Hey all, long time no talk! Been super busy this summer. For starters I know that true winter tires are better than siping non winter tires, I just don't have the money for a new set of winter tires. Anyways, I am running Cooper ST MAXX on my 4runner and had tire rama downtown bozo sipe the center lugs and leave the outer ones alone so that I could get some more traction for winter. With winter coming up I noticed that my siping is not there anymore on my tires due to wear even thought there is a healthy amount of tread left. Is this normal? Can the be re-siped so that I have my winter traction back? This is the first set of tires that I have had siped and it has worked pretty well for not being a true winter tire. Otherwise if anyone has or knows of some 31" to 33" snow tires for a 16" rim on the cheap I would be interested in that as well. I just do not have the ability to purchase a new set of tires for winter but could swing some used ones. *EDIT: I would be interested in used STUDLESS snow tires. I am not much a fan of studs* Thanks for the help guys.
