My G-Force Sports have a 550 treadwear rating..
I think the reason why not many know about BFG is because of the pricing. I know enough about the average Falken tire, i see them from time to time at work. and in one simple word, i cant describe them. but one of the better words is cheap. I HATE trying to balance them, especially for trucks, they wear fast and scallop faster then they wear.
I've had the G-Force on for 2 months, they start at 10/32, I'm down to 9/32 and i have 10k on them.
I'm considerably less then a falken fan, But, these are MY opinions. I'm sure other people have had better luck, but on average at my shop, falken tires are considered cheap tires to put on cheap rims.
