    I'd like to put a 38/14.50-16.5 SX (or 15/39.5-16.5 TSL's)on a factory 8 bolt 16.5-8.75 rim. It's a K30 D60 front on vehicle, crossover, 50% road/50% offroad use. Anyone see any problems with tire rubbing when cranked or funny tread wear using this combo? No rock climbing in my area.

    Thanks
    Tom

    They would be more likely to have the centers wear out to fast with that combo. I would go with 9.75 wide of you could. Maybe even 12 wide. If your not in rocks then you shouldnt have to worry about keeping a bead. If you do run that rim make sure you dont run high air pressure. Wet a spot in your driveway. Roll over that spot making sure the entire treadwidth is contacting pavement. If it isnt then drop the air pressure until it does.

    The only problem I see with running that combo would be that most OEM wheels have a lot of back spacing which might put the tire into the springs. Tread wear can be adjusted by running the right air pressure to get the correct contact patch. I have 42" TSL's on 8.25" wide rims, but they are 3" back spacing.
