21" tires
On the 21" wheels, stocktire sizes are 255/40/21" and 285/35/21". The only Michelin Pilot Sport 4S sizes available are 265/40/21" and 295/35/21". Has anyone successfully jumped up in wdith with no issues? The wheels are 8.5" and 9.5", yet the tires indicate a minimum of 9" and 10".
The stock Continental fronts wore at 8K miles and would not buy them again.

I haven't, but have looked at using those widths for snow tires (20" rims though)
My concern would be if the tires will rub on the front control arm. I can barely get my pinky in there between the tire/rim and arm.
If I go that route I'll probably go with spacers anyhow.
As for the minimum rim width, it shouldn't be a problem, below is from the tire rack website.
"Additionally, some vehicle manufacturers have developed Original Equipment applications in which the rim widths are not within the tire's original approved rim width range. For example:
1995 BMW M3 combined 235/40R17 sized tires on 17x7.5" rims (which are 0.5" less than the narrowest 8.0" wide rim listed for the size).
Corvette C3 models combined P225/70R15 sized tires on 15x8" rims (which are 0.5" wider than the 7.5" wide rim now listed for the size).
Corvette C4 models combined P255/50R16 sized tires on optional 16x9.5" rims (which are 0.5" wider than the 9.0" wide rim now listed for the size).
The rear tire application for Porsche 911 GT3 cars during 2010 - 2012 model years combined 305/30R19 sized rear tires on 19x12" rims (which are 0.5" wider than the 11.5" wide rim listed for the size).
