The BillBoards and or Blue streak Sport Car Specials (G7's) leak a very minor amount of air because the casings do not have butyl liners in them as do tubless tires. They are somewhat difficult to patch if it becomes necessary to deal with a pucture. I have detailed this in the past and will not elaborate here but I have found a way to do it sucessfully that works quite well. Dealing with a flat tire away from home is my greatest concern, it's not something that can be done at roadside from my experience.

Good old fashioned plug kit gets ya home.
Ernie...I had some old (I mean old) P7s on my Butler that were cracking. One day they just broke...no other way to describe it. |
I put a plug in one of mine a couple of years ago, come to think of it, maybe thats what's leaking now? I think it's the same tire... :D
I hear you Jamo, I'm driving real careful these days on 'em. Get the car to the boat and then the transport carrier and I'm good to go! |
Ernie,
How long do they last before they start cracking (time wise). Terry |

Not sure if any tire stores still remember how to patch a tire or not.:confused::D |

Thanks Jamo!! |

The set I had on my Kirkham (that I bought new with the Kirkham), did the same thing. |
I bought mine from a guy several years ago. He had bought them several years before that and had them in his garage while he was building his Cobra, which he never finished. So it's hard to say how old the tires are.

So Erni, You thinking about living in a trailer?
Bill Boards look great and they are good on the track however I am still considering drag radials or Avons. |

These are not good tires to patch in fact most store in my area refused to patch them. They consider them on time use. Have you looked at the inside of a bill board. Mostly thread material and the patch does not stick very well. First hand experience. |
I'm gonna live in the garage and rent out the trailor! :LOL:
Nice place, but the trailer is a bit problematic... |

I had a patch put inside my motorcycle rear tire but had a hard time finding someone that knew how to do it. Most tire shops these days simply want to sell new tires and 'claim' insurance and liability issues if they patch or plug. I think that's BS myself, they just got so spoiled the youngn's never learned from the old guys.

Sal...you must be using bad air. :p
Ernie...I only use a plug to replace not having a spare...just to get me home if that sealant crap won't plug it...then I have an inside patch put in. Morg...Greg at Wheel King will get the guys will do it right...they remember how to grind it nice beforehand. Don't be cheap...tip em. Had them patch one on a previous set that lasted 3,000+ miles. Says alot that only they (and no Goodyear stores in the area) are specified by the local distributor to mount the run flats on the Vette...sometimes takes a 100lbs to get the bead seated...bang! |
Thats solid advice Jamo, I would advise anyone to follow up a plug with a permanent patch on the inside. I'm comfortable with a long term plug depending on the location, size of the hole and angle of the dangle. Not to mention technique, what kind of plug, how you install it, etc. There is a special plug that is actually 'permanent' made for motorcycle tires!
Now speaking of 'Tire Sealant' or 'Spare tire in a can' type of stuff, I've heard it said it will damage an alloy rim. I've also heard many tire repair shops won't work on the tire if you used it. Granted, it's nasty stuff and I hate working on a tire/rim job that has it. Again, I'm thinking BS on this one. I just don't see how 'sealent' could damage an alloy rim? |
It will screw up valve stems and plays hell with pressure senders in modern cars.
With the low pressures we run in the Billboards, I can't see it as much of a problem when they have to break the bead...I don't leave it in there long enough (just to get home). Assolutely a no-no with run-flats (course, you don't need it to limp home), as Goodyear and Chevy make plain in their literature. |
Oh yes, it WILL screw up the valve stems, I forgot about that. It can make it hell to get an accurate pressure reading after using it. Whew, with a pressure sensor on board that would be a nightmare.
Here's a pic of 'mushroom' style plug, I can't say I like them all that much, some brands are better than others. I prefer a brand that ALSO uses the vulcanizing cement, some are held in place by air pressure only. Air pressure only types tend to leak, temporary repair only in that sense. http://patchboy.com/Merchant2/graphi...001/12-210.jpg |

What pressure to you run in your tires. I did a search and what I found was 26 in the fronts and 24 in the rears. Is that in the ballpark? |
On a tight course, I like to run 2-3 lbs more up front, and 26/24 is what I use, for quicker turn in. On an open course or on the highway, 24 all around. Just my preference for how I drive the beast.
