I run the M/T 9x29.5 "stickshift" slicks, tubeless, and they lose about 1 lb a week, on the initial installation. I also run M/T`s tubeless on my low 10 second 4 speed bracket car (14x32`s), and they also normally hold air quite well, but the pair on the car currently lose air very fast, like 5-6 lbs overnight! However, these tires were bought used from a friend, who said they held air OK, but now they are leakers. Maybe mounting and dismounting them a couple of times makes them "unhappy". I hate running tubes, especially in the large slicks, cause the proper natural rubber tubes are very heavy. The M/T tubes I have in the garage are almost 12 lbs each!
