I don't have bad tires, my khumo tires are holding up just fine but they aren't very good for off road. then again I have a 2wd so i don't really need anything for off road , i got my truck to drive around on the highway and streets. not really knowlegeable of the khumo tires they were on the truck when i got it a year and a half ago but these have held up pretty well and as i said in my post earlier I haul a lot with mine. I have always been a Yokohama and Dunlop fan for the speed rated tires. and BF Goodrich has always served me well for every day street driving that's why i recommended them too.
