Tires: soothe my troubled mind

Could someone either suggest who to call to find these elusive Agilis tires
(195, 65 R15) or suggest an alternate. I've been poking around for over a
year with no luck.

I ask people at tire stores if they have anything with reinforced sidewalls
and they look at me like I just asked for something that does not exist.
What do people with Range Rovers use? They seem high and heavy. Are Vanagons
really that different?
