Thanks Ralph. I really try not to be a stick-in-the-mud but the OE Goodyear’s are what was certified on our car with all the production testing to verify compliance to all the design requirements. Yes, this does include legal issues which I am sure Ford remembers the Firestone Wilderness fiasco and they would not want to get anywhere near that legal quagmire again. Especially on a halo car like the GT. Thus I am sure there are huge safety margins built into the OE Goodyear tire application.
Indy, you are right but I believe many tradeoffs were made to keep the lawyers ok with the 205 rating. True we don't have a lot of instrumented data on the Bridgestones, for example, but the mileage and usage is accumulating quickly. Included are many mile runs and even some road course and 1/4 mile events. I'm increasingly convinced that the Bridgestone will prove out to be a better tire. Just my opinion.
And Kendall, as always I respect your technical opinion very much. In principal, I agree with you. And as time goes on more and more owners will be abandoning the GY’s in favor of the latest “hot setup” no doubt. We will get more data on these other combinations as time goes on. I am sure there were a number of technical tradeoffs necessary to arrive at the OE GY, like wet traction, snow, mud, dry pavement wear, noise level, etc. etc. There are always compromises to be made in a given design. And you will have to admit that even though some of us owners with Brigestones have run “the mile”, ¼ mile events or even some road course events, that time-at-temperature/speed would pale in comparison to the testing I am sure Goodyear had to go through to convince Ford this tire was indeed safe for sustained 205 mph on the GT.
There were a lot of tires tested that were worthy, GY wanted it the most.
Specracer, If I interpret your statement and equate your use of “lot of tires tested” to tire companies wanting to supply FGT tires, I do not believe your statement is accurate. Possibly at the initial request for tire proposal stage there may have been a couple tire manufacturers interested, but when the team actually got into the program, I believe there were no more than three tire companies (if that) who wanted the business (or could deliver a supercar tire). And yes GY did want to be the spec tire on our car. The development team put them thru the ringer to get exactly what they wanted for the tire on our car. Believe me, GY did not just pick a tire off their product line and hand it to Fred’s team and say here-you-go.
