anybody???

 

I'm no expert and can not provide a definitive answer, but I did learn a little recently when shopping for wheels myself. This might help:

The Victor Equipment website does not show 20x11 in their fitment options for the 955...

However, you can get some useful statistics that will compare the fitment of two different wheel packages here...

If you happen to be on 18s, here are the factory 20in SportTechno numbers (assuming typical tire selection)

275x40x20x9x43 (with 17mm factory spacer, 60 ET without)
or
295x40x20x10x55 (although I seem to recall a post here or on 6speed of somebody running a 315 on this rim in the back, probably in a 35 series sidewall)

Have you tried contacting Victor Equipment directly?
