<font color="yellow">Sawzall.

No... I'm not kidding.

I did it with a sawzall and a metal cutting blade to my old set of P78-15 (33x10) Buckshots I had on steel wheels. It worked GREAT. Leaves a cut about an eighth of an inch wide, whereas the heated tire-knife leaves cuts too small to see until you put some miles on them. After my friend saw how well it worked, he borrowed it for use on his 35" Boggers.

Use cuts parallel to the side wall (prepindicular to the lugs of a bogger) to get them to flex - his flexed like MAD after we did that - they distorted around rocks at 12 PSI like they had before at 5.

Use a long blade and go 1/2 to 3/4 of the way through each lug, and try to vary the pattern. We were really tempted to cut the small lugs off the Boggers, but they shake the truck like a paint-mixer as is...

I mentioned to him that we shoul double up the blades to make some 1/4" cuts - so that it would actually provide traction in the mud.

The siping makes a big difference - I only did the center tread of my buckshots (they have an un-interrupted zig-zag all the way around the tire) into SX-Swamper-type V shapes. He went crazy on his boggers and cut each big lug twice and the small ones once. Makes a huge difference inthe flexibility of the tire and even more in the road handling.

Keep the cuts on the big lugs that have the sidewall tread at least an inch from the edge of the tire - he got too close with a couple and ripped a couple tread blocks off at the cuts. Still would do it again if asked.

Hope it helps <IMG SRC="smilies/biggrin.gif" border="0"></font>

Buy a tire grooving iron. Tips vary in width from like 1/8" on up to 1" wide cuts... About $65 from various places, They even sell them on www.mrtrockcrawlers.com


I used my grooving iron to groove my boggers - worked great <IMG SRC="smilies/smile.gif" border="0">

Oh yeah - to "sipe" and not "groove" with the iron, simply turn the razor drag wire around so you make 2 "sipes" per pass... <IMG SRC="smilies/smile.gif" border="0">

Hmmm.... $40 to sipe 4 tires ONCE, or $65 to sipe AND/OR groove any tire you own for the rest of your life... tough call <IMG SRC="smilies/rolleyes.gif" border="0"> <IMG SRC="smilies/wink.gif" border="0"> <IMG SRC="smilies/tongue.gif" border="0">

Time is money, time is more building. I would rather be adding stronger parts to the rig than cutting tires up. Out of curiosity how long does it take per tire with the iron?

If time is money, then money is time - silly arguement... To have mney you have to WORK, which means less time building your rig - so you lose time either way - but buying the groover saves time AND money in the long run...

Once you are comfortable with it - you can sipe a whole set of tires in under an hour.
