Modern repro wire wheels for Model Ts- 2oz
21" wire wheels (26/27 Model T) 3oz to 4oz
19" wheels (Model A etc) 3oz to 4oz
17" wheels (30's cars) 3oz to 4oz
Antique cars with wooden spokes and demountable rims 4oz to 6oz
Antique cars with wooden spokes 4oz
Antique cars with wooden spokes and felloes 5oz+ depending on wheel size. Model T 5oz, larger wheels ie. PreWWI Oldsmobile 6oz or sometimes more.
These weights are based on weight guideline, 1oz of beads per 13lbs of wheel & tire weights, older wheels are more out of balance.
In the 30 1/2 wheels with either vintage wire wheels or wood wheels, anything over about 4oz gives a noticeable thump on starting off that was objectionable.
