Hell, I live in the middle of OREGON. I've got 4 shops in town that do it, and another 5 in town 15 miles away. Most major tire retailers will have a siping machine.

The only people I wouldn't suggest doing this to, would be someone who lives on a gravel road. Not reccommended.

Well i found 4 places in mankato. so it'll run about 50 bux? Do you believe the "greater tire life" they pronounce?

My car is definetly beginning to see some traction problems, with all my mods

But seriously, Chicago winters are the worst for ice on the roads. I think I will get this done.

Including mounting? Do you happen to remember the total for the bill, Bill? :?:

The place that siped my tires is the place I bought them from last year. They also hold the warranty on my tires. So based on that, I'd believe the longer tire life, or at least not shortened. They wouldn't do anything that would decrease tread life or damage the tires.

No mounting or dismounting involved. They do it on the rim. My rotation was free, but even if the tires hadn't been off the car anyway, the price including removing the wheels from the car and putting them back on. Just the 11.50 per tire, times 4. No other charges.

Well, the jury has reached it'* verdict, as it rained hard this afternoon. The first 'spin' I got caught traction earlier than I'm used to, and REALLY hammered us into the seats. Cornering wet is improved, as well. This was worth it. Easily. Just for the wet traction improvement, not to mention the other benefits.

wouldnt it be more wear on the tires... because its not solid... and things that arent solid brake off..

No, it decreases tire wear by cooling the tires faster. Go check out that link.

If a city needs a siping machine it would be where i live with all the snow and ice we get during the winter. The closest shop is 95mi from where I live.
