Has anyone taken a bus with 12-22.5s and gone down to 11-22.5?
I am considering doing this and would like to know if anyone has and if so what, if any, noticeable or adverse affects.
The 11-22.5 is much more common and a way lower cost.
Our axle weights are 12500-20000-9000 respectively way within the limits of the 11-22.5 tire. I have spoken in detail with my tire guy and the diameter difference is so slight he does not think it will noticeably affect the spedo.
I own my own tractor trailer and it has the 11-22.5 tire and could eliminate the age issue by taking them off the bus before they get too old and running them there. |

Make sure your rims are not to wide.
Most buses I look at have the 11's . |

You are correct to specify the 8in rim for the 11and12-22.5
The aluminum rims are easy to identify. The style holes in the 8in. rims have bigger holes and more of them than that of the 9in rims. To me the 9in alum. rim looks odd because of those smaller holes. The 9in rims accept the 310 and 315s that are the next larger tire from the 12-22.5.
Some of the newer slide conversions are approaching 54000 and are 20000 on the front and being equipped with super-singles on the steers. It's gettin crazy with the gross weights. We weigh in at at 41500 and in my opinion that is PLENTY heavy enough! |

Two things you need to be aware about when you start changing tire sizes.
First, make sure the weight of the coach does not overload the tire.
Second, be aware of how many RPM's the tires will turn in a mile. Some 11X22.5's are actually taller than some 12X22.5's.
Personally, I don't like the 12's. Not only are they a whole bunch more $$$ and harder to find but the need for greater weight capacity is just not there for most coaches.
If you have a "fleet" already, I would standardize the tire size so that you can use the coach tires up before they die of old age.

I tried the 11R22.5's and they were smaller putting the coach closer to the ground. So I put on 11R24.5's and was much better Jerry |
