Bought it new and only put 3500km on it so far in 2mths with 1500km of that done in 3 days (towing) so haven't had a chance to wear out the back tyres yet, besides it only gets driven 50-100km in a normal week so i'll have traded it in before it reaches 50,000km.
The VZ SS Crewman has a lower towing capacity than my VE SSZ Ute.
My trailer is rated at 680kg and my car is 560kg so 1240kg all up and usually around 150kg of tools n stuff in the ute tray. You have to look in the rear view mirror and see the car on the trailer to remind yourself that you are actually towing something.
My previous tow car was a 2000 Toyota HiAce 2.4L Auto with 85kw and 200nm (probably 65kw coz it had 350,000km on the clock) that thing struggled just to tow the trailer over speed humps.
