WATCH THIS VIDEO BEFORE BUYING TIRES FOR YOUR GRAVELY WALK BEHIND TRACTOR

These gravely tractors don't have that much ground clearance to start with so smaller tires make the machine closer to the ground and more likely to get hung up on stumps and holes etc. Also, with the smaller tires the handle bars are a lot closer to the ground which make operating it more uncomfortable. Learn from my mistake, buy the larger tires.

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..

Thanks for the info

LoL I have a L1 with the tractor tires, one facing forward and the other facing backward to get traction in either direction...

[@phillipgriffin3901]

Just bought a project L Needs new tires and tubes. What is a good source?

Ebay or Amazon.

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.

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.

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

What were the bigger tires? I want as big as I can get.

[@jameschang8122]

you left out 1 number how tall are they 16 inchs or taller

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.
