So Im putting winters on this car im selling and I just got to the passenger front wheel and one of the lugs is so worn its not a hexagon anymore, its just round and worn. This is a 2016 toyota corolla with 20k on the clock, I suspect since my uncle was the last one to change and he does his mid 80s cars at the same time that he ended up stripping the lug or using one of his old lugs on her car. Should I just put the winters on the rear wheels or just keep all seasons on. They were planning on driving to Edmonton today.
