Cannondale Siemens Mobile MTB

Okay gentlemen, what are our tyre options for this bad boy? The one's that are one it are a bit tired, mostly visually I have to say but...this is the bike for the Mrs you know...
Requirements:

• 26 inch
  
• 2.15-2.30 wide
  
• skinwall highly desirable
  
• current setup it tubeless but I don't mind going tubs again whatsoever
  
• the bike will be seeing mostly hard surfaces, tarmac maybe an odd forest trail.
  
  
  

I was looking at schwalbe table tops (which seem to meet criteria) but the reviews seem to mention extremely weak sidewall (not an issue I guess) and almost no grip on any loose surface (which kind of makes sense but NO grip, really?)

Thanks
