Need a strong 2.4 tire

Keep getting pinch flats maybe its because i run less than 30 psi but if you run more you don't have any traction? Have tried differant brands of tubes, still keep getting flats and tried downhill tubes which are way to heavy. Don't think i am interested in going the tubeless route, what a mess that is. Looking for a good xc or dh tire that has a strong sidewall so i can run low air pressure that can handle the rocks. What tire do you recommend, don't care how heavy it is.
