    Does anyone here have any idea as to why in the world these 285/75r24.5’s are so dang hard to mount onto rims by hand?? I’ve never, ever had a problem throwing 22’s over a rim and plopping them on, but this is my first time dealing with tires of this size, due to the fact that my truck takes 24’s.

    It’s like the bead on these is so much thicker or something. I usually end up pulling off the old ones at home and take the new ones to my local tire shop to have mounted, but I’d like to keep doing everything at home.

    If anyone has any tips for doing this by hand with spoons, other than buying a big hydraulic tire machine, please comment. Should I look at other sizes for 24” rims? Would love to hear some experience come through. Thanks!

    We used to change tires with spoons, spatulas etc under the shade tree. Even the old 5 spoke 18 wheeler tires with nuts, bolts and preinstalled rim.

    After they get to a certain size we do well just to roll em to a shop so they can pop the darn things on with the hydraulic machine. Save us the aggravation.

    I have same size on my truck. I do all my own tire work and these are no different then any other tire.

    Lots tire soap for lube.

    Having said that, there is certain Chinese tires with very thick beads and sidewalls. Hercules come too mind, these tires can be a bit of a ##### to mount. Michelins of course always are like a hot knife through butter..

    Turnpike is another brand that can be tough to mount.
    I bought 8 drives cheap a few years back. Those were the hardest tire I’ve seen to get on. We hit them with the cheater,and they would pull back off the bead. Had to shoot them with ether to get them to stay on the bead.

    I don’t do tires, but no tire guy has ever had a problem with my 24.5’s. They swear at my 17.5’s though.

    Tires with a short sidewall are pretty stiff by nature. I would suspect the problem you’re having is due to the bead of the tire hanging up on the shoulder of the bead channel in the rim. There isnt a tire bar long enough to pull it over if the bead doesn’t bottom in the channel.

    LP's are always a little tougher due to the shorter sidewall. Nothing to make note though. Add used 10 year old casings and hard rubber and they will fight you for sure, way more than new rubber. Soap and water to dismount and veggie oil to mount. Running spoons.

    Always a challenge getting cold recaps to seat the beads, especially if they have been stacked flat and the sidewalls are sucked together.
