How can you tell if a Douglas rim is .125 .160 or .190?

I just bought Razr's on Douglas .190 rims...at least I think there're .190"'s but I'm not certain. It says so on the invoice but the rim isn't stamped anywhere that I can find.
I also noticed a slight whobble in the wheel, up and down, not in and out, about a quarter inch or so. The quad's a brand new '02 400EX with about 10 hours on it so I know its not the bearings
is this to be expected with brand new Douglas .190 (I think) rims?

What color douglas stickers are on it???? IF there red then you got red labels which are .190's....

You mean the only thing that tells you the .190" thickness of the rim are these red labels that I tore off? My first impression of Douglas rims is not the greatest, why not stamp the number on them and champher the rim for the lug nuts, I turned the nuts around so the flat side is against the rim... duh.
Other than having a spare set of tires, I should have put the Razr's on the stock rims.
