Alrighty then,
Since everyone is either stumped or uninterested, I'll get on with it.
Here goes...
There is a pattern found in this chart correlating with aspect ratio. As it increases, smaller rims become increasingly compatible with a given width. For example, the smallest rim recommended for a 130/60 is a 3 incher, but a 130/90 can go down to 2.50 inch rims.
Here's why-- at least in my not-engineer opinion
--
Higher aspect ratios give a longer sidewall height, which allows less angle from the rim to the tread, curling the edges of the tread less., thereby giving a better profile and a wider tread compared to the smaller aspect ratio. Remember Dave's tire geometry discussion in the Cafe Tire Thread? Same ideas, but with an additional complication-- aspect ratio. (And yes, Dave, the tires are of different sizes, but the discussion is related.)
In a sense, higher sidewalls are more flexible and can accommodate more rims, while low profile tires are more picky. I bet that low profile car tires are extremely picky about rim size. Their squarish treads can't curl like bike treads, can they?
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1435340395 About ready to drop the money on a couple of shinko 712 rears-- one for myself, and one for my Dad's 750 Shadow. His has a worn Dunlop 140/90 on it. Looking at it, it seems like a lot of rubber for the poor little Savage, but it's mounted on a 3.5 inch rim. Looking to get 'em from Bike Bandit and get free shipping. Are there any better deals out there?

Any particular recommendations on tubes or rim strips?
