  The trans. is a plain ol' SM465 and the axle is a 4.10,I'm pretty sure.

SM-465 + 4.10's + 70mph + X-/R 19.5's = X-rpm.

225/70R19.5 = 70mph@3,000rpm.

245/70R19.5 = 70mph@2,900rpm.

8R19.5 = 70mph@2,850rpm.

8-19.5 = 70mph@2,700rpm.
...

9.50-16.5 = 70mph@2,900rpm

7.50-16 = 70mph@3,000rpm.

235/85R16 = 70mph@3,100rpm.

9.50R16.5 = 70mph@3,200rpm.

Don't for get most GM V-8 gas engines will maintain 3,250rpm all day long . . .

GM gears the truck's with out an over drive to cruise 2,900-3,100rpm in high gear . . .

so your maximum safe cruising range would be 68-72mph, with 16-16.5 your running 2,900rpm-3,200rpm with 19.5's you'll be running 2,700-3,000rpm . . .

I hope this help's you ?

Mike

 ;D ;D That helps me immensely,Mike;
    I'm seeing that changing to 19.5's just for the sake of changing wouldn't buy me enough improvement in road speed,rpm reduction or gas mileage to be worthwhile. If,however,I need to replace tires anyway,19.5's are a very good choice-they average the same rolling diameter I have now,the change in size of tires and wheels is the same cost as a switch to 16's would be,and it sounds like they last considerably longer than 16's and 16.5's. Now-what kind of lugnuts would I need for the 19.5's? currently,I have 9/16 NF tapered seat lugnuts with the factory torque plates.(I think) Reason I ask is that when I trained tire installers for Sears,years ago,a guy came in and bought a very expensive set of wheels and tires,but when he brought his car in to get them installed,we discovered nobody made lug nuts that fit his car with these particular wheels. Of course,later on it wasn't a problem,the wheel manufacturer offered lugnuts that would fit anything but a knock off hub,but back then we had to go with an alternate choice,and worked a deal for him on the first choice when all the parts were available.

if you get 19.5 rims that are alike same lugs will work . . . If you have steel wheels them get steel wheel's if ya got alloy's get some alloy's . . .

pretty much regular old nuts will work on 19.5's unless you get some fancy ones requiring Mag lug's . . .

your not really saving much on over all RPM/MPH slightly but nothing great, your gaining load carrying your gaining tread life your gaining handling all of which add's up to safety.

now instead of using 90% of tires payload your using 70% of its payload you just reduced tire failure 20% which increased your safety aspect 20% . . . and so along depending on load range you end up going with.

I blew a set of duel's on dually truck running 16's it took all had to get the whoa'd back and set down i stop 3ft from a car with 3 kids playing the back seat  :'( !

After that i was towed right the tire shop and had it swapped over to 19.5's within few days every truck i had was rolling on 19.5's  ;D

You won't ever catch me owning a light or medium duty duel rear wheeled truck with anything but 19.5's  ;) . . .

  I'm really liking the idea,but I'm on an SSD fixed income that's about $100.00 less than my house payment and utilities run every month,so anything I do outside of that requires some sort of trade-off;sell a car,do some outside work,do some recycling,haul some scrap metal. What I may do is change over to a size the same diameter I have now,and do 2 wheels and tires at a time until I have a full set. With the tread life I'm seeing,I should be able to have a full set on the truck BEFORE having to start replacing the 19.5's! :D
   My 16.5's still have about 80% tread left,so I probably won't have to worry about tires for a pretty good while. (That reminds me-I should probably work up a spare for this truck.)

where do you guys get 19.5 tires for $120?

tirerack lists 3 in 225/70/19.5 at $228, 239, and 308 per tire.

if i can pick them up for $120 a tire i'm switching to 19.5 wheels when my 235/85/16's are worn out

The only $100-$120 19.5's you'll find are garbage not worth spending money on, and you can bet on that!  Made in china, sometimes "new", sometimes retread, and absolute CRAP.  Believe me as I am speaking from experience, several sets of very bad 19.5's that my cheap-ass former boss put on the wreckers.  You'd almost be better off with 16" load range D maypops from the used tire store.

If you want good 19.5's you're laying out $200+ ea; if you want killer ones, $300/ea.  They're worth it, it's just a hard nut to crack especially in these rotten economic times.

I have bought many made in the USA 8-19.5 Mudder's or Firestone Super All traction's, General Super All Grip's, Good year Custom Extra Grip's, and some off brand USA made tires called Premium Traction Grips . . .

All of which lived 60-65,000 Miles without getting stuck and or blowing out for $110-$130 a tire.

there 4 separate 19.5's in the $110-$130 a tire all of which where made in the USA that where not Recap's that preformed flawlessly . . .

I also bought many radial tires for $150-$175 a tire that too performed flawlessly MT's, MTR's, and DH01's went 70-75,000 miles. actually the DH01's went 80-85,000 miles a set.

I bought thousands of them both, most time i bought 18 tires at once . . . some times only 6 or 12 . . .

   Thanks for all the info! ;D
    The wheels look like a pretty good deal,but the shipping might be an ass-kicker ::). I've emailed the seller to see what it'd cost to send 'em out here. I'm still thinking unless I find a wrecked Frito van I'll probably have to do this a little at a time. BTW-just the TIRES would cost a fair hunk more than either of my Duallies is actually worth :o. These trucks would only be worth the expense because I'm really fond of the trucks-they're kinda like the kids I never had,only they don't have parties in my house when I'm away. :D..

Mike, please, if you're going to post information let it be complete.  How about some links to places these specific tires can be bought, so that the information is truly helpful.  Thanks!

So...Mike?  No links to these cheaper non-chinese tires to help everyone out?

On a side note, been down to the scrapyard a half dozen times now in freaking SOUP mud and these Goodyears haven't got me stuck yet.  I feel really nervous saying it as I'm sure it's just a matter of time; I'm sure I've just been lucky and driven carefully.  Sure am blowing a lot of money at the car wash each time though, since I refuse to let the mud stay on the truck...and it's a LOT of mud.

Richard

At least it's warm enough to wash your tires..I have a brand new New Holland tractor that has been going through the frozen ground and hitting some serious mud this last week. I'm about 4 weeks from turning on any running water to wash anything! The mud freezes up and breaks off the next day anyway.

OK, the Treadwrights are retreads, and the Denman is an 8R19.5 which is like a motorhome tire, tall and skinny.  (and is $175, not $110-$130)

Your statement was "there 4 separate 19.5's in the $110-$130 a tire all of which where made in the USA that where not Recap's that preformed flawlessly . . "

If we're going to restrict it to 8R19.5 then that isn't very useful to a lot of people.  The most common size used on these trucks is the 225/70/19.5; it's the stock size on 3500HD, stock size on the Ford F450SD, and I am fairly sure stock size on the new Dodge 4500, etc.

I'm really not trying to be argumentive here but when providing info that should be helpful to others the information needs to be complete - if you say the cheap good tires are out there, links to them should be included.  When the details come out and we're looking at retreads and less-used sizes...not sure what to say.

If I have to be more specific, I'll ask it this way: inexpensive (under $200/ea), not retread/recap, not made in China, Korea, Slovenia, India, or any other place like that, common size (225/70/19.5) - readily available - preferably from a recognized manufacturer - with specific info that needs no blanks filled in on where to buy these tires?

This info would help practically everybody on this forum.  The bad part is, I don't believe the tire exists.  I will be very happy to be proven wrong, because it would only be good news for all of us.
