Paging all Goodyear Billboard tire users/experts...

[RedBarchetta]

I believe many of us would agree that the big lettered ("Billboard") Goodyear bias ply racing tires absolutely look the best on our little cars (and in the right conditions, perform the best for a 15" diameter rim). I've been performing some research on these donuts, mostly looking at pictures here on CC and studying the size chart that can be found at Roger Kraus Racing.

Given the fact that not all Cobra bodies are alike (FIA vs 427, or FFR vs Contemporary vs SPF vs ERA vs Kirkham vs CSX, etc.), I understand that one particular tire will take on a better 'stance' than the same tire on a different car. That is where your pics would help a lot!

So purely from both an asthetics and performance standpoint:

1. What sizes are you using?
(i.e. 600-700-800 G7s vs. 'standard' 26.5x8/26.5x10 vs 27x11)
2. Which 'version' offers the best street vs track performance?
(again, G7s vs 'standard')

Thank you in advance for posting pics (or referencing your gallery) and imparting your knowledge onto my content depleted cerebrum.

Here's my car. I am running the standard Cobra size tires. I removed the "EAGLE" from the side.

A few notes...

-The sidewalls were dry "cracked" from new. I wasn't too keen on that, but they told me that's normal.

-The tires were so out of round and out of balance that after adding over 10 ounces of weight on each wheel, I just pulled all the weights off and ran them unbalanced.

-They definitely grip like a track tire. You will be constantly making steering corrections as they grab everything in the road. But after driving Cobras with regular tires, I actually prefer the way the Goodyears grab, you feel more connected to the road.

-Because of the thin race tire sidewall, they leak air when sitting. I have to fill them up weekly.

-Even with the above issues, I've got over 3500 miles on my tires and they have been great. I have gone on out of state drives with my car and it drives fine with no problems.

Hope this helps.

Like Sal, I'm using the standard Cobra size. They do wander all over the road like a Kennedy crossing the Chappaquiddick, especially when cold. But, on the track they are just fine. And yes, they do lose air, though mine don't seem to go as quickly as Sal's. I have not had the ballance problem that Sal describes, but I have heard that if they sit, they will go out of round. Mine have never sat since I've owned the car. 3800 miles so far, and no problems.

Since I like the "look" so much, and do track my car, I'm willing to put up with the wandering on the street.

Ran a set for about a year until I shredded the left rear. I love the look, but they do flat spot - which takes a few miles to warm out and they follow rain grooves on the freeway so badly, I pulled off the first time to see if the T-nut had come loose. Fantastic track tire. When I toasted the rear tire, Goodyear was on strike & there were no tires to be had - so I bought a set of Blue Streaks which I'm currently running until I can procure another set of the billboards. Whatever inconveniences I experienced were more than compensated for with the look.
