Tires from Costco or Sam's

I found that saving a few bucks at the super saver stores not quite worth having to watch over the tech while mounting them, and argue with management if I have a problem.I usually buy tires at a local mom and pop store that has been in business for three generations.They may cost cost a little more but if I have any problem with them later just stop by,problem solved.No written warranty required.They value their customers.The techs working there have been there for years and I have gotten to know them well,they know what they are doing and what I need during service,I trust them completely.I always give them a couple of bucks tip when finished.For me the minor extra cost is worth it.
