Wheels

[Larry C Leung]

There is an inheritly LARGE difference between a 7" rim and a 6" rim,
7" is ALREADY below what nearly all tire manufacturers suggest as 
a minimum rim width for a 225mm width tire, and the car manufacturer
has the luxury and responsibility to test the safety of the combination.

Do you really wish to be the test pilot for this application? 

The whole percentage thing is ONLY a guideline, it's not a rule. The
rules are set by the tire manufacturer. Only they truely know the limits
of their tire. In reality, it's really a tire mfg/car mfg combined
effort, 
although reasonable corner weight info may be enough to confirm 
things for the tire mfg alone. 

The only application I've seen allowing 225's on 6" rims is on several
DOT R (race) tires, which have a MUCH narrower range of expected 
uses and conditions from street tires (but being DOT rated, they have
the same liabilities). Tire manufacturers were forced to make this
combination
work due to at least the SCCA's rules for Solo Stock and Showroom Stock
racing. I rather doubt they'd consider this range ideal for the tire.
I've seen
no other application allowing this narrow a rim for this wide a tire. 

I'd also imagine that this is a rather difficult combination for the tire
wrench to seat properly. 

IMHO, it's NOT a good idea, I'd prefer to NOT be driving next to 
a car so equipped.
