Thanks Mark and Melka. Def all good advice. I'm going to try a set of power cups. I think ill go with the 190/55 B. I plan on doing light practice Saturday and racing 4 classes on Sunday. Gtu, mwss, hwss, and hwsb. Should I expect a brand new set of B rated tires to last for that? Will the A's last for that?
so much of what you are wondering depends on your pace/laptimes, and how your suspension setup looks after the tire (but mostly about your pace/lap times). If you plan to only do a few sessions on Saturday (and not run every lap of ever sesson, it's possible ? You can run these tires till the rain sipes are gone, but the lap time does go off like any race rubber after the "new" is gone from a new race tire. I run a tire for 2-3 races, but i wanna run up front with the faster experts every race. If i didn't mind going a second a lap slower in the 3rd-4th race as much, i would just run the one rear a bunch of races. Most AM racers (and even many experts) should have zero problem going near the best lap times they can do, for 4 full races on 1 rear/1 front.
When i was an AM racer, and did quite well as an AM, i ran one set of new tires Sunday morning for our 1 morning practice session and all my races. I also did 4 races, same ones you are doin. Then i used those tires for my practice sessions on the saturday of the next race weekend, then new for Sunday again..
As mark pointed out, the C (although i too have yet to run it) could be a better choice for that many laps (practice on saturday AND racing on sunday), but the B would be better than the A i would think. If you planned on a take-off for practice, then a new tire for the races .. then use THAT tire for your next saturday practice day, that would be a better plan in my opinion.
but my opinion is to run a new set on Saturday to get the feel for these tires and not worry about how many laps you run, then put another new rear tire on for Sunday so you can go a bit faster.. and then run those tires in practice for your NEXT race weekend. This first time on them you just don't have that "last race takeoff" to run for the saturday practice.
i MAY have another take off A 190/55 rear but i know it's on a rim, so likely would not be available for you till mid morning on saturday.
also, all things equal, i would raise our forks through the clamps 5mm as the front michelin is taller than the dunlop. The rear dunlops are very very close to the same size as the michelin 190/55.
I don't know where your getting your tires, but our new michelin FL region vendor will be there at Homestead with everything you need.
