I put sealant into the tires

Is it safe for the TPMS sensors?

 

What happens when it dries up in your tires?

 

Cargo cult.

 

This product is kinds cool for M/Cs because, unlike automobiles, motorcycles usually do not have the ability to carry a proper spare.

.....However (comma!) in the US motorcycles are ALSO primarily used as a recreational vehicle and smart cyclists (both motor and pedal) always carry enough kit to plug a leak. Commuters who ride are fairly rare and even those brave souls are selective about distance, routes, weather, hour, etc.
If you live in one of America's vast grey sloburbs then it's possible to get by without a proper spare since there's always roadside assistance - BUT you should also be careful to avoid areas that one would not willingly walk through at night because Mr. Murphy WILL come and visit you and one should not think that a can of "spray and pray" will plug all leaks in a tire.

If you do not live in urban sprawl, then you should consider carrying a proper spare, because time and distance can work against you and once you get out into America's heartland you'll find that there are actually areas where cellular communication isn't 100-percent reliable....and bad things can happen to good people out there too.

Drive without a spare?
I do it all the time.......on a motorcycle.
Wouldn't think of it in a car.

YMMV

 

I haven't gotten a flat in 40 years, and tires are way better today. Nails and screws in tires don't count. Just don't be stupid and pull them out unless you want the tire to go flat on you. Mostly, they cause a slow leak. Have the tire shop deal with it or wait till you get home. Sometimes the screw or nail doesn't penetrate the casing anyway. Pull it out slightly and if you hear air leaking, push it back in. I don't believe in goop in car tires. It isn't needed. Mountain bikes, yes. If in the rare event you get a flat and don't have a spare, you can try the Toyota compressor goop or just call for road assistance. Well, maybe if you are out in the middle of nowhere with no cell service... Not saying a spare isn't a good idea, but there are a multitude of other ways a car can breakdown.

 

Tires can go flat as a pancake with the screw/nail/bolt still in.

But yeah: if it's holding, or partially holding, leave it be as long as possible. Same thing if you're doing plug repair: have EVERYTHING ready to go before you pull the offending object out, and immediately put in the ream tool, and then the plug ASAP. It's easier to push things in when the tire's still got some pressure.

And less exercise later, if you're using something like a bicycle pump to re-air it. Which is possible, a bit of a workout, but not that hard.
