245/40 R19 Tires

The wet and dry grip has been exceptional with low road noise and moderate harshness. Handling precision and responsiveness have been good, not exceptional. The tires have held inflation pressure very well with minimal leakage. This is my second set and unless Michelin comes out with a better max performance summer tire, I'll buy them again.

These tires were factory fitted on my Volvo V60 T8. They do the job seemingly well and have caused no issues other than inducing some understeer through roundabouts if pushed hard. While the car itself does not seem to encourage this, I wonder whether the somewhat disconnected feel of the tires is more to blame than the car's geometry and handling. I expect to get through the winter and am likely to try something somewhat revolutionary in Volvo circles and fit Continental Sport Contact 7s next year. This will test the theory if nothing else. I think the Primacy 4 is a good tire by most standards and will suit most people, but think it is now getting long in the tooth and can be comprehensively outperformed by more modern designs.

Tires are amazing in dry weather, I got them on VW Arteon 2.0 TSI 280 4x4, and they never break traction, even when pushed. In the wet they are great too although I haven't pushed them in the rain. Tires are quiet but seem hard? Every vibration from the road is much more present in the cabin than it was with my previous set. Front tires are a bit worn after 10k miles but nothing terrible. Rears look almost brand new.

Bought after reading reviews, seemed like a good bang for a buck and not disappointed.
They seem narrow for a 245, which probably affects rolling resistance and aquaplaning properties positively. Pretty low cabin noise. I haven't been driving on the edge, but even with more spirited driving, I couldn't get them to slip. I'm mostly just cruising on country roads and I can not exceed their potential. On wet motorway they perform well and aquaplaning resistance is good. Wear seems OK. Steering feedback is fairly good, but the car being a 5 series with AWD, I expect some numbness from the car as well. Tread depth when new isn't much with 7.1 mm, I am yet to measure how I did this summer as I just switched back to winter tires.

For what this tire was designed to do, it absolutely sucked balls. Had these on my 640i Gran Coupe since brand new (runflats mind you), they are some of the worst tires I’ve ever experienced. Even with “just” 320hp matched with 275/35 R19 tires at the back, it would constantly wheelspin even in 3rd and even 4th in dry weather. Sidewall feels overly firm, makes the ride feel very uncomfortable (runflat could be to blame), cornering felt like driving on wooden tires as the tires told you everything except how much grip you have left, then snap at you almost instantly when you breathe on the throttle. Then we get to the wet, where under 1/3 throttle the traction control would already start spazzing out.

Swapped to Michelin PS5s after these (a supposedly high performance car) and they helped turn this car into an amazing GT car that rides very well. Even under full throttle in sport+ the car would not wheelspin and slide (even in the wet at times). Fuel economy was also just as good as well at 7.9L/100km at best under 70% highway and 30% urban driving. Best part? Road noise is almost 80% gone and ride is so soft I thought the dampers were failing at first.

In conclusion: AVOID Primacy HP unless absolutely necessary.

Excellent dry grip, wet too,when are warm enough.Little Noisy.

This tire was such a joy to drive. No complaints other then dry braking. Very predictable at the limit and playfull, easy to control oversteer in snow. Unfortunately I have cut sidewall on one of them and switched to Pirelli Sf3 which was much better in dry braking, but in winter conditions it had snap oversteer and wasn't so nice to drive.

I'm comparing them to previously used goodyear vector 4seasons gen-3, which were overall fabulous tires, apart of dry braking. Pirellis were definitely better at dry braking, but in winter conditions I was lacking confidence driving on them comparing to GY. SF3 had tendency to snap ovesteer, while GY was lovely to drive and control with playfull oversteer tendency. Additionally in my size Pirelli had none rim protection while GY had large lip.
