So I have heard arguments both for and against siping your tires. I understand the benefits especially on slick rodes to get more traction. What is everyones experience on the benefits and drawbacks. Does it shorten or lengthen the life or your tires?

Done properly, there is no disadvantage to siping tires, only advantages. Properly siped tires run cooler and they typically actually last longer. Many factory tires come siped from the factory and they certainly would not sipe tires if it could cause problems for the tires.

The only real caution is if you do have your Mud Terrain tires siped, which typically have four tread blocks across the face, is to only sipe the two center rows of tread blocks. For rock crawling and other extreme level trails, that leaves the outside tread blocks unsiped to leave max strength where it is needed the most.

I've had two sets of MT style tires siped and really liked the results.

I had the OE Michelins siped on my pickup. I think they grip better and seem to be wearing well at 28,000. 1-ton 4X4 diesel.

I've been siping all my tires for some time now. The only input I can give is that when I drove alot on big, sharp rocks, I found that it took some chunks out of my tires. I was using Toyo MTs and was way too heavy on the gas pedal...I'm older and wiser now and haven't had any problem. Like Jerry said, I've found they seem to last longer being siped. p.s. I know...the picture has A/T's on my Jeep. I'll be changing to M/T's when these wear out.

Thanks Jerry I would never had thought about that with M/T's. I have the KM2's but haven't run them on slick roads yet. So maybe I will get them siped. At $200+ a tire I will do anything to make them last longer. Plus with my slick roads in Idaho anything to improve my traction will help.
