"Sharpen" bar tread?

Recommended Posts

I won't say there is an easy way to cut a tire but if the rubber is under water you can cut it much more easily...Maybe a large carpet knive could carve off the offending rubber..Woody

I cut mine with a regular utility knife (boxcutter) to get the majority of the rubber off and then finished shaping them with a grinder with a 24 or 36 grit grinding disc.

I gave up on a utility knife when I sliced my finger open. Nearly gave up on the grinding wheel when I hit my finger with it and removed a couple of layers of skin. I'm dangerous when I cut tires. Rod H.

I remember seeing on the internet rules for a tractor pull stating no sharpening of bar tread allowed. My question is how can this be done? I have acquired a used set of ag tires and would like to do this, any hints?

There are several ways. Some people use what is known as a hot knife, made especially for re-grooving truck tires. This knife is heated, and melts and cuts at the same time. It is more expensive than most want to pay and does not give a really smooth result. Like most pullers, I use a tire grinding wheel. I purchased one that fits a 4-inch grinder. This wheel is a steel disk with sharp, pointy, tungsten carbide chips bonded to it. It chips the rubber off the tire very smoothly without heating the tire into a gummy state as some other devices do. I also have a small cylindrical tool of this type that I use for final shaping that fits a die grinder. I purchased this from a store that sold supplies for making duck decoys. I got my grinding disk from a friend, but you might try "Midwest Super Cub". I'm sure they will sell them. I have never tried it, but another friend says he uses a belt sander and heavy grit paper. It should work. I also cut one set with a rotary wood rasp mounted on a grinder. Very slow, and only works good while the tire is cold. Gums up when rubber gets hot. Hope this helps. Rod H.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
