Hmm... no, there are no grooves in those wheels - very clear in picture - I'm not sure where you are seeing grooved wheels unless I'm misunderstanding some sentence syntax above.
However, I have stretched tires over the wheels on Williams diesels which were made after they discontinued magnetraction but before they went with tire traction. It works quite well with clean wheels and just the tiniest drop of CA to hold the tire on.
