Ride-On sealant stays completely down in the tire tread area. No residual is flung onto the wheel. When I had my Ride-On equipped Vredestein tires swapped from my OEM wheels > PPA wheels, the liquid remained completely in the tires. No need to replace after a wheel swap 
		 
		
	 
And that's exactly why I said '
Some' are 'less messy'... & 'the tire balancing stuff is 
likely....' 

  cos while 
SOMETIMES, you might be lucky enough to get away with it - at other times, &/or possibly with a slightly different product or set of circumstances, you just 
might not be quite so lucky as to get away with it!! :shocked:  
So I'll say it again, 
Be Warned, while 
SOME of this sorta stuff might not be too bad, or 
SOMETIMES you might get away with it/just happen to luck out; but since 
any of this sorta stuff 
CAN be quite messy at different times &/or under different circumstances during the tire remove/refit process, and if it is, you really 
won't be appreciated by the tech doing the job and 
may very well end up on the receiving end of those rude words &/or extra costs!  :lecturef_smilie:
You may also find that just having been sprung 
ONCE at some time in the past with the mess caused by some of this stuff (possibly even a different brand/type 

 ) is 
more than enough for a particular tire tech &/or the tire outlet, so they may well refuse completely to even 
consider working on your wheel if they know the tire has 
ANY type of flat tire prevention agent &/or freely moving internal balancing agent inside it - as is their right! 

 Which is why 
anyone considering installing this type of agent needs to be aware that once installed, they 
just might find it difficult to get anyone to remove & refit their tire/s! Hence the warning! Caveat Emptor! :thumbup:
