I think the OP is looking at Tier 1 tires. Well, maybe not, the answer is blowing in the wind. I don't think Douglas will do though. 
The thing about "longest wear and best ride quality" is that a hard tire wears longer but has potentially lesser ride quality, unless it's aired down maybe. Then the tire edges will wear. Can't win on that one.
Michelin, Continental, Goodyear, Bridgestone etc. are big brand Tier 1 tire makers (apparently) with subsidiaries that make Tier 2 or Tier 3 tires. Douglas is probably a Tier 3 tire but offers good value.
