Everybody's got a favorite "pet" track tire.
Personally, I prefer not to run Dunlop's U.K. made front line slicks, rains, intermediates, and racing DOT tires. They lack a circumferential belt, causing a couple of concerns that I choose not to deal with. They grow at speed. Pretty significantly. To the point of rubbing holes in front fenders and putting shiny spots on the crotch of the swingarm. From time to time you'll see (and smell) a Dunlop rider actually smoking as they approach a high-speed braking zone. I have read about more catastrophic high-speed Dunlop tire failures than all other brands combined. You don't have to be a rocket scientist to figure out that putting them on a really heavy, really powerful bike is going to put you at a higher risk than anyone else. They also don't transfer heat from one side of the tire to the other. So for example if your track is mostly right turns (like PIR) with only one left of any significance, you can get the right side of the tire hot in one lap, and then suddenly take up high-speed gardening on lap 2 in a left turn. They are also notoriously unstable. They are just not happy going in a straight line, and they just don't seem to ever really settle down. It's distracting. These comments do not extend to Dunlop's second-tier U.S. made DOT track day and street tires. Dunlop's contingency program typically pays the best.
I also prefer not to run Michelins. My reasons are personal and have nothing to do with the performance of the tires. I just prefer not to buy French products. There have been a number of reports of Michelins letting go suddenly without warning. The president of our racing association lost a very nice Blackbird using Pilot Powers on a track day, and I haven't seen him go down in the six years that I've known him.
I chose not to use Pirelli tires because the tire vendor at PIR has an ongoing intimate relationship with himself and his mother. But I like the tires, so I run Metzelers. They are the same company, and you can pretty much buy the exact same tire in either brand, with just minor cosmetic differences between tread patterns. 17" Pirelli/Metzeler sporting tires have a circumferential belt that transfers heat from one side of the tire to the other. I can mount a brand new set of tires, do one sighter lap, and I'm ready to rip on both sides of the tire- without warmers. They don't grow at major speed. If you can see daylight between the tire and a hard part in your pits, it's not gonna touch. They are extremely stable. To the point that some Pirelli/Metzeler riders remove their steering dampers. Watch an Isle of Man video and try to find any rider that doesn't use Pirelli/Metzeler tires. Pirelli/Metzeler's contingency program typically pays the worst, but tire contingency money is nothing compared to motorcycle manufacturer contingency money, so I say run whatever you think will put you on the box.
