Great tires!

8 days ago
I started this winter off with a set of these tires. They are very excellent tires with great traction and were an outstanding deal on sale. They got us in very quickly for their expert installation which was much appreciated. I highly recommend these tires.

Great Tires!

10 days ago
I have a 2022 Mini Cooper 2 Door Hardtop. I did not like the tires the came with the car. The ride was horrible, and I could never get them balanced well. I'm extremely happy with the Michelin Pilot Sport All Season 4 tires. They have improved the ride, handling is better and I can balance the tires. The only complaint is that that my gas milage has dropped just a bit especially on the road.

Yes, I recommend this product.

Only the Best

13 days ago
Have now purchased 4 sets of these tires for 3 BMWs (X1, X5 and a 7 series). I wont purchase any other tire if I can help it. These are the best tires on the planet and I hope they continue to improve. Cant wait for the AS 5's to come out. They offer extreme grip in wet and dry and corner like on rails. I do get some snow in Virginia and these tires are adequate for light snow. I've never lost traction on any surface. Its why my family only runs these tires on all our vehicles.

Yes, I recommend this product.

Awesome experience

Had some cheap brand on my CT200h when I got the car first, drove like that for 6 months, nothing special, and it’s not the sportiest car but I decided to get Pilot Sport AS4 and didn’t regret at all, car started feeling softer, and literally every aspect upgraded to maximum, the performance, handling, cornering are awesome, now every ride is a joy, thank you guys for the quality you provide!

Yes, I recommend this product.

Q: I own a 2022 Tesla 3 Long Range and I had to change the 4 tires from another brand after only 12000 km. Unbelievable. I see that these have a mileage rating of 70000 km. Does this mileage rating apply to EV's?

  • A: No- EVs are much heavier than ICE cars, and you will go through tires faster.
