4104 tires

[luvrbus]

Watch the wheels they have a inset and outset dimension also,aluminum is the best way to go they are cast and uniform where steel wheels are a 2 piece welded together,I would stay away from the 24.5 the 22.5's are the standard wheel now

What is your rear axle ratio? 4:11 or 3:55? 69 or 79 top speed approx due to gov setting.

Hey Nel, I've got a MC-7 combo, 10 tires total, I'm in the same boat as you, 10 years + on the existing tires.  I'm going with 12R in the front and 11R's for all the rears.

I'm still not buying yet, you will be ahead of me.

I'm with Cliff on this. 24.5" rims are hard to come by. Took me three months to get my entire bus set up with a complete set of 24.5"s alcoas. Inner duals too. I love the larger look but I don't love how rare they seem to be. I'll be buying a couple more as spares and keeping them in my enclosed trailer at my in laws for future needs if I ever crack one.

11R-24.5 is the tubless version of the tube type tire, 10.00-22. 11R-24.5 is mostly only used in North America. Practically all the rest of the world uses 22.5. Course, 22.5's are available from 8" wide to 14" wide, or 235 to 455 in metric. Big variance of tire sizes. Make sure you have the proper wheel rim for the tire size. Good Luck, TomC

Not all 10 lug wheels are the same,, look for HUB PILOTED or STUD PILOTED wheels to see the very important difference.  There also made in different width's and weight ratings.>>>Dan

Just a guess here, hub piloted would be the rears and stud piloted would be the front's?  You know the stud pattern speak?

Nope stud pilot front and rear axle on older buses

Thanks for the suggestions everyone, I do not know my rear ratio but would like to keep it near original; My 4103 has 11/20's and front measures 41.5" diameter and rear 40.75" Fronts are Generals rears are Michelin 11.00r20 x with tubes.  Thinking tubeless is the way to go.
Now if I could only find a site that lists 22.5 tires by diameter.

EDIT: Anyone run a single tire in back like the Brigestone X one?

or the Ecopia single?

4 tires when you could have 2?! seems like less of a pain in the butt.

If you live in the upper right sweet deal on these Ecopias on Ebay..

Looks like duals it is, thx TomC!

Anyone have a photo of a 11r 24.5 setup?

It's in the background of the picture I sent you a couple months ago of the steel 24.5" rim.

George -

The stock rear axle ratio on a 4103 GMC is the same as the stock ratio on a 4104, in other words, 4.125:1.

Thus the following is important for you to consider when purchasing new socks and shoes for your coach:

GMC designed your powertrain (OEM) around tires that turned 495 revs per mile.

If you purchase tires that turn MORE than 495/mile, your top speed will suffer, your fuel mileage will go down slightly but your startability on slight grades will improve.

If you purchase tire that turn LESS than 495/mile, you will experience the opposite effect.

All commercial tire dealers will have the revs/mile info in their specifications book for the brands they carry.  Use it to your advantage, based on your operating criteria, when you select new shoes for your ride.

By paying attention to the above information, you'll give your coach an OEM ride and performance.

FWIW & HTH. . .

Bottom line to change tire size, read TheMightyQuinn post Boom.

The 24.5 rims that are stud centered are the hardest to find, there are more of the hub centered available. A lot of the stud centered ones were scrapped because they are apparently more prone to cracking. Switching to hub centered would mean changing the axle style, so that is not practical. Part of the cracking problem is the over-torquing of the wheel nuts, they should not be set as hard as on steel wheels. Alcoa has good details on their website.
