Who is this, what is the car, and what is going on which is of particular interest?

Tyre testing?

YES! But it's a very specific tyre test.

Radial testing?

Radial testing?

Nothing like that. Look closely.

I will have to think. The tyres look balloon like and either slicks or bald.

They are indeed treadless. For a reason.

To increase or decrease adhesion?

To decrease it, I suppose. It would be to lessen rolling resistance.

Fuel economy run?

ok , i know i saw this pic while doing research for another salt flats record setting puzzle but i can't remember the details , this is a Dunlop Design or testing Engineer i am not sure when they where testing the coefficient of friction on the Salt flats .

Sorry Richard, nothing to do with fuel economy. Foxawy has reached the correct conclusion. This is a Dunlop engineer testing tyres for a speed record attempt.

I will now LOCK this for foxawy. Please answer the questions I asked for the point - there is something which is very important about these tyres and what they were going to be used for. I will lock it for 24 hours.

Ok here is what i found , so the car in the picture is a Elfin ‘Mallala’ Ford used for surface testing !! these wheels were a smaller scale replica for a land speed record car .

YES! What was the name of the land speed record car?

foxawy · « **Reply #19 on:** September 17, 2015, 03:08:27 AM »

Bluebird ?

Bluebird ?

Correct!. Thank you for trying so hard - most of my puzzles get ignored!

The man in the car is Ted Townsend, a Dunlop engineer, and he is using an Elfin Mallala single-seat race car which was fitted with 13-inch exact replicas of the wheels which they intended to use on Bluebird for the Land Speed Record attempt. This was at Lake Eyre in Australia, a dry salt lake just like Bonneville. The wheels used on Bluebird were much larger, but this test gave an indication of whether the design would be suitable for high speeds.

A well-deserved point.

This photo shows the size of the actual wheels and tyres on Bluebird.
