Traction $13.00 + 1 hour = EXCELLENT traction on ice!!!!!

[Wal]

From my brief experience with my "screwed up" tires, I would say it is not neccesary to leave the screws slightly unscrewed. I got VERY effective results with them screwed all the way in. I would be afraid the head of the screws might tend to "snap off" /forums/images/graemlins/blush.gif if they are extended. I don't want to do "vice-grip surgery" to get headless screws out /forums/images/graemlins/shocked.gif

re:
just the question i was going to ask. but leaving them sticking, would that not make them more liable to expell from the tire?

Not really. When you got a 5/8" or 1/2" screw you still got plenty of thread inside the rubber. Hey, if they didn't come out racing motorcycles they should not come out on a slow moving tractor.

A lot of tracks banned this setup because they gave way too much traction. I can remember one time at Ft. Devens the tech inspector made me screw every one in all the way before I could run the final. Good thing I had a battery operated drill.

BTW, the screws we used were #7.

Of course, Wal, you realize that you have now opened the door for everyone to call you...... Screwy Wal ! /forums/images/graemlins/shocked.gif /forums/images/graemlins/grin.gif

I would be concerned that with any significant amount of driving on pavement or concrete, the screw heads would wear off, flatten, or otherwise deform such that removing them becomes a very difficult task.

It might be better to just plan on leaving them in. When they wear down such that they are no longer effecitve, just put some more fresh ones in.

For shoes, I have found that a simple office stapler can do a pretty good job of increasing traction on ice. In high schoool, we once caught a guy cheating at broomball during phy-ed class that way.

Motorcycle weighs a lot less than a tractor too. I'd screw them all the way in /forums/images/graemlins/grin.gif

I'd screw them all the way in too. The point I was trying to make was that you get much, much more traction if you leave them out just a little. I never advocated running screws on a tractor that were not in all the way. However, you can also get more traction by adding more screws.

As for the screws wearing down, I ran 3 seasons on the ice, probably 30-40 race dates in all, and the screws were only slightly worn. The hex drive bit still had no problem removing the screws. In fact, I still have a coffee can full of used screws that I occasionally use for stuff around the house. I'm sure running on concrete or asphalt will significantly reduce the lifespan of the screws.

Rick,

Luckily, I ONLY operate my tractor on either dirt or our gravel road. The only concrete would be my barn floor /forums/images/graemlins/cool.gif

Wal,

Glad to hear of your success with those screws.

I could not help but think that you might still be glad you have those chains if you have slopes you want to work the tractor on when it is wet in early spring or later fall.

In mud, those chains will surely give you traction where the screws will not. Right tool for the job, so to speak.

Don't know what your needs are, but you may find a time in the future that you are happy you have those chains! Don't feel too bad about not being able to send them back... /forums/images/graemlins/smile.gif

Hummm...I could not find the duo-grip style chains for my B2910...tire size is just slightly different from the B7500...wonder if they would fit my b2910...where did you say you lived? /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif

Heh, heh . . . . .oh it looks like its about 650 miles or so from me to you /forums/images/graemlins/grin.gif. Just an easy one days drive /forums/images/graemlins/tongue.gif.
Seriously though, you may be very right about the chains being useful in the mud and muck. At least, thats what I'm tellin' the wife /forums/images/graemlins/wink.gif

My wife and I went to the Sapporo ice festival in about 1993. ALL the cars there had 4 wheel studded snow tires. The streets and sidewalks were not cleared of snow and ice. People just walked and drove on it. No chains on any of the cars.

I don't like the clonk-clonk with the chains, and I definitely don't like them catching on non-moving parts.

I called and ordered the 4 ag tires today and plan to stick 2 screws in each lug when I get them. I'm also getting new rims. So, when it's high and dry (sometime in the future; hasn't been for near a year around here), I'll put the turfs back on.
