Michelin Pilot Sport A/S 3 87 vs 91
 

For those considering this wonderful tire and debating on the 87H vs 91W issue:

IMO: the 91W version are worth the bit of extra money, not much difference in impact harshness or road noise and the steering precision and grip are wonderful.
Much better match for the car than the stock rubber.

Yeah, typically you just want to go with the higher speed rated tire.

You should look at the SSP's. I have never seen anyone disappointed with them if cost isn't an issue.

I think the all season aspect is important in making this decision.

I don't think you will ever notice a difference. The biggest difference between those tires is the load rating. Sure, the higher load rating tires have a bit better construction, but you will likely never notice on this car.

To those All-Season tire haters, and there's a lot of them. This new Ultra High Performance All-Season tire by Michelin is considered by many in the industry as the holy grail of tire technology. In countless tests it out performs all other All-season tires, and almost all Max Performance summer tires.

I'm picking up a set in a couple of weeks for my new wheels. This is my DD, not because racecar. It snows where I live, 5 inches yesterday, and the stock Primacy summers are all around terrible. Plus these are 500 AA A rated, so you'll get 2-3 times the tread-life with these, compared to Max Summers.

Btw, these go up to a 103Y. The speed rating varies by tire size.

i had resigned myself to giving up a little bit of performance (also a DD)... was blown away by how good these are. noticeably better than the pilot sport a/s plus which was darn good and a previous fav.

basically this is a pilot super sport that doesnt start to feel greasy as temps drop.

The speed rating is also important. Because a higher speed rating requires higher heat dissipation capability the higher speed rated tires often have stronger but lighter sidewalls than lower speed rated tires. It isn't just load rating that affects tire construction as you will note from the price differences.

Each tire range may be different. Ask a tire professional what the actual differences are before you choose.

I definitely don't think that what you said and what I said are mutually exclusive... Higher speed rating almost always results in a higher load rating due to the better construction. Considering that the OP's car will most likely never see the max speed of the H rating, I don't think either matter much in this case.

I'd love to know your definition of a "tire professional". Because if it a salesperson at your local tire shop then I am a "tire professional".

For a good review on the Michelin Pilot Sport A/S 3...here you go.

"Next up was a dry autocross course and as we rounded the clubhouse I saw the cars: 6-speed Subaru WRX STis. This would be fun. The real twist here was the competition. In what I thought was a pretty ballsy move, Michelin pitted the A/S 3 against its competitor’s Max Performance Summer Y rated tires, not their all-season rubber. These included the Continental ExtremeContact DW, Pirelli P-Zero and Bridgestone Potenza S-04 Pole Position.

The Michelin was the big eye-opener with overall grip and predictability as good or better than the others..."

yep! thats what we got...

No, not at all. I was clarifying your recommendation and supporting it. There is a reason to buy higher speed or higher load rated tires than your car needs but generally it isn't useful.

I only buy my tires from a pro ( in fact he even calls his shop Pro Tire and he is). 30 years in the business and he gets his info continuously and directly from the manufacturers. He also uses his product intensively himself.

Dedicated tire retailers in Canada are experts in the field.

ANY tire is a better match than the stock rubber. I can't believe Michelin makes such a shitty tire.

I drove the entire duration of my break-in with the stock Primacy HP tires and they almost killed me on wet tarmac when cornering a little faster than normal. Once I got the Pilot Sport A/S3 installed I can feel a difference instantly in steering response and grip without even driving fast down the street. These tires have so much grip in the wet they are amazing!
