What's the difference between these two wheels<img src="emoticons/icon_smile_shy.gif" alt="Shy"> Is one easier than the other to change a tire on and why? How can you tell the two apart<img src="emoticons/icon_smile_question.gif" alt="Question">

Combat wheels have bolts all the way around holding the two halves together, much like the HMMWV wheel that way you can disassemble them in a front line environment with simple hand tools and replace the tire.
