what kind of rubber?

[72longhornII]

I recently brought home my Dads 72 c30 longhorn and among some of the problems that come with a truck sitting for several years (slips, misses, and some rust) i got dry rot on the tires and I'm looking for good tires for a 72 one legger 3/4 ton

[kcsa75]

What's a "one legger 3/4 ton?"

[jocko]

good question? non-posi?
Welcome to the forum 72LonghornII, would LOVE to see some pics of your truck, gotta love a longhorn!
A great tire size for your truck is 275-65-16 if you have 16" wheels. If you have 16.5" wheels (more likely), then 9.50x16.5 are a good choice. I've attached a few pics for reference so you can see what they look like. The white truck has the 275-65-16s and the green truck has the 9.50x16.5. Both are Firestone TransForce HT's - the 16.5 wheels have a few less tire options, but the Firestones are still around.

EDIT: TYPO CORRECTION: The tires on the 16" wheels are 265-75-16 - I swear I'm nto lysdexic... Sorry for any confusion - thanks Sideways!

One legger = non posi. It has transforce on it now, I just don't know enough about the truck to pick out tires for it without some insight.

I put these on mine a couple of months ago, so far so good! 275/70-16's http://www.treaddepot.com/tire/15486...FSISMwodp3EApg

On your white truck you mention 275/65-16" ,I have seen 265-75-16"but not the ones you mention.Are they hard to find?

[jocko]

DOH, I'm so sorry - thanks so much Sideways - I DID write 275-65-16! I've corrected in the above post also, just in case someone only reads it. The size on my white truck is 265-75-16. Great catch, sorry for the typo. there's no gouge like bad gouge...

[SS Tim]

So just to clarify, is your truck a C30 (1 ton) or a C20 (3/4)?
A Custom Deluxe or a Highlander maybe?

Are you sure you have 16" wheels? Mine were 16.5, and the truck came with 5 new tires that are pretty much unused (and I'm only keeping one as a spare).

[72longhornII]

C30. I forgot it is a 1 ton custom camper he just had it rated 3/4 with the state. I'm not real auto savy, my dad always did the work, since his passing I've got to learn on the fly.

[SS Tim]

Cool makes it easier when we know.
The Longhorns were built on the slightly longer wheelbase 1-ton frame in both C20 and C30 versions. The prime difference being the axles and springs between the two.
Since you have a C30 it would have the H072 rear axle rated at 7200 lb. Being an open differential (one-legger) is kind of hard to overcome as the only drop in is an expensive out of production No-Spin locker or with axle modifications, a 14-bolt Detroit locker.

Sorry to hear about your Dads passing it is a difficult way to learn. But the links I posted up in #8 will give you a good start and a factory driver's handbook (manual) is a good thing to have and read too. Reproductions are readily avaliable if yours is missing.

Since it is a C30 now I'd really like to see the SPID! :-)

Thanks, my dad was a member til his passing (dwaite72lnghrn). I have a mechanic friend that said he'd help me but for the sentimental value I'd like to do most work myself.

must have more pictures!! nicely equipped camper rig ya got there. Custom Deluxe also, was looking for the interior trim color. Don't see it though! Love to see the seat, or, the whole interior for that matter.

[72longhornII]

The interior was redone about 6 yrs ago so it's not factory. Neither is the motor, the 400 was swapped out with a 502 around the same time. I'll take some pictures of the inside after I get off work and post them.

Found this thread with some background, apparently it was his Dad's as well. Too cool. Unfortunately the pictures will not write for me. http://67-72chevytrucks.com/vboard/s...ad.php?t=25644

Baltimore trucks generally did not have a trim code. However Highlanders did from my examples so its probably a standard Custom Deluxe.

I remember your Dad well, he has been missed. I am so happy to see you join and keep the longhorn. That is simply awesome. Hope your Mom is doing well, we met at a board meet years ago. Good people, so happy to see you posting.. If you need any help with the site n such message myself or Josh anytime.
