View Full Version : should I sipe my tires? alphe 10-31-2007, 04:22 PM I got a flat tire the other day, and when I went to the shop they told me something regards on how I would benefit for having my tires siped. Is it a good idea to have the tires siped?

I dont agree with the nitrogen inflation. This is actually proven to be beneficial. Nitrogen is less susceptible to thermal expansion. It also is drier. Even using clean, dry air w/ a water separator will still allow water in the tire. On airplanes we use nitrogen for those reasons. If it is unavailable we can use compressed air, but here is the catch. We have to change that tire at the next available location. If I had the choice/option of using gaseous nitrogen to service my tires I would. Obviously this is only my opinion, and you know what they say about opinions and a$$holes. Everyone has one. andysinnh 10-31-2007, 05:33 PM Siping - a godsend during the winter - the set of winter tires I just ordered from Tire Rack for the Freestyle is Ultra-siped (Bridgestone Blizzak WS-60). But it only really works if the rubber is made for a tire with siping (proper flex) and that the siping goes all the way to the base of the tread. "Aftermarket siping" by dealers is just a bandaid for a bad tire design for inclement weather.... Nitrogen - good theory, as long as you can guarantee that the entire tire is full of Nitrogen, not a mix of regular air with it. The only way you can be assured of full-nitrogen tire fillups is if you can somehow purge the tire airspace first - and th eonly way you can do that is with 2 valve stems....... Not worth the effort, IMHO. andy Bill 10-31-2007, 05:35 PM Here is Consumer Reports take on siping: "The practice of siping, or cutting extra slits into tire treads, is supposed to improve a tire’s snow and ice-biting ability. Tire dealerships typically charge around $15 or more to sipe tires. To see whether siping makes any difference, we tested two performance all-season models, an H-rated Michelin Energy MXV4 Plus and a V-rated Michelin Pilot Exalto A/S, with and without siping. The siped version of both models showed modest but measurable improvements in snow-traction and ice-braking performance. But braking distances on wet and dry pavement were a few feet longer. Besides costing $60 or so for a set of four, having your tires siped potentially voids any tread-wear warranty. We don’t think the modest gains are worth the extra costs." digitalh3lix 10-31-2007, 08:46 PM laser cutting.. ive heard good about em, but i dont know anyone who has done it. alphe 11-01-2007, 02:44 AM i see... thanks everyone!!! it seems to be unnecessary then haha!!! good to know that~ |
