i used to work at the ben tire warehouse in indiana, every 1 out of 4 thornbirds we sold one came back because of defect, usually a torn off lug, driving them on pavement tears them up fast, about 1 out of 10 tsl came back for the same reason, but i hardly ever seen a bogger come back, man i used to unload semi's full of boggers, irocs, swampers, I wanted a set so bad i wanted to sneek a set out to my truck,lol
