It helps out tremendeously to air down. Ride quality, traction, and less punctured tires to name a few benefits. For a year or so I was using a portable Harbor Freight compressor which was a knock off of a Viair Portable. It was slowly dieing so I decided to drop some coin and got an actual Viair compressor and it kicks butt and airs up my 35's fast!!
hm.... tempting. i know once snow season comes around imma have to...are you running the viair AND a tank? or just the compressor.
Yeah they did well plus airing down helps a ton! I tore them up nicely in a few spots! I somehow managed to take a 3" strip of rubber off that was about 1/4" in width and 1/4" in depth on the edge of the tread on a rear tire. Lockers is what really helped the most!
