Been driving KO2s for YEARS since they came out. Put a set on son's truck 4 years ago. LR E was the only option in that size. Not high mileage, and the tread started peeling back from the sidewalls on the two front tires (rotated regularly). Discount did full warranty, but went with Goodyears for a load range C for the 2wd that rarely tows a trailer. First time I've EVER had an issue with KOs
Soon after buying my 2020 Tacoma TRD OR, I put the 4runner SEMA wheels on it to specifically be able to put on BFG KO2s, LR C to avoid the MPG drop notorious with LR E's (only option on stock wheels). On second set, no issues with balancing/treads, etc.
Have heard some issue with balancing on these tires with KO3s and that is somewhat worrisome, since I will need new tires in a year.
"Green" is the new RED.
