New guy here with some questions

[Desertdueler]

I am getting ready to convert my "new" bus into a RV/toy hauler. It is a 1990 international school bus. It was a 66 passenger bus. I have no idea what engine is in it, or trans. Can anyone help me. I do know it is a 3800 model international. It has a navistar engine in it, big inline 6, and it has a turbo and intercooler. The transmission is a 4 speed. Next question is it has 9r20 tires on it, 10 lug. Are they split rims, because they look like one piece? They are tube type, and I don't see a why to split the rims. I am also thinking of putting some 11r22.5s on it, do you think they will fit, or at least in the back? Right now it cruises right at about 65-68, and trying to get a little more, and or bring the rpms down a little. Any help is greatly appreciated. BTW is $250 a good deal for 6 22.5 rims with decent tread 11/22.5 Goodyear 5159s?

Grab those 22.5s NOW!

As for the tranny, take a look at the pictures I posted under Everything Else,
How to tell Allisons apart. Most likely you have one of those two.

And welcome aboard!

Went and got the 22.5s. They have goodyear G159s on them. 4 have some tread above where they are regroovable, and the other two(look like front by the way they are worn) are to the regroove marks. I will probably buy two new fronts and find someone, or try myself to regroove them. Thanks for the info on the trans, I will have to get under there and look.

Well, now it doesn't sound quite like "decent tread" anymore , but since new tubeless
rims cost $100 each, you are doing OK. DO get good steer tires. :!:

Yea, I was kinda bummed about the tires not being in as good of shape as desribed, but I drove almost 400 miles round trip, so I figures, I an only into them about 300 bucks, cheaper than the cost of rims. I may just put the 22.5s in the back for now, and keep the 9r20 up front since they are almost brand new. I will just carry a spare for both since I have both now.
