I installed a set of 255/55/18 General Grabber HTS tires after reading all the glowing reviews on-line. Couldn't be more impressed. I drove out of the tire shop and into 10cm of fresh snow last weekend and they are performing very well on snow and ice.

I've had them up to highway speed and don't notice any balance issues as per the previous post (I was only able to locate one single on-line review that mentioned balance issues, so don't avoid these tires on that account).

People may poo-poo these tires because they don't carry a higher profile brand label but, so far, they are great in this Canadian winter (or as good as an all-season tire can be).
