My rear tire is starting to square off a bit (though there's no abrupt transition from straight line to leaning - yet). There's probably a millimeter left before the wear bar is even with the surface of the tire, so I figure I've got a little time left . . . right?
I don't recommend judging a tire by the profile only. I just got a new tire which looked great, lots of profile, but I noticed that it was made in 2012. Tires still have about 5% of natural rubber in them and they dry out. If you can see cracks in the side wall you should have changed it already!
I'm not saying that your tire is old, it probably is not because your bike isn't that old, but thinking that since there is a millimeter left it's okay to ride may turn out to be a mistake.
I've also learned - the hard way - that an almost bald tire picks up nails more often than a new one.
Edit: I stick with Pirelli Diablo Rosso - pun intended!
Edit again: why are you looking for "not expensive" tires? Tires are what connects you to the road and can change the entire riding experience. My CRF250M was okay to ride with the stock IRC, was more fun with Michelin Pilot Radials which lasted forever, but the real fun started after I spooned on the Pirellis.
Before I spend money on adjustable levers, better fork internals, slip-ons or even bling I try to get the best tires I can get for the lowest price.
