If you change the 04 nothing much seems to happen on its own? Thats what happens to me.
I think its to do with other variables as well.
In the picture provided in the OP I also changed the 0A 08 so mine looked the same, A few bytes after and when you go to the GT Auto and do a car wash or oil changed you then get the tyres which have done something? Just look in your garage at it afterwards.
It appears they have grown but also they are no longer in the wheel wells. (Stretch the chassis)
LMAO.. this reminds me of the insurance commercial on tv about everything on the internet being tru.
I just ended up putting the values back to what they were originally.
