For an International manafacturer Goodyear could definately improve some of there model lines.
On the Eagle GA remarks...no matter how hard i drove them (S & T rated sizes) they perfectly last until 45,000 (well they were below 2/32nd by then)
However i had them rotated religiously every 6,000miles and rebalance every 12,000k. The only thing I should have done was had them re-aligned every 15 or so to cut back on Toe wear out.
For comfort great tire, they did skimp on compound due to it rather fast weathering. Sidewall did scream on cornering but for a luxury touring tire what do you expect?
Lines like the Weatherhandler LS-Sears/Viva Touring/Regatta 2 are clearly excellent tires for the price range and market.
Dunlop Sport SPA2, owned by Goodyear is also a great H rated A/S tire. While I am not exactly clear on the official GY-DN relationship I know to order DN's you go through GY cust. service.
Goodyear relies on its high performance racing sponsors for its credit (nascar, indy etc)
They do like others have said make great Ultra High Performance lines (F1 Family etc)
Michelin has weakness too...there MXM4, V4's, XGT's, Pilot A/S all have a sidewall bubble prone contruction too.
Its uncanny common on Michelins...still an excellent tire not without some problems.
So, before you rite off GY please be more specific.
Personally I would be tickled right now if i could test drive a GY F1-GSD3 German made UHP radial...or a Michelin Pilot Sport A/S or Pirelli P-Nero Tire.
Depends on the company and product.
