Depending on what part of the USA you live in, try out a Discount Tire, also known as America's Tire in some parts. They will either reset them for free, or for a very low charge. When I took off my winter tires (on rims) last April, I went to my local Discount Tire and in a matter of minutes, at no charge, I was rolling correctly again. They are my go-to source for any tire related issues here in Michigan.
