>>1071402Not sure exactly what you mean by "I can feel the shit eating the metal" but if you mean you feel bumps too much, ride a wider tire and/or lower pressure.
>tube is always inflated accordinglyIf by this you mean to the maximum recommended pressure labeled on the tire, you could try going lower. Don't go so low to get pinch flats obviously, but go a bit lower than the max (if it gives a range, try near the bottom of the range).
If you want new tires, I recommend the Panaracer Pasela PT (make sure to get the PT or TG version, NOT the standard version; standard gets flats too easy). I run the 27" Pasela PTs on my OTS and I love them, best tires I've ever ridden. May also want to consider Specialized Nimbus and Michelin City.
