If a pair of tires(Dunlop Sportmax Qualifiers) are going on 4 years old, but don't have much mileage on them, are they still okay to trust? The tread depth passed inspection but the front does have some small cracks in the grooves. The bike I bought w/only 650 miles still had the stock tires but I've put about 2000 more miles on them and they seem okay. They hold their air pressure and handle really well. The age is what worries me the most. The type of riding I do can best be described as pretty intense street riding whereby I'm pushing the bike pretty hard through the curvy state forest roads, and hitting off-ramps on the highway with considerable speed. Occasionally I may exceed 130mph on the highway, for very brief periods.

Your post is kind of confusing. Are you saying that the Dunlop Sportmax Qualifiers were the stock fitment tire, and that you've put about 2000 miles on them already? If they're working fine for you right now, they should be OK for their expected lifespan (meaning you'll probably replace them sometime this year). Note that the OEM fitment Dunlop Sportmax Qualifiers have different construction, profiles, and compounds than the ones you can buy off the shelf.

Sorry for the confusion. I bought the bike 3 months ago used, and it has the OEM Dunlops on it. The bike is an 06', so that would make the tires close to 4 years old.

If the tires don't have any major weathering cracks in the tread or sidewall, they should be OK, especially if they've worked for you so far.

Okay, thanks Kento. I'll probably replace them w/the new Pilot Pure Michelins for next year anyway, but for the meantime it was just in the back of my mind that the stockers were getting pretty old. So... as far as the different dimensions of tires goes... is that something that I should compensate for with the setup of the bike? I can't imagine that the different dimensions between the new tires and the OEM tires will be that noticeable, or will it?

It's hard to say (even though I assume you're getting the same sizes as stock), because you need the measurements of the tires mounted in order to get a realistic comparison of tire height; despite the tire size numbers being the same, one company's 180/55ZR-17 is not the exact same dimensions as another's 180/55ZR-17. The only thing you can do is see how you feel when you ride on the new tires, and attempt to compensate with suspension adjustments from there.
