To fix white wheel issues, go here:
As for other texturing issues, I've had tons of problems in the past as well because I run 0.4.7. I've learned that most of the time, it's not the game's fault, rather it is the uploader's fault for not making sure every single necessary file is in the zip.
There are two ways on going about fixing this, you can either extract your trucks into the v4 pack, or you can fix the trucks by hand by locating missing files. I personally find it easier to fix the trucks by hand because extracting into the v4 file may mess up and replace existing files needed for different trucks and it's just a mess. I've fixed trucks by hand for a while now and everything seems to still be in order and working for me, although it takes a bit longer to do.
If you want me to teach you how to fix trucks by hand, using the truck file and such, send me a direct message
