Tires.....

[luvrbus]

295x80x22.5 is more tire than you will ever need ,you have 60 series with the world Allison 6 speed with 2 overdrives no way it will affect the performance the speedometer has DIP switches to adjust for accuracy,You are not buying tires for a older equipped 2 stroke engine and 4 speed transmission,my Rv has 315's on the steers because of weight and 295's on the tag a drives with a GVW of 58,000 lbs from the factory,I bought all new Toyo's made in Japan.FWIW Ironman is a dam good Tire made in China the tour operators and school buses use those here in 100+ heat in Az

You will seldom if ever have the waste and the fresh water tanks full at the same time. It's usually going to be one or the other, or somewhere in between.

What are the thoughts on run of the mill tires for the rear and top tier for the front?

12:00R x 22.5 is the max diameter fairly available for your current rims. The others will cost lower cruising and top speed. I don't  know what tire companies were thinking, making the 305's smaller in diameter than the 12:00's they were to replace.

Hmmm, now that info makes may lean strongly toward 22.5s

Thanks

That's logical.

All tires are not created equal, you MUST review the spec sheet and confirm the revolutions per mile for each tire being considered, tire size alone is not an indicator of what they will do to top speed or your speedometer.

B500 has a tall .64 overdrive, so the 4.56 is a decent compromise between power and economy, in the buses of that vintage. And they will FLY, if given the reins...

Good condition tires all the way around... ever seen how a blown tire can tear up the guts of a coach? Any savings will be a total eclipse of the wallet...

Happy coaching!

Hello Bus Warrior,

As always you bring sobriety to any thread.  With the knowledge you have, reading these sheets is probably second nature.  I on the other hand am a newby, so I quickly get information overload.

I will do the best I can and run things by you guys for input.

Thanks  a million.

Here's the carnage on a eagle from what I assume was a blowout.

Yeah, food for thought.

That is what I have been doing.  I keep the best tires on the steer axle.  Roadmaster by Cooper tires on the drive axle and BF Goodrich tires on the steer and tag.  I move the steer tires to tag axle about every five years or so.  It really depends on how fast the tag tires are wearing.  I never really wear out tires, but rather they age out.

The BF Goodrich tires now on the tag axle are made in Brazil and the BF Goodrich tires on the steer axle are made in the USA.  The steer tires are less than a year old and I was surprised they are made in the USA.  I just bought a new set of Roadmaster tires for the drive axle.  I ordered them in January and it took two months to get them.  I think I missed out on some of the price increases.  I really wanted more of the BF Goodrich tires, but not available and much higher cost.  I decided I had good luck with my current Roadmaster tires made in China so I decided to go with them again.

Tire dealers that have contracts with school districts may possibly allow you to piggyback off one of their contracts if you want 12R22.5s.  That's what I did when I bought six Yokohama 104ZR tires (made in Japan) two years ago for about $3000 out the door, and they ride better and tramline less than my previous Michelin XZEs (sorry, Tom!).
