I am repairing a 13.6x38 tractor tire tube. This is an older tube, Good Year made in USA, good rubber. It only has one previous patch, and that it where it is leaking. Not at the edge but in the center of the old patch. What's the best method to repair this? The old patch is still adhered very well at the edges. gobble

I would put a much bigger patch over the old one, or better yet, put a new tube in it.

that all depends on how big the patch is. if it is small use a bigger patch over the whole thing. if its a big patch use a smaller one so the old one still has its edges.

I may be totally wrong, but if it's leaking at the center of the patch, there might still be something in the tire that's punching the hole, thorns will do that sometimes. They break off and then work their way on into the tube with use. Just my thoughts, Keith

If the patch sprung a leak in its thickest area, I would be looking inside the tire for a cracked casing. Radial tires, for example, often cracked along the ply edges, and start nibbling at the tube. Only fix was patch the crack to protect the tube. Or possibly, whatever caused the former puncture only got partially removed.

An old tube patched is probably much better than a new tube. The new ones are a poor grade rubber.

Thanks everyone, its on the inside of the tube, which leads me to rim chafe maybe. Will go with a larger patch as this one is an inch and a quarter or so. Of course replacement is always an option but then I'd end up with a lot of tubes around here with one hole in them lol......gobble

Depends. I think a guy can buy better tubes IF they're willing to pay for them

Firestone had 2 different tubes that fit my 38" rims.
One imported, the other USA made.
Per the spec sheets, the USA tube weighed 3-4lbs (don't remember exactly) more than the import...and cost another $25.
As I didn't want to do this again real soon, I went with the USA made

Were it mine, and if I had a decent small grinder, I'd remove the old one myself. Since I don't, I'd take it to the tire shop and have them grind off the old patch and replace it with a little bigger one. I'm not nuts about the patch over patch deal. gm

Grind old patch off then replace with new patch. Will be fine. I would use a bigger patch though, as sometimes the bigger patch to a point is a bit thicker. Look at your rim it may have rust causing you rproblem. I would wheel off the rim to remove most of the rust and flaking/scale. Paint and replace tire and tube on rim. Reload if wish and go for years to come.

then yes a bigger patch over the old one. i sure dont know how you guys are talking about grinding the old patch off? not going to happen , only tear up and have a bigger hole. even in tires with a cut,... they install a smaller patch over the cut then a larger boot over that. and if its a chinese tube you go with they are half the thickness of a firestone or good year tube. and no way i be put fluid in them . perfect case of u pay for what u get.

Tom. I have gone out and taken a tire apart and found that several times. If that tube has a split under your patch , replace the tube with a heavy duty radial tube. If the tube has split, Most of the time the old tube will continue to split and will eventually split out under your bigger patch. You do need to carefully remove the old patch so you can see just what is happening under the old patch. Speaking from experience here.

replace the tube it is all stretch out and when you put it back in you will get folds and in time it will fail
