We caught what appears to be a Chevy Silverado SS prototype out on a test run in Michigan. This particular Silverado was riding on 275/55R20 Goodyear Eagle LS-2 rubber — identical to the tire size and brand choice found on earlier Silverado SS models. Add to that what appear to be classic Chevy SS five-spoke 20-inch wheels, and this prototype has some important cues that could well point to a more performance-oriented street truck in GM’s new-truck pipeline.
The identical wheel and tire specs could also signal that GM will follow the same jack-of-all-trades approach as the prior Silverado SS, chasing a wide range of performance and comfort achievements without going as extreme as others’ past offerings, like the SVT Lightning or the insane Dodge Ram SRT-10. - See more at: http://www.fullsizechevy.com/news/2014-chevy-silverado-ss-found-testing/
