Goodyear (Ds) was what I have always put on my former unit. It is what I will go to when the tires that are on my new unit start going bad (or as long as my nerves can take it). One went bad after 200 miles and the Dealer replaced it and I had no choice in what to replace it with.
A few more dollars may seem to add up, but the peace of mind priceless.
