Be VERY sure about the correct bead angle, and any other specs you must have, before you order. These peddlers make a living out of being less than straight with buyers they think they may lose a sale from.
The size, manner of supplier gently evading specifics, lack of sample, country of manufacture, and tyre dimensions all sound INCREDIBLY CLOSE to the way my friends transaction went.
We have consumer laws in first world countries, India and the like, do not.
My friend is still selling from his batch of tyres, 9.0 x 16" that will fit Land Rovers, 25pdr and the like, but won't fit CMPs (according to 'professional' fitters). Those tyres are already here in Australia, and cost well under the guesstimated $300AUD mark. They come with liners and tubes.
Foot Note: The tyres have actually been fit to CMP rims, but there is a trick to it apparently.
