Tire inflation pressure

I have a backhoe on my property, that a neighbor has stored for about 5 years. I get to run it around whenever I want to some small jobs. It's a JD 510 Diesel. It's probably from the late 1980s. I had a blow out the other day. I managed to get the tire off the rim, and put in a new tube. I stitched a tear in the sidewall with rebar wire, and put a rubber patch on the inside. I also covered the outside of the tear and stitches with Shoe Goo. I just inflated the tire by setting the compressor to 32lbs, with a lock on connector and with a tie down strap cinched around the middle of the tire. I waited in the house while the tire filled. When I went back the tire beads set pretty tight against the rim, and where there was a gap I hit the sidewall with a hammer. Looks good. My question is, the tires are pretty old and ratty, but I am only running it on soft soil. I saw online that a 12 ply gets 32lbs, and an 8 ply gets 20. Should I run it at 26? Or should I run them softer at 20? I mainly use the front bucket. I really lack skills with the backhoe.
 

Buy a lottery ticket, quick!

Your luck is exceptional, but it will not last. Wire stitching in no way replaces the cord fibers which have been severed. Even a 5 psi blowout can hurt you.

I would stay away from it because the next blowout is coming. It blew out because the tire is in bad shape. You were very lucky getting away with hitting it with a hammer.

Used tires are cheap, new tires are cheaper than a week in ICU.
 
Thanks for the heads up. I got some bad advice from a repair shop. However, the rip I repaired had a patch on it originally on the inside. I found it in the tire after I took it off. You could still see the outline on the patch.
Now I have to try and find a used tire. If anyone has any idea where to find a used tire let me know. I'll start searching online.
 
These days good "used" tires dont exist.Everybody runs em till there is nothing left,or they blow.Buy from your local tire guy.In the end,cheaper than 'online',plus you get service.Online 'saveings will be minimal,plus you pay frieght.And if there is a problem,you're on your own. Help the little local guy,your neighbor, stay in business.
 
A buddy of mine was filling one of his pulling tractor tires, and he just uses a clip on chuck and checks on it every once in a while. He forgot it once, and blew a tire up to 150 psi - it held, but pretty scary - a lot of energy stored up there
