I run my T32 LWB at 50mm front/rear with 19" wheels, there are a lot of speed bumps where I work and if I'm not very careful I can easily scrape my ABT snow plough.
Annoyingly when my van was converted they didn't check the tyre pressures on my ABT wheels, all 4 wheels only had 30psi in them. This meant that going over speed bumps was grounding me out and it's clonked my nose out of joint, it's gone back today to have it all clipped back in and a couple of scrapes blown over at the same time.
I've been running 55psi since I first noticed they were under-inflated and it's not grounding out as much now. Very annoying and I told the converters they can pick up the tab for the nose job and paint, circa £200ish.
