How do you tell?......I recently put another rim on my truck in the rear, I matched them up pretty good as far as eyeballing it.....Now my outer right rear is wearing down (Evenly) and the inner stays fine.

Not sure what you mean by eyeballing?  On hub-piloted wheels, the center hole in the wheel should fit reasonably snug to the hub.  The lugs are just holding the wheel on, they do not center it (that would be stud-piloted, like what you see on typical light trucks - half tons, etc. with the conical seat lug nuts.)  If the wheel has any real amount of play around the hub then it'll be the wrong wheel, or a damaged wheel.  If you run one of these I would be in a hurry to remove the wheels and carefully inspect the studs for damage from the wheel flopping on there.

Pretty much any and all 8 and or 10 lug 19.5's will interchange . . .

Did you get your self some good traction tires yet ?

   I have 235/85R-16's on Mad Max,and 9.50R16.5's on the '76-of course these aren't <HD> trucks,either. what are the big differences between the "Plain ol'" one ton and the "3500 HD" one ton? Am I on the wrong Forum?

In a nutshell the "OEM"  3500HD is a 15000lb GVW 2WD dually truck, straight axle up front, 10 lug 19.5" wheels, and has the distinguishable header panel under the grill. The frames are massive as compared to regular 1500, 2500 or 3500 GM trucks, seeing is believing. You'll see member 3500HD trucks with various conversions, ie crew cabs and 4X4 - not originally offered by the factory. If you have a dually..you're in the right place. The forum is a place for the beefy 3500HD and other dually trucks, read the 3500HD history section above and you'll learn more them...any dually requires a specific place for tech info and parts especially with wheels and driveline.

And BTW: I'm no expert..I learn something new here each day!

I have 235/85R-16's on Mad Max,and 9.50R16.5's on the '76...

I'm glad I'm not the only one that "names" my vehicles...   :D

Good luck with the 16.5's...  that size tire is getting harder and harder to find... (I'm in the same boat with my HMMWV wheels, as they are also 16.5")



And to stay on topic...  Currently, I run a Bridgestone steer tire in front (that came to me with fairly good tread), and General(core)/Goodyear(retread) tires on the rear...  all in a 225/70-19.5 variety.

I have an extra 19.5 tire in great condition, but no extra wheel, which doesn't make me feel good...  but that will change... 8)
The front tires will also change when I get off my butt and toss the Dana60 under it.  ;D

   Thanks,Ed;
     By the 15,000 pound reference,you mean what the truck is rated for,not what it typically hauls,right? ;) Just about all of my trucks have been roped into hauling,or towing considerably more than they're rated for,usually short trips (10-300 miles) just to save time or the expense of renting a bigger truck. Besides,with the price of gas,I tend to load up pretty heavy so I won't have to make two trips. So far,about the only adverse effects have been bending the rear corners of the bed downward a little on Max-the mostly '74 one ton.
   Kargo Master;
   Actually,naming the latest truck "Rocky" was the PO's idea-she says that truck doesn't really start to work right until you ask it to do the impossible,then,when it looks hopeless,it digs in and does the job.  ;D And so far the 16.5's are doing okay,outside of one that leaks down around the bead. They are all about 80% still,so I'll go ahead and use em until replacement time,then scout up wheels to change size.
   Hey-will the 19.5's fit the hubs on my mid 70's one tons? What diameter do the wheel/tire assemblies measure out to? I'm just wondering if they'd give me a little taller overall ratio,maybe gain a few mpg's,lose a few rpm's? I'd probably have to either modify the fenders or work up a lift kit of some sort.
   Something to think about.....

Ironic, years ago 8 lug split rim budd 16.5's were the norm, but no one wanted them when the solid budd 16.5 came out. Then the 16" budd wheel became standard and nobody wanted the solid budd 16.5 (I know - I have full set of 16.5's that I can't move).

Now - the 16.5 tire is sought after??? ???

   I actually prefer the 16.5's for towing-the shorter,stiffer sidewalls make 'em a lot more stable than the 16's under a heavy load.

If you like the 16.5's then go get your self a set of 19.5's . . . nice handling, awesome tread wear just a good all around fantastic tire.

