    Good luck. I've been looking for 4 of them for several years now. I have found some farm tractor tires that are that size but the tread pattern is typical tractor.

    The 10.00 x 24's were correct at the time the grader was manufactured, but this size became officially obsolete in the mid-1950's as tire manufacturers standardized on a lesser number of sizes.

    If you acquire some later parts books, and compare the individual wheel hub/rim part numbers and drawings .. you'll find that either the rim pressing or the wheel hubs were modified in design, when Cat changed over to the 13.00 x 24 tire size.

    From late 1955 to mid-1956, Cat changed over to tubeless tires on all motor graders, wheel tractors, scrapers and wagons. The new tubeless tires required a new three-piece rim with an o-ring seal.
    Earlier model graders, wheel tractors, scrapers and wagons could be retro-fitted with the new tubeless tires, but the new tubeless rims were required as part of the deal.

    You will likely find that the newer rims or hubs have a bigger offset to compensate for the wider tires. The changeover to tubeless tires on the 9T series motor grader came in at S/N 9T4762, in Dec 1955.

    Here is a cut & paste from another forum. It's a long shot

    Here's a source for obsolete Cat 212, 10:00 x 24 grader tires. Sent an email to them. Enclosed is a reply.

    Yes, we stock a Denman brand 12 ply. Your cost is $552 each. I can get you freight pricing if you will give me quantity and zip code.

    Default 10.00x24 grader tires

    the thread for McWhorter Tires is dated...02-26-2009, 07:54 AM...
    This is an old message...
    The availability of the Denman 10.00x24 tires had gradually dwindled away by the time I searched for them...
    Specialty Tire bought the Denman 10.00x24 tire molds some time ago...,and thought they might make a run of them...Never could get an answer back on this...
    Do a search for the tires and you will find an old thread of mine about the research I have done on the 10.00x24 tires...
    I have a 212 grader that has 11.2x24 AG tires on the front...They are a heavy tread, but work just fine...
    I had 4 212 rims and locking rings sandblasted, primed, and painted...Then found out the rims were about 1 1/2" to narrow in width to accept the 11.2x24 ag tires...The older rims with riveted locking rings can be treacherous when mounting the tires...
    Right now, I'm looking for the newer 24" rims with 2 separate pieces rings...the newer safer ones...like used on CAT 112 graders...There are 3 separate part numbers for these...I need 4...
    Respy, CarlsCat

    Default Cat 9K wheels conversion from triple ring split rim.

    I didn't know Caterpillar made a 9T motor patrol?? I have a 9K, built in 1939, and have been dickering on an 8T. I remember the 99E series but not the 9T.
    Speaking of the 9K, anyone know what's required to convert the triple piece split rim to a wheel that won't kill you?
    Any help would be appreciated. Thanks in advance Best Regards. H. L. Gleason

    Default Multi piece wheels

    This is not really the section to place this, but there has been some discussion in this thread about multi piece rims, some of which are incorrectly called "split rims". Every one should really read this: https://www.osha.gov/Publications/wh...rt-booklet.pdf it gives in depth information on servicing many kinds of wheels, and even has handy charts for checking the compatibility of obsolete wheel components. Truly words to live by. I would like to add the osha link to the links on this BB. Thanks

    Thanks for that link, STEPHEN. I have copied it into the grader section of the archives. I think it will be helpful to many users.
