I want to start looking for some used Aluminum Wheels for my Eagle. My 72 has 24.5 wheels. What wheels will fit and should I change to 22.5? I will need tires before I start using the bus. Thanks | ||

I bought mine used from a truck tire place. I had to change all the studs because aluminum wheels are thicker. That was expensive. I don't remember how much. Check a truck supply place for prices. David | ||

Spend $6.00 at the CAT Scale and get it weighed. If you are OK within the weight limits of 22,5 tires great. If its so heavy that you need the 24's , so be it. Your fuel mileage wont change , so is shiney wheels worth a grand or two? FF | ||

I run 12r 22.5 on my Eagle and weigh 41,000 you can buy the longer inside nut for aluminum wheels without changing the studs if you use a steel wheel on the inside as most do. check the front wheel studs if there is a 1 1/2 in of thread showing from the nut on the steel wheel you won't have change the studs on the front | ||

It's perfectly fine to change to 22.5 as long as you keep some things in mind: Your suspension ride height will of course be 1" lower. Check to see if that will cause problems. Also, if you mount a 22.5 steel wheel on the inside drive, it MAY not clear the drum. In other words, you may not be able to completely pull the wheel up tight to the drum face when mounting the wheel. I ran into this when I tried to put new Accuride 22.5 steel wheels on the inside. The problem was that the steel wheel offset is different than the aluminum wheel offset, creating clearance problems. This is not a problem with the larger diameter 24.5's. You CAN use aluminum on the inside as long as, as mentioned,you install longer studs. Best to fit a wheel on the bus first before mounting up the tires and check the clearance. I gross 43,000 lbs. and run 31580R22.5's on 8.25 Alcoa Durabrite wheels and use a standard unpolished aluminum wheel on the inside. Also, the weight capacity of the tire(s) is based on the tread width, not the diameter. You can carry 600 lbs. per inch of tread width. Consult your tire manufacturers spec sheet for proper load ratings, pressures and speed ratings. Hope this helps. | ||

Depending on what you are planning to wrap the 22.5 wheels with, your suspension may or may not change at all. Some of the 22.5 tires overall height is the same as the 24.5 low pros. As stated before, If you check with a reputable tire and rim dealer, They will set you up with what you need as well as what you are trying to achieve!!! -- BILL | ||

Keep in mind if you change to 2 inch shorter wheels, your top speed is going to be a couple mph less; your engine is going to cruise at a little more rpm than before and consume a little more fuel. Of course this is going to depend on your overall drive ratio. If it is something like 3:70 to 4:11 you may not like it. If it is 3:08 to 3:50, it probably will be a little benefit. You will gain slightly in hill climbing ability. Of course, this is going to depend on overall tire revolutions per mile in the change. After using the larger ones, the new ones will look a little like casters in comparison.Yes, I'm exaggerating a little on the casters. Find the tire/ speed/ final drive ratio chart that is online somewhere. Somebody here should be able to point it out for you. | ||

on a 12rx22.5 the revolutions are from 492 to 485 depending on the brand of tire a 11rx24.5 the revolution is 480 and 11rx24.5 and the 12rx22.5 are about the same in height as Bill stated.Mallie Lennon has a web site that has a calculator for the speeds of different tire sizes if someone has an address for it.I will keep looking for it have a good day www.cwis.net/~mallie/ (Message edited by luvrbus on June 16, 2008) | ||

Where's the revs for 12:00x 24.5? | ||

you tell me John I have never saw a 1200x24.5 except for off road use.I am sure if they were available the log haulers would use that size instead of the 1200r x 22.5 | ||

Every tire is different. Get the revs per mile specifications from the tire manufacturer for the tires you are considering. 22.5 and 24.5 are only rim diameters, it's the tires you put on the rims that are the final determiner. All those old standards about size and revs are just that: OLD, and out of date. lots of combinations that will change your tire diameter/final drive without a forced rim change. See your local tire professional for details. happy coaching! buswarrior |
