Wheel and tyre sizes

[domiles1]

I've just bought a rear wheel and tyre on ebay, advertised as being from a GS750. I didn't look at it closely when I picked it up, but when I got home I realised it was a different size from the one on my bike and the spare I have in the garage. Reading from the tyres, I have:
Tyre on bike: 130/80 - 18
Just bought on Ebay: 130/90 H16
(spare in garage: 120/90 V18)

What I need to know is: could this 16 wheel have ever been on a GS750, were they fitted at any time? Or was it wrongly advertised and useless to me? I bought it mostly for the disc but the mountings are totally different. My hunch is that this wheel is from a totally different bike. Can anyone put me right before I complain to the seller?!!!
Thank you.

The front tire on my 1983 GS750E, is a 16. But not the rear.

Most of the L model bikes came with 16" rear wheels, including the 750L's. It could (most likely) be made to fit your bike. Of course, we don't know what kind of bike you have other than GS750, which branches almost 10 years of production and three different generations.

Thanks, Nessism.
My bike is actually a hard tail chop (I didn't butcher a GS, I bought the chop half finished as a project) and it has GS750 engine, wheels and a few other bits (some bits might be GS1000) and the donor bike was a 1979 as far as I know. The rear wheel is 18 inch.
So I can't really have a go at the ebay seller because its quite possible the 16in wheel could have been GS? Oh well, that'll teach me to check sizes before I buy!

I don't understand the problem. Why not just install the wheel?
