The Dunlop 4.95x3.5 (6 ply) is no longer available. This tyre was used on many Slingsby gliders. Some Nippers are flying using a military tailwheel tyre of the same size but being 8 ply it is much heavier. Unfortunately I do not know of a source for these either.
One solution is to contact Toste (Germany) and purchase 400x4 wheels and ask for them to be fitted with 6005RS bearings which will fit on your friends axles, and with a little modification the brakes can also be made to fit. They will need to know the width of your existing wheel. Toste also supply the tyres and tubes for these wheels which are rated for glider and aircraft use.
I propose to go this route when I finally run out of original tyres myself.
What is the registration of your friends Nipper?

Hi Patrick,

Has your tire problem been solved?

Would it be possible to send me some photographs of the Nipper with it's new ultralight registration?

Hi Patrick,
I have a question regarding your spats.
Have you noticed an improvement in speed? If so by how much please?
Where did you get the spats from, or do you have a mold?
A little help goes a long way.
