Are my tires still good..??
I have a set or 285 kumho ectsa mx's in my rear and they are approx 3 yrs old and still have about 80 % tread left over cause this car is NOT daily driven. there is a rumor going around that the tires go bad over time regardless if they are used or not...how true is this..?? I havent noticed any difference in traction over the yrs other than when i crank up the boost... which is obvious, more boost = more power. Are my tires getting old to where i just need a fresh new set..??

If the car has sat in the same place too long, it can cause issues. But after some driving, they get back to round.
The main thing is the environment they have been stored in. UV rays and o2 both cause issues with rubber. I bag my race tires over the winter to minimize it. I have no idea if it makes any difference or not, but I feel better about it.
I would say, as long as you don't have any bubbles in the side walls or dry rot, I wouldn't worry too much about it.
As far as the tire not having any grip left, well, they probably don't have as much as they once did, and most, if not all of the new tires in the same category as the MX's are WAY faster than that tire. So a New set of tires will have better grip. But if you are still having fun on them, who cares. If they are hard as rocks, and you want some new tires, go burn em' off and get a new set of stickies.

There are a crap ton of UHP tires either out, or coming out.
Check here for a couple of the new ones.http://sccaforums.com/forums/thread/330994.aspx
Bridgstone is replacing their reo1r with the re11r, and there is also the Dunlop drizza star-spec, Kuhmo has released their XS (finally). The Falken 615 is now considered a "slow" tire. At least in the street touring autox world. YMMV
