these are the 900-16 STA superlug 36'ers on the k20.. btw, Coker does not make these and they may not be the cheapest retailer in your area..
while tall/skinny has been difficult to find, some manufacturers have responded to demand..
Interco for one has several newer tire models in both bias and radial in similar profiles.. I have TSLs on the blue k1500 but will likely replace with newer option..
I've posted on this very subject several times, searching my user name and select keywords should lead you to numerous threads..
good luck!
