Radial tyres may need to be run at slightly different settings. Many of our members say they use 30 lb./sq. in. front, 35 lb./sq. in. rear, and this appears to work effectively and safely.
The original configuration used inner tubes within the tyres. The wheels were therefore not necessarily designed or manufactured to be airtight. Many members run with inner tubes, accepting that there is the possibility of abrasion between the inner tube and the wheel. There is an interesting article on this subject in The Globe August 2021.
