Hey Pluggers,
Sorry i haven't got any pics, but niva rims should fit suzuki. I'm pretty certain that Suzuki, Daihatsu, Lada & Kia all share the fitment. Although offset's mary vary.
I myself am also considering goin to 16's for the same reason, if your running 31's at the mo, 235/85/16 will probably be the closest overall diameter to your 31's.
But the tyre choice is so much better for 16" rims it's really almost a no brainer :-k :-k :-k
