Can I get a wheel diameter in mm - Revell tuners?

Hello. 
Can someone provide me with the diameter of a 1/25 Revell tuner wheel? I think all the tuner kits use the same tires, but if you have a Focus SVT, that would be ideal. In millimeters please. Thanks!

Nobody’s got one?  OK.

I have a Focus Matt. I'll dig it out and measure one for you.
