How much is too much rust inside tire wheel rim?

Anonymous-0 · Sep 10, 2011

I just bought a old Brillion cultimulcher that weighs in at 4,700 lbs.It has 4 tires to hold it up.I just recieved 4 new 8 PLY Treadura brand (made in China)6.70X15 tube type implement tires to go on the machine.The rims are 6" wide.When i took old tires off of rims they have alot of rust pits all around them and where the stem comes out of the rim it is thin and not exactly round due to rust.I will oly be using this thing a couple of times a year 20-50 acres each time.I can buy new rims from Shoup's for $54 each but i hate to.If i clean up rims and flake all rust off and paint them inside will they be ok or will they ruin my tubes due to rust pitting?Do they make rubber rim liners for this size rims?

Pour the paint to them, after cleaning with a weld chipping hammer. The holes can be drilled out to round, with a unibit, painted, and then insert a plastic tube bushing, from gemplers, or you could have a washer mig welded inside the rim, then smooth out the edge with bondo. I've done that repair, many times.

Duct tape is your friend! Use it.

I want to second what DIY Dave says. If you don't really beat on them good with a slag hammer you can miss a chunk large enough to grow into the chunk sharp enough to put a hole in your tube.

I had some trailer rims sandblasted. It cost $10/rim to sand blast them and prime them. Lot cheaper than new rims. Of course it could end up showing you alot of small pin holes.

Somebody on here one time said drill a new valve hole in a good spot. Weld the other if it is real thin. Dave

Tap on them until the big chunks come off. Wire wheel using an angle head grinder. Get a piece of 1/8 x 1 inch band iron and bend and fit for new holes. Weld new pieces over the old holes. Go to NAPA and buy a can of rust neutrilizer and spray liberally. You will need two cans for four tires. Buy one quart of truck bed liner paint, also at NAPA and paint each rim twice. I just finished this exact process on two John Deere 4B plow wheels. You will have about $40.00 invested. Ellis Kinney

Duct tape all the rough spots so the tube doesn't chafe.

I had a stick run through the tread of a 6ply F1 on my Allis Chalmers 180 recently. I noticed that tire had a tube and the other was tubeless. Same tire, same rim.

I spooned the tire off to fix the thin, rusted valve stem hole. The tube was there because the valve stem hole was shot. I MIG welded a 5/16" thick SAE washer in the hole and welded the hole up solid. Ground it all down. Then I drilled a new hole 180 degrees out with a Uni-Bit.

I sandblasted the rim after using a grinder and needle scaler to remove heavy rust. Primed and painted rim inside and out. Installed a bolt in style valve stem, mounted the tire tubeless after plugging the hole.

Good as new!
