Tire grooving

In the never ending quest for better traction, how many others out there have done this? Show us what ya got!

Pro Comp XMT, a bit worn with some miles on em.

BTW, the sipes I cut by turning the blade over are visible as well.

Had the Jeep down at Hidden Falls and traction was awesome! These tires have always done well but this little bit of work really helped as well. Especially on the wet rocks.

I opened up the factory groves on my KM2's as they wore out and also added a few more. They now have as good or better than new traction on hard packed snow.

Cool deal!

It sure is amazing what this simple, low cost DIY mod can do for your traction.

This looks like a great way to add longevity to tires. Where can I find a siping tool and, generally, how long would it take per tire? I have 255/70R15 General Grabber AT2s. That's about 29x10 (tread's only 8 and change, though).

I think I picked mine up on EBay for about $65 several years ago.

I'm not to sure it will add longevity at all. Especially if you start cutting away tread. That will actually make the tire wear more quickly.

As for how long per tire, there are too many variables to answer that. Depends how many cuts you are making, what you're starting with.... Typically, not long though. What I did above probably took less than 10 minutes a tire. Now the guys that run the monster boggers that cut out alternating blocks completely, that takes a good bit longer.

I'm looking at picking up some TSL/SX's, looking for ideas on those. I know lots of people cut those, is there anyone on here who has? Looking for more pics and tire porn!

It may not add to total longevity of the tire (i.e. - mileage before bald) but I feel that it greatly increased my usable longevity. My KM2's were starting to get pretty slick on hardpack snow as the separate tread blocks were becoming single, large tread blocks. Using the groover to renew the grooves in the tire and give me more, smaller, biting edges will let me get a few more winters out of them before they get sold off or become summer-only tires.

I agree that any time you remove rubber from the tread you are reducing the total number of street miles you will get out of the tires. For me, that wasn't a concern.

Oh yeah, it took me 15-20 min per tire at a very leisurely pace to groove my tires.

That looks factory, and what BFG should be doing in the first place. If I had KM2s, I'd copy that.

Oops, meant to respond to John82601.

I might be trading for a set of TSL/SXs tomorrow. Hoping they are in decent shape to have a new set to carve up.

The TSL/SX deal fell thru. They were 13 years old! Dam!
