understeer is not your definition. it is the progressive loss of front grip while going around a bend too fast, which leads to the nose falling slowly out of the circle. Understeer is not a term used for what happens when the front loses grip suddenly in response to water, or a man hole cover etc.
understeer means the slip angle on the front is greater than that at the rear. Anything else you add about progressiveness or suddenness is in your imagination.

Fair enough. Lets use understeer for front wheel aquaplaning then as it will hopefully stop the derailment to jargon and get us back on track .

For understeer caused by aquaplaning on the motorway you would prefer to have your least effective tyre on the front of the car?

Just so we know where you are in the actual thread.

Yes.

Though in reality I drive to the conditions so I have never aquaplaned in nearly 3/4 million miles.

I just got round to putting 2 New Cross Climates on the rear but the tyre guy was adamant that new tyres always go on the front in fwd cars and he has always done this. We disagreed and I explained why per this thread and also showed him Michelin’s own website which states that if you’re changing only two tyres put the new ones on the rear, regardless of rwd or fwd.

At any rate he still said it ‘made no sense’ but agreed to do as I wished without complaint. Well, he had a good laugh with his mate about it.

Anyway part worn rears are now on the front with half a chance of wearing out before they degrade too much with age. 5 years old in March 24 so I’ll keep an eye on them.

There's a few videos like this that just show you the answer:
https://www.youtube.com/watch?v=hLBrNdz7K00

That's a good one with modern FWD & ESP operational; For a more dramatic watch there is one with an old Lincoln Continental somewhere biggrin

You probably won't die a horrible death; ESP will sort you out (mostly) - It is worth rotating tyres as you'll get the full life out of both "pairs" and can replace as full sets for perfect consistency.

I'll do a rotation alongside seasonal swaps, Or when there's ~1 - 2mm difference front to rear, aiming to "balance" the wear as much as possible whilst I'm expecting dry weather, when the tread depth will have little impact on me falling off the road.

Yep vids say it all - glad I stuck to my guns.
