what size tires

[timohara]

If there is 11x22.5 tires on the bus now can i put any other size on?Its an old bus with dayton rims.

11r22.5 is the standard commercial truck tire. You could obviously go smaller (10r22.5, 295/75, 275/70, etc.) but the top speed will be reduced. Did you get a line on a cheap set that is a different size?

I have been checking around on new and used tires. I looked today at some that looked pretty good that where on a bus. Somebody was scrapping the bus. They were 275/70. This guy scraps out a lot of buses. I never saw so many engines stacked up waiting to go somewhere.

The 275/70 tires are around 37" tall. The 11r22.5 are around 41" tall. This is a pretty big drop in size and top end. Unless you are doing just city or lots of hill climbing, stick with 11 or 10r's.

We have the opposite problem. Our bus has 255/70x22.5's and I found a nice set of almost new 10r22.5s, but they are too tall.

I put 22.5 lp's on my truck and it rides like a buckboard. Someone here told me that 11r22.5 has more flexiblility in the sidewalls and yield a better ride.

Something to consider.

low profile = low speed but I guess those mini donuts help you get up a hill!

Don't forget to consider wheel width. Every tire's going to have a design-wheel width upon which the performance characteristics are based. Generally speaking you have some latitude between the next size up and/or down wheel, but anything other than tire size that agrees with the design wheel width will deform slightly, altering the contact patch and potentially affecting variables like traction, wear, or mileage.

For reference (see pages 74/75):

If you install tires too wide for the rims it's probably no big deal on the front wheels unless they touch the tie rods at full lock, but it could be A Very Bad Thing on the rear duals: there's a high likelihood they would rub together, and that's a guaranteed red flag to any DOT inspection. The most important thing with tires is to never use a lower-rated tire than the manufacturer's specified size(s) on the vehicle's data plate, and to keep the same or similar RPM (revolutions per mile) rating; if the RPM is different by more than a very few percent the speedometer/odometer will need to be recalibrated.

At a bare minimum, the tire isn't going to wear as designed, the mounted dimensions won't agree with what's published, & the ride quality will suffer. Maybe not 'end of days', but I'd consider those issues significant. Though admittedly far less problematic than rear tires rubbing as you point out.

yes 10r22.5 uses a narrower rim than a 11r22.5. however i seen lots of the low profile series use the 11r22.5 rim

Its 100% ok to put an 11R on a 7.5" wheel as long as the tires don't rub each other in the back.
