yep 4.00 is width of tire in inchs. roughly... 8 is the ID or rim size. check spec sheet for OD of tire. 23 x 12 x 10 would be 23 inchs tall OD.... 12 inch ID rim and 10 would be width of tire..
You said the ag (farm) tires dont have much traction going in reverse. I have seen some people mount one tire forward and one tire backward just for that reason. To help in traction going in reverse
Remember that changing the diameter changes the effective drive ratio. (Not the mechanical ratio, that is determined by the gear set.) The taller tires have the effect of raising your gear ratio so that the tractor will have a faster ground speed, but less low speed torque. A quick and rough estimate is that if the new tires are 30% taller then it will raise the effective ratio about 30%. (Just an example, YMMV). I guess that since it's been a year, you have a good idea if things have changed enough to be a problem, but I thought I would post this as a reminder to others.
I have found differences in tire OD between manufacturer. I have an 8123, and replaced the rears with the same size as original. Lost 2-3" in OD. Went back to the market, found same marked size, but in a much larger tire. You really need to know the OD, not usually listed. Keep that old girl running.
I've been researching the size of inner tubes, L-616-TU, for my 1962 Gravely LI and they're shown as 16 inch or 13 inch. It appears that 16 inch is the correct size.

LoL I have a L1 with the tractor tires, one facing forward and the other facing backward to get traction in either direction...
Just bought a project L Needs new tires and tubes. What is a good source?
Ebay or Amazon.
What were the bigger tires? I want as big as I can get.
Thanks for the info
you left out 1 number how tall are they 16 inchs or taller
