A few months ago there was talk on the list about bush tires on Kitfoxes. 

   

  Please find attached a picture of my KF3 with Nankang tires. I've rolled the plane up to 45MPH (well above normal operating speed) and they roll just fine and landings are a little more forgiving.

Charlie,

 Could you provide some specifics? Size, price, source?

 Thanks,

Hi Greg:

   

  I ordered the tires from Tiresunlimited.com

   

  The tire size is 21 x 12 - 8. The model number is N800 and the part number is T30151002, they cost $27.64 each plus shipping. They'll arrive tied together and it's a little tricky getting the tires mounted since they are collapsed and don't seal against the rim. I tied a tourniquet around the periphery of the tire and this forced the inner tire to mont on the rim and hold the 5 PSI the tires need to roll your Kitfox.

   

  So far I have about 60 landings on the tires and they have been a joy. Expect a very mild jolt when you touch down on asphalt, since there is a lot of tire that has to get spinning, but landing on grass or gravel is is always a charm. On a tail dragger, your prop will have about two extra inches of clerance. I cannot say how much cruise speed has been effected by the new tires, but what ever  it is, it's minor. The tires wiegh the same as the original tires the kit came with.

Jeff:

   

  Max gross for the Grove landing gear on the Kitfox3 is 1,200 Lbs. 

   

  The tires are rated to only 355 lbs at 5 PSI, so I keep my gross weight to no more then 710 Lbs.

Charlie,



I think you might be underestimating the Nankang tires.  I flew with them on 

my Model IV for about three years and never hesitated to fly at 1200 lbs. 

This flying included lots of off pavement landings.  I suspect the tires are 

rated as they are because they are designed for the ATV market where rough 

terrain at fairly high speeds is common.  After my chrash landing, which 

tore the aluminum spring gear off the airplane, one of the Nankang tires was 

still inflated and the other was flat.  I didn't have time to carefully 

examine the flattened tire to determine why it lost air.



I am not suggesting abusing any of the equipment we use, but in this case, I 

think in the normal use of these tires on our airplanes, they are fine up to 

the rated weight of the airframe in the earlier models.



Yes, these were the tires sold as Kingfox.



Lowell

They look just like the kingfox tires I put on this year.  I load them right up to 1200 gross on the plane.  I took mine to the motorcycle guys and let them install along with balancing them.  I run them up to 60mph at times for some exciting wheel landings and wheelies(run on one wheel).  No problems with shake.  I've put about 5000 touch and goes on these things this year alone, they still look great.  I wanted to try them out in the snow on the grass runway, but the airport closed it and wouldn't let me land on it.  They sure know how to make a grown man cry sometimes don't they.  I had to settle for a runway that was with packed snow and ice, did a bunch of wheel landings with stop and goes.  That was fun.

Sorry if it is obvious....,   The tire size is 21 x 12 - 8.  Does that mean the tire is 21"high, 12" wide?



Thanks,

Merry Christmas,

Mike:

   

  Have you any Alaska-style water/sand bar landings? Water sking on the fat tires?

Charlie,



I have seen lots of waterskiing with the group we fly with.  No water to 

sandbar landings yet.



Go to: http://highwingllc.com/videoarchivepages/smoothwater.html  for a 

look.  I have tons more video of the guys doing that, but am behind on my 

video editing due to the hard landing on Aug 30th.



This guy had regular aircraft tires.  I suspect the wider tires would float 

a bit better.
