I have Goodyear Duratracs with 40K miles. When new these were awsome on ice, now that great traction has dropped off a little. The tires, when new, had about 3/4" tread. Now, after over 40k miles they still have a lot of tread, but the tire sipping from the factory is starting to dissapear. Can I just take an exacto knife with the straight (square) end and just push the knife into the tread where the sipping is to make it deaper? I will not go beyone the wear indicator height. I would plan on just making the existing sipping deeper. Treadwear right now is nearly perfect, so I expect Ican get another 40K miles comfortably, maybe 60K until the wear indicators.....but I never go that low if I use the tire in the winter.
Would it be helpfule to heat the knife blade with a blow torch?
I knw that in Canada you can go to a tire dealer and they have machines that cut across the tread to add sipes.
Comments or suggestions?
