Fix my wheels

A prob popped up with my wheel spawner. The wheels always weld to the tread and spin on the wrong axis. how do i fix ?

You can press E to change what Axis they spin on. What do you mean by, “Weld to the tread”?

Unfortunately the E key doesnt seem to change the rotation for me either.

What i mean by welding the tread, the tire welds sideways. instead of welding like -O—O- i get -|—|-

EDIT:
OK… oddly enough it seems to have fixed itself when i changed tires this time.
And the E key does work for me, found i have to be closer to the tire than i was before.
Is there any way to get smaller tires ?

Try the phx 3 SVN. It adds a bunch of wheels.
