Re: KRnet> Tires change

Similar to Roger, I have been plagued by the Cheng Shin Lamb 11-400x5 tires going flat for unknown reasons, even with the 8 ply tires. My KR is 650 lbs empty, takeoff solo is about 925 lbs, Max gross is 1150; almost every 6-12 months on the dot, I would get a flat tire with almost no indicatio

Hi Roger, Plans built with the retractable gear? What does yours weigh empty? I have a plans built with retractable gear and the data plate says 540 empty, I am going to weigh it soon to check the CG. I haven't flown it yet, but getting close. Limbach 80 hp. On Fri, Jul 21, 2023, 8:45 PM Roger Bul

Re: KRnet> Tires change

I am running 4.00 x 5 on my Kr. My kr is plans built so it is fairly light by now days standards. When I fly my take off weight is around 800 lbs by myself. My tires are 8 ply and I run them at 50 to 55 PSI. I had a lot for trouble early on when I was running 35 PSI with 6 ply. They would go fla

Re: KRnet> Tires change

Hello Stef, After 2 blowouts on the KR-2S (and wheel pant damage) within a week I changed from the smaller tires to the 500 x 5 tires and haven’t had any problems since. Smaller tires are lighter but if they aren’t rating for the weight and speed you will have a blowout eventually. Combine that

Re: KRnet> Tires change

The reason some aircraft go to 6 or 8 ply tires is due to landing speed and weight. Remember that tire goes from 0 to landing speed instantly. The stress on the sidewalls can cause failure. Are you willing to distroy or damage your aircraft for a few pounds.  Joe.From: "MS" Reply-To: "MS" , "KRnet

Re: KRnet> Tires change

As someone who has gone through a wide variety of KR tires over the years, going to less sturdy tires seems to me a false economy Stef.   MikeKSEE On Friday, July 21, 2023 at 02:51:43 AM PDT, Stef den Boer via KRnet wrote: Hi all, To reduce some weight I am lookig for lightweig

KRnet> Tires change
