Siping?

Siping tires originally came from the Nordic countries where ice is a standard condition for a large part of the year. Bandag brought it to the trucking industry on a cap they named Bandatrac for increased winter ice performance allowing the blocking more flex to bite the ice and were successful. A trailer tire will benefit from the same process under those identified conditions however the down side is reduced tire wear and tires that are prone to free wheel skip wear will faster. Marathon, Marathon, Marathon........are not used for any purpose in commercial applications nor are the proprietary tread designs so highly regarded on the tire. A siped tire is only going to squirm as much as any other tire with a flexible block design like winter grip tires. If you are used to driving a sports car and change out to a set of winter tires and rims it will not perform the same on dry pavement as much as the summer tires won't do as well on the snow and ice. Alignment is the #2 reason for bad tire wear, improper inflation is #1. You can follow the Goodyear choir or investigate the successes of those who have worked past the ST stigma. It is your money and your choice. I run R250's 1 of which after 20k miles is starting to feather on the edge which means I need to check that bearing and rotate the tires again this year. Nothing I haven't done on my semi over 30 years.
