Help identify disc harrow need tires

[joeamos]

i bought an old set of what i think is an oliver disc harrow. the tires are shot and not originals. i inflated them but when i lift the disc for transport its not high enough and drags down the road. i dont want to get too big a tire because from what i read when i lower to disc if the tires are too big it will not dig in correctly. anyone have any idea the tire size and/or can you identify the model and i will try to find a reference or owners manual

thank you
joe

Looks like a John Deere KBA disc to me. We may have some used rims and tires. Would be expensive to ship UPS. How many lugs on the hubs? Ken Sweet

thanks for the response. sorry it took so long to get back to you. work too much i will measure when i get home. cant seem to find anything around here so probably would be willing to ups if it is correct size. joe
