Depends. If you are using resizable wheels as wheels on landing gear, they honestly are a pain to nake work, so I'd just switch to using the very basic landing gear as wheels. If it's using the normal landing gear, you might want to mirror the planes, since something on either side may be causing uneven drag, and mirroring will solve that.

Might be a traction issue. Try adding more traction to the main wheels.
