Hello!

I have a 2014 Trek X-Caliber 4 29er hardtail with Continental Trail King 2.4 on the front and Mountain King 2.2 on the rear. Though they are a huge step up from the Bontragers it came with, both tires are wider and I'm not sure what the correct PSI i should be running them at is. I'm 5' 11", 240 lbs, and it's a 17.5 frame. Being new to riding mountains instead of flatland, I'd hate to take it out with the new tires and too much air and have a blowout halfway down the trail.

Any help would be much appreciated.

Thanks
