Anyone have comments on the Dunlop , toyo, falken, Pirelli, options on a cup car vs Michelin and yokes?

I'm familiar with yokes and Michelin but have not used the others in the last couple of years.

Any recent experience wOuld be helpful.

Pirelly DH = very good & long lasting & consistent

Dunlop = same...Bob Scotto uses these alot IIRC with great results

I use both the Michelin and the Pirelli. The Michelin is faster, buts goes away after 3 heat cycles, maybe 4. They are a lot slower after those cycles and they are done by 8 or 9. The Pirelli are a little slower, but consistent and are good for 7 or 8 cycles with some degradation of performance, but they can be practice tires for more than 16 total cycles.

How do the Pirelli's compare to the Yok's?

Thx!!

Really like the pirelli DH. I don't think it has the magic michelin (or even yoko) laptime in them but they are very consistent and usable for several runs. I set my fastest lap of the weekend at the glen in sprint race 2 after using the tires new in race 1. I ran used pirelli's the entire weekend at Atl and won both races. I think they are a great choice.

Has anyone tried the Pirelli DS or DSS vs the DH? I'm looking for time to come to temp and overall speed vs longevity.

Veloce Raptor

Yes, and also see Cory's comparison above. I concur with him. Yokes are slightly quicker but the Pirellis are a better all-around tire for a weekend, or even a long race, IMO.

Haven't tried the DSS. The DS does come up much more quickly IMO, usually within less than a lap at normal ambients, and is quick but is only good for a couple of cycles before dramatic fall off, and in high ambients even within the session. Again IMHO.

What sizes are recommended for a 996 Cup? I recognize these would push a GTC3 car into GTA1, but having size recommendations for the various tires (Pirelli, Yokohama, Dunlop, Hoosier) would be helpful. Are there meaningful suspension changes that must/should be applied for different tires? (If so, this would negate any potential cost savings of trying/having different tires.)

Just trying to be better informed on the subject.

Yoko size is the 250/650 and 280/680. I made the change to that tire from Hoosier on my 'Baby Cup' which has the same suspension as your Cup.

Camber is one item that changes, where different rubber seems to like different degrees of camber.

The biggest difference may be ride height. If the height of the tires is being changed, so will the rake of the car and these cars seem to be very sensitive to that variable. Michelin and Yoko can be interchanged relatively easily, but Hoosier not so much.

Thanks Rob for the info. Really appreciate it.

Anybody have data for Pirellis or Dunlops?

I have used the Dunlops for years. They have a wider section width than the others even though the listed size is the same. They cost more than the yokes but are a better tire in my opinion.

Whew, I thought Glen was selling Slick 50 now...

Anyone have any experience running Hoosier slicks

good hands

I don't have a lot of experience on Slicks but the Hoosiers require way less camber than Yokes. I corded a set of rears at Sebring with 4 HC. I used Yokes earlier and they wore very well.
It seems that different brand slicks require pretty dramatic different set ups.
