I believe that the Yoks perform better than the Conti's.

I also think the rim design on the HRE's is a bit different than on the Techarts and that impacts the overall appearance (to me anyway).

 

Doug, I noticed on my 540R's which were 11" had the stretched look, but on my new 843's the rim bead isn't as exposed as the 540R's. Not sure if it's the wheel or tires, the wheel bead seems to looks the same, so it could be the Yoks could have made some changes.

 

Duane - I think you should get Tirerack's extended warranty/road hazard protection program
