Wheels - More than 4?

[FRC94]

Hello,
The rules <R06> (below) definitely said we could use as many of the rover wheels as we'd like. Well we've only got the four and I'm interested in more.

Under the additional parts section of the "The Kit of Parts Rev A", section 10.2.4.1 states:
>>> [rule text edited for brevity] <<<

My question, based on the phrasing here, is:
Can we use any wheels we can find, as long as the traction surface is made of the same material, and has the same coefficients of friction? (e.g. could we by bigger diameter wheels, etc?)
Normally, based on the way the rules are phrased elsewhere, I would assume not since the point seems to be, "Use these wheels." But since you did not provide a part number and a vendor, I would not be able to assure that any extra wheels purchased are actually identical to the provided four. This can cause engineering problems but more importantly, I don't want to buy "bad" wheels and get our students DQ'ed.

So the final phrasing of my question is:
(1)Can we use any wheels we can find, as long as the traction surface is made of the same material, and has the same coefficients of friction?
(2)If not, could you please provide a part number and a vendor to purchase more wheels identical to the provide four?
(3)Alternatively, if you cannot provide (2) and the wheels must be identical, can good faith be assumed? "I know they're not identical, they are actually .050" wider/narrower/taller/shorter but that's the closest we could find." Gracious Professionalism and all...


Thank you so much for your time.
