Pinnacle Racing Posted June 28, 2009 Share Posted June 28, 2009 So the issue is this. I've run the Good Year Eagle G19 R430 Compound for a few years now and they work well on my 914-6 set up with the typical negative 1 degree of camber at all corners. I just bought Hoosier Bias rains, and found out that Hoosier has a contingency for us. I never ran a Hoosier R45 or R35 Bias slick. Dimensions for my ride are the same. My concern is will the Hoosier give me similar performance and feel as the Good Year has. Good Year is also light at 18 lbs. mounted on my 15x8 Fuchs wheels. I would like to take advantage of the contingency Hoosier is offering but not at a sacrifice. Any thoughts would be appreciated... Quote Link to comment Share on other sites More sharing options...
mcmmotorsports Posted June 28, 2009 Share Posted June 28, 2009 I have raced on both Hoosiers and Goodyear's before, just not on a road course. However, I have been told their characteristics are pretty much the same with both variations. With that said, here is what you should expect: Hoosiers: Faster than the Goodyear right out of the box, but won't last as long. Goodyear: Consistant and longer lasting but not as fast as the Hoosier. I know that what I said is pretty much self explanatory but it really depends on what you want out of a tire. My experience with both tires btw were acquired at a little short track just east of you in Riverhead. Quote Link to comment Share on other sites More sharing options...
Pinnacle Racing Posted June 28, 2009 Author Share Posted June 28, 2009 Ok, So can you answer this perhaps. The GY comes in a 250, 430 and 600 compound from soft to harder. The Hoosier comes in a R35A, R45B, and R55A compound. 1- What compounds cross reference each other from GY to H. 2- Hoosier makes an A and a B in their designations. Does anyone know why and what they mean respectively? Thanks in advance... Quote Link to comment Share on other sites More sharing options...
mcmmotorsports Posted June 28, 2009 Share Posted June 28, 2009 Phil might know the answer, I will email him to chime in here. Quote Link to comment Share on other sites More sharing options...
philstireservice Posted June 29, 2009 Share Posted June 29, 2009 A's are older, not age of tire but issuance of compound, B's are the newer compound. The B compound is the newest compound...stickier and longer lasting. I would, and have, run the 45B most of the year. I would run the 35A in the colder early months of the year and the colder later months of the year. Also 35A's make great qualifying only compounds. 250 = R35A 430 = R45B 600 = R55B or A PS I've yet to see any NASA competitors on Goodyear, the reason, no contingency from Goodyear. It stands to reason if you win on Goodyears you have beaten someone on Hoosiers. If you win on Hoosiers then you have beaten someone on Hoosiers and you win tires. The tires are so close that the car/driver will make the difference IMO. More SCCA guys race on Hoosiers and win, then race on Goodyears and win. The past June Sprints one week ago at Road America, almost 2 to 1 were on Hoosiers over Goodyear. Quote Link to comment Share on other sites More sharing options...

The past June Sprints one week ago at Road America, almost 2 to 1 were on Hoosiers over Goodyear. As someone who is switching from the R6 to slicks soon, I have been looking into this same thing - H or GY. No GY contingency makes it obvious for NASA, but for SCCA both H and GY give out 2 tires for a win. It is my understanding that the opposite of what is posted above is true, at least for Prod cars. Don't a lot more of the Prod guys run GY than H? Quote Link to comment Share on other sites More sharing options...
Pinnacle Racing Posted June 29, 2009 Author Share Posted June 29, 2009 Thanks guys and Phil. Our conversation earlier did the trick. Goodbye Good Year... Hello Hoosier... Quote Link to comment Share on other sites More sharing options...

Don't a lot more of the Prod guys run GY than H? In SCCA Prod.....it might be a little more bias toward Goodyear over the past few years. I think the split is probably 50 percent or pretty near close to that. As far as winners in SCCA I think there are more Goodyear winners, in Prod, at the high profile events. But it doesn't pay to run Goodyears in NASA . Quote Link to comment Share on other sites More sharing options...
