I can share my 5 cents( inflation ) on the air presure,my 7.3 has the same tires as your,110 lbs at max, my suggestion is base on what i found on varies websites,your ground which your bike rides on and your body weight determind how much air is at the ball park,take it into consideration, smooth surface is better suitable for higher presure and vice verser,if you are not a heavy person,say 180 lbs start off with 90 lbs at the rear and minus 10% for the front,which will be 81 lbs,like i mentioned, the bottom line is about comfort or speed,you need to know what you want first.Thanks for reading.
