Siping Truck Tires
Posted by Tim on March 17, 2006
I am a Fleet Administrator and looking for data concerning the practice of tire siping as it relates to extending the life of the tire.
Goodyear's position on siping is that it may, under certain operating conditions, improve tire performance. In particular, traction may be improved in wet or winter condtions. However, under the vast majority of truck operating conditions, new tires are designed with tread patterns and compounds that do not require siping for satisfactory performance. From a treadwear standpoint, there are some cases where siping has helped tires wear more evenly. For more information on siping go to http://www.goodyear.com/truck/pdf/radialretserv/Retread_S12_V.pdf This is Section 12 out of our Radial Truck Tire and Retread Service Manual and includes a few paragraphs on siping.
