Hi all;
We looked into aircraft tires once about ten years ago. All the
ones in the 26" to 30" dia. range were very heavy, some as many
32 ply. I think Les Leggit tried some back in the 70s.

> As for the tire wear I believe you are right on as to the loading &
unloading of the IRS. I have simulated the rear lift by putting the car on a
lift and moving it up to the height I believe it runs "at speed". If you use
the stock suspension & Strut rods & mounts it will travel over 2 degrees. If
the camber goes over center, the car spins, so this is a critical thing. I
got the car to go straight thru trial & error, tweaking the alignment after
each pass until I was happy with it. Last year at SpeedWeek (98) somebody (I
think it was Bill Ward) said "yeah, maybe it goes straight at 210, but how
do you know it will at 220?" To make a long story short, that comment got me
thinking about handling at future speeds. Didn't get the changes made for
this SpeedWeek, but am doing it now. By using stronger brackets, heavy duty
adjusting cams, and using thicker strut rods, I have the camber change down
to 1/2 degree.
> Much better, but if this car was ever to see some serious speed, I would
have to put in a solid rear end. My goal for now is to put the C/GT record
up a couple of notches and then move on to something else.

in Texas, I believe that sold military surplus tires to farmers as is or
recapped with a traction tread. They are nearly indistuctable and
impervious to nails and thorns. Any how there are jet aircraft tires in
the 28 to 30" O.D size that appeared perfect to me. The price as I
remembered was under $50. I asked a friend of mine that's a aeronautical
engineer, I think he can spell it, He said well they are made to sustain
very high loads for a short period of time, I also learned that the
military sometimes recaps these tires several times, so I guess they don't
break down very much. I forgot to mention that the tires are 12 to 20 ply
and for 15" or 16" wheels. I guess we can assume that its okay to run
these tires as they have and are being run on the salt since that's what
the big diesel trucks run and that F- series!

real tall ones on the back for the gearing advantage. I am sure these
tires are big bucks new, but it may well be possible to get some good used
ones for a small percentage of the new cost. I wouldn't count on me to be
able to find the address of the company that sells them but I'll look
around maybe someone that is adept at Internet searches can find it or other
sources. L. Kvach Butters,,,, oh ya I am wandering if the strange wear
pattern on your tires is from your IRS loading and unloading Ed, or not
being evenly heat cycled when they were first run????
