renew as sets of four, do this and you might be on PAR for success, that's Pressure, Alignment and Rotation OK?

I would put the new tyres on the back wheels. The back wheels tyres will not wear anywhere near as fast as the front ones.
Now that also means then front tyres will wear out quickly, probably over the summer. Then you will put a brand new set of tyres on the front wheels with a near new set on the rear. That's the best situation for winter driving.
And as your front tyres are new and wear the most, these will be the tyres you replace next time. Which will be ages away.
In the meantime, enjoy your new tyres, safely.

No, its the left side thatt does all the work. Roads slope down to the left, more weight on the left tyres. Go round a roundabout, lots of wear on the left hand tyres.

new tyres to the rear.

i should have read the thread
the videos posted should be watched by all.

OK Google doesn't support my theory of new on the front so it looks as tho the WOF guy and I know SFA.

It would have totally put the argument to bed if they'd shown the videos with front and rear wheel drive cars.
My assumption from the videos is that you'll start to feel the loss of traction with the worn tyres on the front and adjust your speed. If the new tyres are on the front, you'll probably think that all is well and the rear will just let go with less chance of correction. Is that it in a nutshell?
It is only really 100% valid in the wet though. In the dry, then theoretically, there may be more grip from a worn semi slick than a new soggy well treaded tyre - just as long as the rear isn't running on old hardened rubber!
Therefore, it seems to come down very much in favour of the new tyres on the rear, regardless.

Good idea. Saves all arguments and worry.

about right.
this is not new theres write ups around somewhere. its been well tested by several companies/agencies.
with worn tires on the front, sure you have less handling, braking and steering. but you can feel that and drive to it. typically speed is lower. even if you do go to fast the car won't spin out of the control as the rears still have traction and keep it straight.
with worn tires on the rear, the good front tires gives you good traction, handling, steering and braking. which lets you drive faster on the corners. which means you can easily go to fast for the rear tires and go into uncontrollable oversteer.
in testing most people will correct understeer far better than oversteer. understeer you will feel it more easily and natural reaction of taking foot off the throttle induces a forward weight shift which helps increase front traction.
so new tires on the back is a lot safer.

That's pretty much what I got told at tyre shop when I asked. He gave me a printout that explained it all. But basically above, too much grip on front can be a bad thing relative to the rear that is.
