yre and wheel tech

[whodaky]

On getting my new purchase home I pulled the wheels off the race car and commenced to get the rim out of the tyre. to my surprize I found the tyres had an inner and outer.

The 3 pieces that make up the wheel and tyre. It should be noted that the front tyres are smaller in diameter and width than the rears! In this article I will be only dealing with the inner part of this wheel tyre assembly, that is the piece in the background of this image!

The front and rear tyres as viewed from the back before pulling them apart. The piece in the middle will eventually be trimmed out.

A front in the foreground and a rear in the background that has had the centre trimmed out and the white lettering sanded off

This image shows the 2 different size tyre sections that I will be using in the rest of this artilce.

I thought what to do now. I then got out a bunch of 1/8th tyres and thought, why not try a side wall from some of these. Well as it turned out for the small diameter casing, a front tyre half (they are 2 piece) from the Lindeberg T bucket fitted just nice and for the bigger diameter casing I just so happened to have a rear tyre that I had cut in half from the black issue big Deuce that was just the right diameter.
The Lindberg half tyre was a tight fit and did require a bit of sanding to fit in nicely with out the slick area of the main casing flaring out slightly. The Big Duece half tyre was a real nice fit into the big diameter casing. Note I left the tread section on the donor side walls as this allows them to located nicely!

This one is a winner. It leads the way to making wider tires that we'd normally have to completely scratchbuild which we all know ain't easy.

So how do they look

Big diameter one which is 3 3/4 ( 95 mm ) in diameter and 2" ( 50mm ) across the slick area

The smaller diameter one which is 3 5/8" ( 90mm ) in diameter and 1 7/8' ( 47mm ) across the slick area.
Using this technique these tyres could be easily narrowed. Or the same technique could be used using say a piece of PVC pipe ( instead of the casing from the F1 race car ) and using donor side walls on the inside and outside of the tyres!
The opening for a rim on the donor casing is around 2 1/4" ( 57mm ) which is larger than those in the 2 donor side walls. That is, what would now be the inner side wall of these 'new' tyres

Like I said, BINGO!! That's outstanding. Great tip.

Now for some inspirational mock up shots of how these tyres look. Firstly the big diameter.

More inspirational shots. The smaller diameter tyres

coupe shots, because I was having fun playing mockup!

Something else I noticed in my travels for the elusive model part is yoyos.


And for this exercise when the yoyo is disassembled rims came be made for the backs of the slicks in this article. These yoyos are cheap and come in a variety of styles.

Those coupes will be chopped when i eventually do something with them!

OUTSTANDING Geoff! You are teaching us the difference between looking and seeing. Perhaps you could be persuaded to give a tutorial on how to chop a top. Flathead V-60 aka John
