How does car work, and how to replace wheels

[Mrvictory711]

Hi!
I’ve been trying to make a vehicle in Roblox. I have a mesh, and thought I would use the car below as a base. However, I noticed the wheels are not welded or mentioned in any scripts, and simply touching the chassis. If I move the chassis or wheels at all, the whole thing falls about. How are the wheels connected to this?? I wanted to replace the wheels with really big ones, but am unable to. Could someone explain how the wheels are connected, and/or how I could connect the big wheels please?

In Studio, go to the Model tab, then the Constraints sub-tab, and turn on Show Welds and Constraint Details.

I did, nothing shows. There is a transparent block called “thruster” with cancollide off and transparency 1, which is on the wheel. But if I even touch the movement arrow on it the wheel falls, if I touch the movement arrow on the wheel it falls, so somehow it’s just on

The wheels are welded to those thrusters and the thrusters are welded to the chassis. If you want to change the wheels then update those welds (found in each respective “thruster”)
