I recall some time , some where, I found a tyre chart for 350 x 19 tyres , which gave the true rolling diameter of various makes including the original tread depth. I've looked in all my files etc, but am unable to re-find it . Has anyone seen or got a copy they could post on the forum please.

Hi Peter, I think you will find that information, albeit formatted in terms of revs per mile, in appendix 2 of Bill Williams "Austin 7 Specials" book. Also, if you visit the Longstone Tyres website they list nominal diameter but not rolling diameter for all makes and sizes that they stock.

I measured a Cheng Shin and Longstone 3.50x19 today.
Cheng Shin 6ft 11in circumference
The Longstone was 1/4 inch more,both off the car.
The deflection on the Longstone with weight of the car is negligble compared to Cheng Shin.
