I just found out I have been over-inflating my tires on the MoHo by 20-35 pounds since I took ownership in '03! The previous owner told me to inflate to 80-85 pounds, and that's what I've always done. While preparing for this trip I found a little slip of cardstock hidden in the collection of paperwork previous owners had stored. This label that used to be on the driver's door shows the weights and inflation values the manufacturer recommends: 50lbs rear and 60lbs front! Are you kidding?! That might explain why the ride is so rough and why I've had chronic blowouts! Ok, I'm sure the ride will still be rough, but still! Speaking of blowouts, I have gone through a heck of a lot of tires in those 5 years and not one of the shops that replaced them has suggested that this might be too much pressure for my load! Ugh! Now I just hope the tire sizes are right. I have a sneaking suspicion that the tires are not mfg spec but a taller profile that when inflated to 50psi the dually's will rub (a problem I've had in the past). Anyway, that's my rant for the day... and a cautionary tale for those who haven't confirmed their mfg specs!
