Just went in to have my tires rotated, and rear drums checked, and the guy talked me into siping my tires. I've read about it and had already thought about it, so it was an easy sell. Having done my research, I'm now in the process of determining if it'* all it'* cracked up to be.

On a side note, I'll be doing rear brakes soon. My right rear brake cylinder is weeping, and my pads are more than 50% worn.

More info on siping, and I'll post my results when I get some more time behind the wheel:

Alot of tires are like that from the factory aren't they? They only last a few thousand, but now your just put it back on, right?

How much did it cost you per tire?

How much could you really increase traction by. Im guessing this is gonna vary by tire.

Agreed...

If only you knew what wren pays for....

But I don't want to know...

If you guys saw that link, it'* the best explanation. I paid $11.50 per tire, well worth it. With the added power I have this winter compared to last, I really need all the traction I can get. Stock tires have what they call 'molded siping', but you really have to have the siping cut to be effective.

It adds traction (especially wet), improves braking (especially wet), increases lifetime of the tire by helping it cool faster, and the siping is nearly 1/4" deep, so most guys end up doing this twice through the lifetime of the tire. They'll only do it if you have 50% tread or more left. I'm impressed so far with dry traction, waiting for more rain.

Ok...apparently the nearest siper service place from me is 162 miles. Unless the local dealership is able to do it.

They are all over the cities. if it actually helps traction, then it definitely couldn't hurt here once the roads get iced up.
