Looking for real world experience from users that switched from A7/R7 to Pirelli's. Lap times, speeds, fall off rates, etc.etc. Guessing it won't be apples to apples if you went from new to scrubs but still curious. I am currently considering trying scrub Pirelli DH from new A7's. Thanks

I switched from A7 and R7 to Pirelli scrubs. Scrubs stick as good if not better and last longer. I've never done an actual comparison on a single day where I removed a good Hoosier and put the PZeros on to compare, I just tried them, liked them and quit buying the Hoosiers all together. Texas summer heat will get to them with hard running after 20 minutes or so, but I can back off and they'll cool back down. Best tire I've ever run, honestly.

Saying all of that... if I had to pay retail for them, I would probably be buying the Hoosiers again.

Continentals are terrible.

My experience has been the same. Don't use Hoosiers any more, just Pirelli scrubs. Cheaper and faster, don't fall off during a run. I usually get 12-15 good heat cycles out of a set.

what exactly are "pirelli scrubs"?

Mordeth

They are used, significantly discounted take-offs from racers. Usually have 2-4 heat cycles. Still alot of usable life left but a racer is done with them as they have started to fall off. They are referred to as "scrubs". Good for DE guys that don't mind giving up a few tenths or so, aren't actually racing and want to save money.

thanks for all the replies. My issue is size, my car is set up to run the hoosier A or R7's in size 315/30/18 and 345/35/18 and the Pirelli's come in 315/680/18 and 325/705/18.

What kind of car? For the C7 widebody cars I recommend the 305/660-18 and 315/680-18 combo. The diameters are pretty much exactly the same as the stock sizes. Yes, the rear might seem narrow but they work well. Given that my 680s will just kiss the rear wheel well liner at stock ride height and I can't imaging a 705 working.

I have a lot of race scrubs, Pirelli and Hoosier, for sale in southern California, but I don't want to ship them. Local pickup only. I have more coming as I still have the SCCA Runoffs in Sonoma and the last Trans Am race at COTA in the next five weeks.

thanks, but what kind of tires are you talking about? slicks? because somebody mentioned p Zeros.

Mordeth

Any kind of tire, but typically reserved for used racing tires. I'm not sure why P Zero was mentioned. The term "scrubs" does not refer to a specific tire manufacturer but rather that it is a used tire taken off a race car that still has usable life. The "magic" is usually gone, but is still a good tire with usable tread and a number of heat cycles left. Could be a Pirelli slick scrub, a Hoosier R7 or A7 scrub, a Continental slick scrub, a Michelin slick scrub etc etc.

Poorsha uses them and now I see Koan does as well. Both Driver's that are ridiculously quick in their cars.

I tried them on Poorsha's recommendation and liked them better than the Hoosier A7's ESPECIALLY after the Hoosiers get some laps on them. The Pirelli's I thought were significantly better over the course of a weekend than a Hoosier. I will use up the Hoosier's I have and won't ever go back unless they are free.

Pirelli DHs work pretty good up to about 70 miles into a 100 mile Trans Am race. It is around miles 60-70 that I notice them beginning to give up some grip. But even at that point in the race I have been able to set my fast laps as I burn down my fuel load.

I still love my Hoosier A7s though. It is fast instantly and it is an incredibly resilient tire through a 40 minute race and with a number of heat cycles. It is a great tire IMO.
