"Squirming" over the road does indeed sound like a grip problem and sounds exactly like the problem of the coating on the tyres, which will take a few hunded miles to dissipate

I wouldn't try and evaluate any tyre until you've properly bedded them in which is immediately what caught my attention of your post saying you took them off with full tread. I'd have left them on longer to bed in and see what happened.

 

Sounds like you haven't come across this requirement ?

Its more common place in motorcycling, guys don't don't respect the running in of tyres on 2 wheels with far too much throttle end up in the gutter outside the place they had them fitted Not supposed to be of amusement to the shops that fit them, but I'm sure its hard to stiffle.

 

Car drivers have less BHP and less attention needed (e.g. keeping up/stable) so I guess its deemed less important, but the problem is still there.

"Your new tyres should be ready to give you maximum grip and performance after 150 to 200 miles.

The tyres will have abraded and the slippery silicone agent used to release the tyres in the moulding process will have worn off."

 

Never mind, expensive lesson in how tyres are produced I guess

When I say full tread, I mean no serious signs of wear, maybe they were down to 7mm, they were taken off with over 700 miles on them and were driven quite hard. A grip problem to me means loosing grip, for instance, in corners or under heavy braking , none of this was evident. They were not loosing traction or screeching. I am "fully" aware that new tyres need scrubbing in before they are up to full performance, having surprisingly purchaced quite a few sets, I am not still wet behind the ears and have a number of previous years motorcycling experience.  Riding with New and old tyres and not experiencing this on anything previously or since. Tyres regardles of being scrubbed in or not should not follow every single rut and squirm all over the road with no apparent improvement and should not feel like driving on beach balls. I replaced them with Eagle NCT 5's and they were immediately better with 0 miles on them and totally unscrubbed with full silicone mould release agent and all..

So, not full tread then lol.
