Honestly, the best advice I can offer - especially for a brother who needs to jam econo - is to find a good local indy tire shop and buy a good used matched set from them.
Then stick with them. The guy we go with here in Calgary, I think we've been dealing with him for 30 years. Every ten years or so he moves his shop to try to get away from us, but we keep tracking him down. He's almost always able to take care of us; we've only had to look elsewhere (the local buy+sell - kijiji) for the old '95 Legacy wagon with the small wheels because those sizes are getting rare. Then we still take them to him for mounting+balancing.
