never had sidewall issues with EXO maxxis in the peak district, ride it all the time and down every rocky descent going, always the sidewalls have been totally solid for me
ive ripped a few knobs/punctures on the beast etc on sub 800 gram rear tyres but anything over 850 (high roller 2 etc) ive never had an issue
I’m not heavy mind at 11 stone ish, also depends on your style of riding etc
infact ive had 3 punctures in 3 years in the peak disctrict, all of which were on light sub 800 gram tyres, first 2 punctures repaired on the trail, and the last one I had I tore a knob off more or less down lockerbrook so tubed it and wrote the tyre off
I’m currently on minion DHR2 rear WT 2.4 at 900 grams (still rolls great) and have just bought a 2.5 WT shorty for up front duties once it gets sloppy
