    why no sealant for car tire?

    why don't car tires use same MTB sealant?

    do sealants work only on small MTB tires?

    I'm going to guess .. because that car tires operate at a higher temperature than bike tires and most (not confirmed) sealant that 'we' use for our bikes is latex based and will dry out faster - I think that the auto stuff is glycol based
    I stand to be corrected..

    I'm no tire expert, but your car tire has much thinker and has steal belts because weight doesn't really matter. That makes it more difficult for objects to penetrate the tire. The bead is also larger to seal.

    This being said my wife's Kia did not come with a spare tire, it did come with a small 12v compressor and a can of sealant to squirt into the tire to get you to the next garage.

    I've used sealant to fix a small nail hole in the outer area of tread that the tire shop didn't want to touch. Worked for 3 years and 40K miles.
    Making shit harder than it needs to be isn't awesome, it's just...harder.

    Most shops won't touch holes in the sidewalls.

    Wasn't Slime invented for car tires first?

    First thing that comes to mind for me is tire balance, but this article has some more reasons to avoid it.

    I know ATVers have been using it for years as it's pretty difficult to carry a spare tire.
