As original, the fronts a tad narrower, the rears a tad wider than a Formula Ford, assuming that the mandated FF wheel width is the same as it is here. The tyres have changed more!


The tyres on a Kent engine Formula Ford are all limited to 5.5 inches.

The tyres on a Lotus 27 Formula Junior were 4.5 inches at front and 5.5 inches at rear.

On both cases they were on 13 inch wheels.

Something like Dunlop R6 tyres back in the day?

Yes, R6s...

There must be photos around showing the tyre sizes used, but I'm sure I remember seeing 5.50s on the front and 6.50s on the rear.

Ray that could have been on the 1.5 litre cars, as I was quoting Formula Junior sizes, the only regs I could find.

Wasn't Formula Junior was finished in Australia before these cars arrived...

Interesting that there was a second chassis for Arnold.

The tyres on Scott's car at Symmons in 67 (in the shrubbery) are demonstrably wider than those on Arnold's car in the OP
