"What do you think, should I give them a try?"
Look at these web sites first.

I think the all steel ply Sailun would be a better choice if you do not want to pay the high price of the GY G614.
Note this is the same chinese company that makes or imports the Power King TowMax(BlowMax) tire.
At 169 bucks for a LRG 16" LT - it just has to be a great tire, right? And the guy down at the local tire store said we have had really good luck with these, right? Then he said "see you soon!"
