Hi there, 
        
 
         I want to go for knobbies at some stage and was thinking about TKC80 but the price is quite high for a pair. 
         
        
 Is there something cheaper (knobbies) what can perform ok on and off the road (but still more off)? 
         
        
 XT660Z 90/90 & 130/80 also seen sowhere that 140/80 will also fit! 
        
 Is it true? (looks better that for sure 
        

 )
