I replaced my rears today with Pilot Sports I bought from my friend - it was a great price with 7/32nds remaining. Anyways, I noticed today that when making a U-turn the tires squeeled. Weird. So I wanted to see if I could peel out with these tires. And sure enough, I can. Why is this a problem?

Because now I'm concerned about the traction of these tires. I bought them thinking that they were a great tire with fantastic wet traction. The OEM RE40s gripped immediately, and I've never once been able to peel them from a stop.

I thought maybe all the residue from the duct-tape just needs to be burned off, or something. And after all, these tires haven't been used in months. So I did some more 2-second spins (nothing that induced smoke or smell), and nothing changed.

The tires are well rated on TireRack...but somehow I feel like something isn't right. Is it because they're different compounds? They are both summer tires though...

 

wow if you think OEM re40s are good then you haven't tried that many tires...also that must means the pilots that you bought are really bad >.<

 

I don't think the OEMs were good. They were terrible and scary in the rain. I just don't understand the subpar performance of this tire.

 

I think there are pilot sports tires and pilot sports 2 tires.

Now the PS2 is the bomb~ I don't know about the pilot sports.. Is your's PS2? I absolutely loved my PS2 with APS single turbo pushing about 380WHP.

 

I've been running some PS2's for over a year now and have to agree that they are awesome. I've run them on the track and in a few autocrosses when it rained and found them to be very grippy. As previous poster pointed out, maybe you have the old PS, not the PS2.

 

I know I have the original Pilot Sports. But they're still rated fairly high on TireRack.

 

the thread count, and the wall thickness on the PS2's is different than your pilot sports, therefore making a stronger tire.

 

I know the PS2s are a better tire.

My concern is if these tires have weaker dry traction under WOT from a stop, does that mean they'll have worse wet performance? My tire guy told me that both types of traction don't necessarily go hand-in-hand, and assures me that the wet traction on the Michelins is much better than the RE40, regardless if they peel easier from the line.

 

how about put some miles on them first....your tires are new, and new compounds take some mileage to break in

 

Mechilen's are awesome i have the Pilot sport 2 they are awesome bridgestons are fine for the first 3000 to 7000 miles but after that they start to lose there grip dramatically and when its hot i swear they suck its like driving on butter i say this because in my country in summer temps goes to 120 in shade, think what is it like on black tarmac now i don't say Michelin's performance doesn't decrease but its predictable, and here we have many round abouts and i love street racing and the outer-inner-outer technique, Michelin gives me confidence doing it, there isn't that crucial difference in its performance regarding high temperature. about squealing yes it does squeal not in u-turns i never went fast on a u-turn but attacking turns at high speed it does,,,

my experience with michelin's, dunlop's and bridgestone's comes from SUV'S i know that tires designed for SUV'S are different but any consumer tire design focus on trying to achieve the best traction in every weather scenario with a reasonable good durability, driving SUV'S for 12 yrs i concluded Michelin LTX-MS is the best tire for me than the Dunlop Grand Trek and the Bridgestone Desert Dueler 689 or the 840, it holds its traction, balance and tread thickness for a long time i change Michelin's every 40,000 to 45,000 miles but the 2 others every 25,000 to 30,000 miles but the price has significant difference 620$ for hole set of Michelin's, 400$ for Bridgestone's and 380$ for Dunlop's

Mind you that doesn't mean Michelin is the best tire company but each company has god tires and bad tires.

 

PS2 are great, sticky on the track, quiet on the street, but expensive...

 

Z1: Read the original post. The tires are slightly used, they just haven't been driven on in 6 months.

qxz: The U-turn I did wasn't fast or sharp, at all. I did it pretty slow, actually. The squealing doesn't occur with the U-turns anymore, and neither does it happen in any kind of turns. Another thing was that my tire guy changed the air-pressure, set it to 33. When I first bought the car, the tires were filled 40, for whatever reason.

 

Thats nice to hear,,, i hope they satisfy you by time, its just that when i read about your problem i felt bad for you,,

 

Tire squeal (tone and pitch) is engineered into a tire design. The simple fact that the re040 don't make a sound when spinning from a stop doesn't mean they had more traction. I guarantee you you did make them spin on a take off. You just didn't notice it because they were quiet...

The re040 don't even compare to the Michelins you now have. Rest assured, you made the correct choice. Pay attention on the tone and how it changes with rising (iiiiiiii) and then falling (uuuuuuu) grip levels.

 

Whether or not the tires make noise also depends a lot on the road surface... My re040s are silent on some surfaces and loud on others... I would NOT at all say they are silent... I make them talk to me all the time.

 

Thanks a lot, guys.

Kinda hoping it rains now, hehe.

 

May have figured out the reason why the rears can break so easy under straightline acceleration - they're 7lbs lighter than the OEM Trashstones. That's a pretty staggering difference.
