I've read on here about siping tires, which seems like a cheaper way to gain traction with my stock tires instead of going to buy a whole new set. Someone had mentioned in a recent post that you could have it done on all 5 tires for like $100.

Today I was at my local tire shop, and while I live in a rural area of South Jersey, this is a full-service tire place with years (decades?) in business here. I asked about this, and the owner told me that they used to see a lot of siping on tractor-trailer tires years ago but he hasn't seen it recently. And that a special machine is needed to do it and he doesn't know anyone around who has the equipment to do it.

Can someone shed some more light for me? Is this process most tire centers should be able to do? Or do I need to find a specialist-tire shop?

Thank you. :dance:

(If it matters, this is my year-round daily driver. I was looking to have this done to increase winter traction and also for some "light" off-roading, as these are the stock all-season tires. My next new set will be more formidable A/T tires, but that's a different discussion thread that I've already taken part in on this site. Thanks.)

wow, they do it at all the tire stores here in the northwest. It costs like $12 a tire, cheap insurance I always figured so I do all my tires. It does take a special siping machine but it is really fast and done in no time.

Here in Wisconsin the Matthews Tire and Auto sells 2 versions of most winter tires...siped and non-siped. I was looking at a whole stack of em, different brands and sizes, made into a Christmas display when I got my DuraTracs mounted a few weeks ago.

DuraTracs, by the way, come from the factory siped.

Really? Did not know that . . . . I confess I have no idea what siping looks like, despite having spent an unhealthy amount of time admiring my DuraTracs. :whistling:

Most tires have enough factory 'sipes', or slits, in the tread blocks to offer great all around traction. Those tires with large blocks of rubber (think: bug mud tire) can gain additional traction by siping. However, the added slits in the rubber also will 'chunk' when wheeling, especially if you spend a lot of time in big rocks. I run 37 BFG Krawlers on my YJ, and have siped the center lugs, but leave the outer lugs whole. I find it really helps with snow and ice wheeling, especially at 2 or 3 psi. The sipes seem to bite better into the ice. I also think this helps with street driving, at normal pressure (20psi), as it gives increased traction in rain.

Up here, Les Schwab is the company I used for siping. They're a national chain, but not sure if in your area.

I'm NOT an advocate of siping an 'all around' type of tire, as I think the added cuts will decrease tire life span. "They" say it doesn't. But I don't believe that. I weigh the 'increased traction' -v- the 'shorter lifespan'.

I wouldn't think the all-seasons would benefit all that much from siping. Very different from an MT with flat tread blocks. But I confess, I have never had an all-season tire siped so that is just semi-educated speculation on my part.

I did, actually. Found out by accident while reading a buncha reviews on some tire site. One of the deciding factors for buying them.

Siping is the tiny little cuts between your treads (don't know how long you've had your tires, or how long the siping lasts) that look like little teeth. It also includes the larger squiggly lines, which open and close for better grip as pressure is applied across them. Pinch one of the lugs with your fingers, and you'll see what I mean...if you've got enough tread left.

Ya know, I'm not sure but ... technically, aren't sipes just "cuts" whereas that is more of a molded "groove"? Nitpicky, I know, and I'm not even sure.

Yeah, they actually come in a number of different patterns, from what I understand. According to the shop where I got my tires mounted, any kind've cut that "moves" with the weight of the tire qualifies...different tire manufacturers have different styles. I think the ones that are put on the tire after the fact by a machine are pretty universal.

All I know is the DT's grip most surfaces like they're wrapped in sandpaper. :D

I did see something to this effect in Consumer Reports. But then again, they're the folks who say that Jeeps are crippled POS's that won't run past 500 miles on their unreliable engines. So I'd rather trust issues like this to the people on here. :D

Had my stock BFG MTs Siped this afternoon at Les Schwab. $12.50/tire x 5 = $62.50. Rotated at the same time for free.

Siped just the center lugs, which is what they recommend.

The only drawback to the stock Rubi tires is the not-so-great wet and ice traction - and that's exactly what Siping is supposed to improve... Hope this will help!
