Recommended Wheel and Tire To Replace 4.50-10 Tires On Concrete Mixer

Question:

Looking for 2 replacement tire wheel combo for a concrete mixer 4 on 4 bolt pattern. Factory shipped with a 4.50 x 10 Carlisle tire. I have clearance for a slightly larger wheel tire combo. On a budget what do you think?

We have an option that will work perfectly for you.

I recommend replacing the 4.50-10 tires on wheels that have the 4 on 4" bolt pattern with the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range C # AM30630.

This combination has wheels with the same 4 on 4" bolt pattern, and the tires will be .1" wider and will be right at 1.5" taller overall so you will have no issues based on the clearance you can see in the pictures you provided. Keep in mind that only 3/4" of that will be on the top of the tire so it really will not be that much taller.

The # AM30630 has a 990lb load rating at 90 PSI so it is plenty heavy duty for your concrete mixer.

I included a video of the # AM30630 for you to take a look at.

I used this info for a similar problem with older version of this commercial cement mixer... but the lug pattern is 3.75 (95mm) instead of 4.00 (100mm) so it did not work. I do not see a workaround tire for this application... and the recommended tire is also too large for the wheel well and will rub. I'm not making this mixer roadworthy, but I would like to be able to move it around on wheels. Finding 3.75 rims is very difficult.

@Chuck Does your cement mixer have a standard axle with a removable hub? Or is the hub part of the wheel? If it has a removable hub you may be able to find a new hub that uses the same bearing combination but a more common bolt pattern. If you cannot find a new hub your only option is find a way to add more wheel well clearance (lift kit, or raise the fender if possible depending on your unit). If you're unable to figure it out yourself a local fab shop should be able to help.

I still have the original tires and tubes though the tires are quite dry rotted. I'm trying to figure out if I can get foam into them to inflate them permanently. This will at least allow me to have rolling tires for moving it around. I have to adjust the tires first to line up the tubes correctly before injecting foam. I believe this may be do able for a cheap fix. There are also adaptors available for 4x3.75 to 4x4.0 but at a hefty price and I would have to remove/redo the fenders (not a real problem) if I wished to make it roadworthy. It's an old beast and I just want it for its larger capacity as I have a lot of concrete to make for a new foundation under an existing barn. I bought it quite cheap, so I asked for issues...

@SamuelC It has a torsion axle. I have not looked at it closely enough to see if the hub can be replaced with another (assuming I can find it). I can certainly mod it myself if needed but wish not to. There are still a few options left for me to make it rollable.
