Hello Grigg,
Thank you for the reply. I sent a similar post on a Military Vehicle Restoration forum and they informed me that 34 x 7 was replaced in 1951 by the markings of 7.00-20. Apparently that size is now very uncommon. I was advised to attempt to find the more common 7.50-20 tyres instead. Does this make it any easier to track down a supply of tyres in the US of A?
Kind regards
Lionel
