I have installed and had one landing with the new Desser 11/400-5 tires.  With that experience I can say that they seem very sturdy and yield a nice ride.

 

Two observations:

 

1. The tires were delivered with new tubes made in Indonesia (and with complimentary tire talc).  They seemed alright but the stems are just a bit off  and sit at a slight angle thru the Matco hubs. 

 

2. My left old Chin tire surprised me.  Worn so that no treads were visible in the middle two-thirds of the tire, I noticed that the remaining area was paper thin.  Gulp! 

 

Grayhawk

Another reason to be gray.

 

PS Today I requested a replacement Airman's Certificate stamped with "Proficient in English" in order to comply with the ICAO regs.  It is the only Government form I know that is not also published in, uh, another language.
