My observations say yes, lower air pressures allow for more tire/tube squirm and potential abrasion. Just look at tires that have been ridden w/ too little pressure and see the cocked over valve as the tire tries to move rotationally on the rim and the tube valve is trapped in the valve hole. When one takes a low pressure ridden tire there will often be abrasion scuff marks on the tube sides with rubber dust collecting inside the tire. Andy
