: Early Impressions of the PS2...

Well, it's been almost 2 weeks with the Michelin Pilot Sport 2 tires on the V. I've got 245/45 18 on the front and 275/40 18 on widened 9.25" stockers on the rear.

What I didn't do was feel the stiffness of the sidewall while they were unmounted. But they do have great feel on the car. They aren't as stiff as the F1s but they are very well connected. The dry traction feels about the same. The wet traction is very good. Not quite as good as the Dunlop SP Sport Maxx but still excellent for a Max Performance tire. The best part is that they track better than any tire I've ever had on the V. The V tracks as tight and true now as any car I can remember. There is one section of Rte 2 westbound, just west of I-495 in MA. It has incredibly bad ruts that would fling the V pretty violently with the F1s and were downright scary in slicks. You don't feel a thing with the PS2s.

Back to dry handling. The PS2s are most amazing for their turn-in and transitional stability. Turn-in is a little heavy but once you get into the steering, the feel in the wheel and tire is incredibly consistent. You get a great feel of what the tire is doing at all times. The problem with the F1, IMO, is that the stiff sidewall gives you strong dry handling but when it breaks free, it's going to do so quickly and somewhat uncontrollably. The PS2 gives you great feel and is easy to read when you get to the limit of, and past, adhesion.

The F1 Supercar and GS-D3 run very wide. The PS2 actually runs the same width, but has rounded shoulder blocks. I'm not a tire engineer but I can see where you don't need to have the absolute max width at the tread to achieve the best handling. Michelin has advanced tire experience in F1 where a tire has a lot of sidewall and aren't allowed to be a straight slick. I think their sidewall design is prevalent in the PS2. It feels that good.

There are some tires that in some tests, have put out better dry grip numbers than the PS2. I've run the V on Hoosier slicks that would outrun the PS2 on a road course. But, part of the equation is which tire is going to be the easiest to get good times on. The PS2 seems to be a tire that most could run fast on because of it's grip and because it communicates so well.

I am now a PS2 rumpswab.

I still can't believe you didn't try the Falkin 452's for a 100 bucks less a tire.

I still can't believe you didn't try the Falkin 452's for a 100 bucks less a tire.I'm sorry. It took me quite a bit of praise from quite a few members here and then on the magazine circuit to have enough trust in the RT615. I didn't believe that a tire could be that cheap and that good. While I believe there can be quite a bit of markup in manufacturing tires, I still believe you get what you pay for. I think if Michelin could sell the PS2 for a good profit margin and sell it for $50 less per tire, they would.

That being said, what I'm starting to hear is reaffirming my belief in you get what you pay for. A good portion of tire $$ is spent on tread compounds and development. While the RT615 is one of the stickiest tires anywhere in street form, the compound is very heat sensitive. If you tool around on the street, that may not matter too much. But in many tests I've seen, the RT615 loses consistency pretty quickly as the tire and track heats up. Tires such as the Yokohama Advan Neova AD07 and Bridgestone RE-01R put up closer times and get better as the heat is turned up. Grassroots Motorsports magazine's lates issue had a nice comparo of those tires.

Going back to you get what you pay for, I decided to get the Michelins because of their almost universal praise as being the best street tire on the planet. While the Falkens very well may give you a slightly higher g rating, all the great things the PS2 can do is the reason I spent the money. The direction stability, turn-in, sidewall consistency, max grip, wet grip and great road manners make this a must buy tire. Period.

I don't have many power mods yet. With every car I've ever owned, it's get the handling down and then the power. You may be slower in a striaght line, but I do real racing. Handling rules.

my ps2s are at about 22k miles now, and alas the fronts are at the wear bars. despite that, they grip just as well as new...although i dont push the car lest i torpedo another fence ;)
their wet performance is confidence inspiring. after 18 months of drought here, its rained for the past 4 months. i used to garage my car in the wet...but since the rains i've realized you just can't hydroplane with these. 60 on a wet highway is no problem. i guess soon i'll be buying more :)

PS2's are great. I ran road Atlanta last week and was doing 140 in some parts, I also was running with a 2003 Z06 that was putting down 422 to the wheels. I matched him turn for turn running full tilt and out ran him on the back straight, after about 1 lap these tires became very soft and sticky. My g-meter now reads 1.19 to the left!!! I will be at the Cartersville, GA car show on the 23rd if anybody wants to call me out. Tires do a great job on and off the track. BTW i run 255/35/19front and 295/30/19 on rear

Didn't get the latest Grassroots Motorsports. That magazine is great. Can't wait to read that article. I have to buy a 2 sets of tires real soon. I am going to put 452's on the optional GM's for the street and try the PS2's for the track on the originals. I am a Falken fan because of the value but I'll try PS2's for the better track times. Thanks for the write-up.
Really, I checked the dictionary, no rumpswab.

As English is my first language, I had already dissembled the word and drawn my own conclusion. "rump" - yeah, we get that. "swab" - ok, a couple of possibilities. Since it was you, naturally I chose the most clinical. :highfive:

Buttsmoocher. I'll file that one along with asshat, a personal fav. :lol:

If you're going to get dedicated track tires get Michelin Pilot Sport Cups, I think Calicadi has these. Don't get me wrong, PS2's ae great tires if you need a street and track tire. I have them on the V and on the Corvette. My track tires for the Corvette are Kuhmo V710's. Great track tire for the price and they are DOT legal.
