I have a 2000 GMC Sierra with the 5.3 and 4x4. Sometimes the ABS and Brake lights come on at the same time and sometimes they don‘t. I had it scanned at AutoZone and no codes showed up. It stops just fine and I can‘t seem to find any issues with the brakes. Anyone know what could be wrong?
What size? There are over 1,700 different tire sizes on the market for passenger cars and light trucks alone. You need to be more specific.

Code readers generally only read check engine light codes, so that's why you have nothing there. As for the problem, I'll start with the obvious. Have you checked your brake fluid level? If that's not the problem then you have to make sure the ABS system is working properly. Best way to tell is to gain a little speed on gravel then slam on your brakes. If the petal tries to push back at you and feels like it's pulsing rapidly, then your ABS system is functioning properly. Move on the the next step. If instead your tires lock up and your truck slides to a stop without resistance in your petal, then you have a fault in your ABS and should consult someone with better knowledge of later model ABS system. So, your fluid level is fine and in good condition (yes, some newer cars and trucks will trip the brake and or ABS light for having old, broken down fluid) and your ABS system is working properly. The last thing I can suggest is bleeding you brakes, including your ABS lines. Air in your brake lines can trip these warning lights and can cause unsatisfactory braking ability. If all these suggestions don't lead to positive results, find an auto shop that advertises free or really cheap mechanical diagnoses (like Meineke or Brake Team) and at least you'll know what the problem is and if it's something you are able to do on your own or have a professional fix.
Yes tehy will provide more grip