You beat me to it Mike...

Also, as far as I know... there's only two load ranges available for the 19.5 tires...  "F" and "G" and at 90 psi...  

If you haul heavy stuff, you'll never go back...


Ed, I don't know about 16.5 tires being sought after...  I was just saying that it's not going to get any easier to find tires for them...
(side note...  Interco is the manufacturer of the 39.5" IROK tires that I have on the Heep, and they are on 16.5 HMMWV wheels that I run specifically for the DOT approved double bead lock... --think: 3psi, no worries about blowing a bead--  They are one of very few that know that a nice chunk of their business is still in the 16.5 size...)

Speed, run what you brung for sure... just know that the next set may be more difficult to find...  Overall dimensions...  If I remember correctly, the 225/70-19.5 wheel/tire at pressure are about 31 inches...  (by the numbers, should be 31.9in diameter) The 19.5's that many of us are talking about here are 3500HD specific...  they are 10 lug with a 7.25" diameter pattern... (pronounced: "wacky @ss lug pattern")  There are 8 lug 19.5 wheels... 8 x 6.5", just like your 70's 1-tons... Many here chuckle as we refer to those wheels as "Frito" 19.5's as they were pretty popular on the Frito-Lay (registered?  ;D) box truck (aka bread van, aka whatever else...  seems like different regions of the country called them different things...)  

Someotherguy can provide some first had info as he was running Frito 19.5's on his last green crew wrecker...  may she rust in pieces...  ;)

   That'd be a huge help;I thought the 19.5's would have a diameter enough larger to make my 4.10 axle a little happier on the highway,but my 16's are right at 31 inch diameter,and I think the 16.5's are about 30 inches. sounds like it wouldn't gain me much to switch to the 19.5's. (I guess if it meant THAT much to me,I could work up a set of those adapters and switch to 11R-22.5's;that'd give me a diameter of around 44 inches! Of course,I'd have to take the fenders clear off to have room for 'em.) I was also thinking about an NV4500 conversion until I saw what they're selling for...Never Mind!! But-who knows,maybe I'll find a free truck with one in it;hey-I was given a 1957 GMC 2 ton dump flatbed for free,so it could happen! (Damn! I guess I'll have to post pics of ALL my projects and toys!!)

You won't gain a thing my going to 11R22.5-24.5's but broken axles and smoked transmissions ;) . . .

19.5's come the same load ranges F, G, and H  ;D !

8-19.5 = 34.25" tall

8R19.5 = 33.5" tall

245/70R19.5 = 33.3" tall

225/70R19.5 = 32.5" tall

7.50-16 = 32.2" tall

9.50-16.5 = 32.2" tall

tall 235/85r16 = 32" tall

9.50R16.5 = 31.8 tall

Radials seem to run shorter then the Biasply's . . . But using the listed measurements you'll find the right 19.5's for you . . .

Direct bolt wheels can be had as cheap as $50 a rim . . . $120-$160/tire to $175-$225/tire tho . . . but they live 60,000 -110,000 miles.

I run Mudder's i get 60-75,000 miles from a set . . .

Oh and if you really want there is a few brands offering 19.5's in load range J  ;D . . .

F = 12ply G = 14ply H = 16ply J = 18ply  M =  20ply  :o

                    "19.5's in load range J"
       And THAT'S where we start breaking hard-parts..... ;)
    I'll have to do some number crunching and see what 1.7 more inches of diameter does for the rpms etc. I'm thinking it'll bring my rpms down about 100 or so rpms at highway speed. Not really a consideration. Sounds like price is comparable to 16's,the price of wheels is similar to 16's,and I think availability will be much better than 16's,at least the size I'd run.
 
       I've seen a few of those 3/4 and one tons with the OTR truck sized tires on 'em,and they seem to hold up okay;of course those are "foo-foo" trucks,probably never have to carry anything heavier than a case of beer. :D Be interesting to see how they work in the "real world". I imagine you're right-with any kind of severe usage they'd likely go through wheel bearings,brakes,steering linkage,power steering pumps,etc. The automatic transmissions would have a hard time with the taller-yet overall gearing,and the clutches in the stick models wouldn't last too long either.
