I think I would have to mail it to someone with the knowledge of how to share it easily. Any volunteers? ________________________________ Message 2 _____________________________________ Time: 04:48:30 PM PST US From: Larry Cottrell Subject: Kolb-List: Baby's got some new shoes I finally got my new rims from Matco. They had been on back order for almost a month, at least it seems that way. I had already ordered the 8.50 X 6 tundra tires and tubes. Today dawned cold, 22 degrees but calm for a change. It eventually warmed up to 44 degrees and I went to the hanger to start my tire mounting. I drilled 6 holes in the rims to screw the tires to the rims. The tires fit tight enough that it takes about 20 lbs of air to make them pop out on the rims. That is unlike the Azusa rims that depend on small flanges on the inside of the rims to keep them from spinning. Since I want to run 5 lbs or less I am still not going to take a chance on shearing off the valve stem, thus 6 screws per side. Before I changed from the 8.00 X6 tires, I rolled the plane out and flew all four corners of the compass with a vid camera to monitor my airspeed. The speed averaged out to be about 66 MPH indicated. The same on the ground speed depending on with or against the wind. There was little wind, and my ASI and Ground speed are really close under those conditions. I drilled and cut threads in the rims, and then mounted the tires. Since the 8.00 x 6 tires are on Matco rims as well, I just changed the three bolts that held the bearings in the other tires and changed them to the new tundras. The wind was still holding its breath, so I rolled the plane back out to check the difference. It seems to roll better with the tundra's on it. I taxiied to the other end of the runway, and began my take off. I cannot be sure, but the tires with 5 lbs of air, seemed to bounce a bit on take off, but I could not be sure. When I pulled back on the stick it flew quickly. I tend to push the stick forward to pick up speed, so it could have been trying to fly, while I was pushing it back on the ground. I will be doing a lot more testing when the weather again cooperates. My take off seemed to be quite a bit shorter than normal. In essence there was no indication that my air speed suffered at all. It was quite turbulent so I only made a circuit and half. While I seemed to bounce a bit on take off, I bounced not at all on landing. The tires at 5 lbs are really nice. They appear to not need balancing, unlike the 8.00X6's. Larry -- The older I get, the less tolerant I am of those who are intolerant of others.

If so, how do you keep the screws from puncturing the tubes? Just curious as I am happy with my Black Max brakes, tubeless tires and aluminum wheels on my Firefly. Apples and oranges, I know....

If so, how do you keep the screws from puncturing the tubes? Yes these are tube type tires. The screws don't go all the way through the inside rim of the tire. The screws are 3/4, so I put a washer on them and they are just right for length that way.

During the upgrade connections to the Matronics and AeroElectric web servers may be unavailable. Additionally, Matronics Email List email will not be redistributed. Internet Connectivity bandwidth will be significantly increased by a factor of 7X for downloads and 50X for uploads, which represents a significant increase in performance. Reliability should also increase in terms. I will send out a follow up message when the upgrade has been completed. Best Regards, Matt Dralle Matronics Email List and Forum Admin.
