I am looking to get a tire knife and start making some "Cut" tires out of my Ground Hawgs, but which one should I get? I know someone has tried this and I have heard some horror stories about doing this! Please let me know
Thanks Redman

Its more 'how much do you want to spend'?

Rilfit's are nice, but pricy. Ideal knive's are relatively cheap, but take longer.

I have an ideal knife, I've done two sets of tires with it. For the once every 1-2 years I do a set, its no biggie to take longer, rather than spend a few hundred on a nicer knife. But it might be a good investment for a club.

Figure about 30 minutes per tire or so. Depends on how much you cut from each tread, how deep, etc.

tips for making it go faster:

1) Work on a hot day in the sun, if possible
2) Having a powerful halogen work light nex tto the tire as you cut can preheat the area as well.

(rubber cuts better and cools the blade less when its hot)

3) cut shallow cuts, and make a 2nd pass if you want deeper. I find 2-3 shallow passes is easier than 1 deep pass.
4) Cut slow, don't force the knife or the blade won't last too long.
5) If you don't have any more blades, slice the edge off a ulitity knife and use a small torch to heat/ bend it to the shape. It'll last much longer than the blades that come with it.

Personally, if you are going to do more than one set of tires, the Rilfit can't be beat. I did a complete set of 36" Swampers (Q78s, actually) @ 18minutes ea. The blade had already been used on 3 sets of tires (36- 38" diameter) and still cut the Qs like butter, all deep (The Q78 has a 27/32" tread depth, and I groove my tires when they are brand new and full depth), single pass cuts, 35 degree day. When I say "like butter", I truly mean it- no effort whatsoever. The only thing that required effort and slowed me down was rotating the tire- I could have cut 5 minutes off my time by having the tire mounted on a spindle mounted to a table. Mine were just sating up in a corner of the garage. The Ideals are a TON more work, IMHO.
