Poor tyre wet handling

[dtr]

I am starting to wonder if it is just my "rubbish" tyres causing instability on wet surface. I just had 2x new Mitchelin Primacy 3 installed on the front on my diesel Passat and they are dangerous in the rain. They replaced worn Pilot sport 3. I thought those were shockingly bad in the wet, but Primacy takes it to a new level of unpredictable steering and wheel slip. Rear end had Avon ZV5 and feels better behaved (i.e. it doesn't slide about sideways).

I know I'm used to running all season tyres on previous car and it had epic level of stability whatever the weather. Only sheer ice caused me some scare, but snow or rain didn't make a difference.

Is it more like Mitchelin summer tyres are unsuitable for Scotland, or shall I be concerned about some mechanical issues with the Passat?

Do front to back swap, then you'll have a clue.

When you say just fitted, have these tyres done less than 400ish miles?

Release agent on tyres..................


Is the alignment correct?

The tyres will have a releasing agent on them so they not stick to the mold. If you drive them hard in the wet from the get go you are not going to be happy with them. If you bed them in for the first couple of hundred miles they will last longer and grip better.

Brand new tyres + wet weather on a previously warm dry surface = slippery.....

I suspect they will feel better in a few hundred miles. I had a similar thing with my Goodyear Efficient Grip Performance tyres when they were new.

I would have your car checked out properly on a 4 wheel machine, the Primacy 3 is a great tyre, one of the most expensive touring tyres and have fantastic wet weather performance. I'd seriously look at your suspension etc.
