I got my second nail in my terra grapplers today... this time the f-er was just a dull round flank of metal (like a broken screwdriver but thinner and flat ended). So I am beginning to think that the TG's are very soft.
Since I had to get my tire plugged when they removed it how long do those plugs last for? Is it ok to offroad with a plugged tire? I am quite depressed about it... the first screw was so small that it didn't puncture the tire so they just pulled it out.
