let me see.... what you paid for the liteskins is a deal even at 80 bucks for the pair .... they are significantly more than the regular ones... I believ you about the size ... we have only gotten 20 x 2.15 in so far and Schwalbe hasnt said anything .... buh ..lol

you might want to start a little different approach ... dont start low and go back and forth .. start with high pressure and slowly go down. You might find that even at significant more pressure than you think they will be much more comfortable than a smaller tire with even less air pressure.... added bonus is that they will not feel sluggish and slow ....
