My build took me in the direction of larger tires, so I'm selling my 285's. I'd estimate 5K miles put on these. Wheeled on them once. Lot's of tread left, see pics (sorry if one is sideways). I can try to get a tread measurement if needed, but pics should give you the scale. Spare is well used, but it's the spare. One tire does have a patch, due to a nail. No sidewall issues. Would like to get $500 for the set. I can send more pics and info if needed. SF Bay area.
