How do you spawn Tires/vehicle parts with the DayZ Survival Hack?

I want to know.

I don't think you can, but just spawn a local chopper

When i spawn helicopters for some reason it only appears client-side and my friends can never ride in it nor see/hear it. It kind of sucks

When it says LOCAL it means it will only appear client sided, except for the backpack, which you can make server sided by changing skins (Civilian,camo,etc).
The survival hack can spawn anything via the custom magazine spawn.
Classnames are here: http://www.mpgh.net/forum/624-dayz-h...mes-legal.html

and last thing, you don't have to repair or refuel a vehicle, there is a option for it in the survival hack itself (option 20).
