I have over 50,000 miles on my MH and never got a flat.
I also purchased a truck tire repair kit for a lot less money just for security.
The kit is designed to patch a hole in the main tire just in case I hit a 3 inch nail. LOL
If I ever got one I can at least plug it then I have time to find another if I really need to buy another tire.
Now if you are not watching your cold tire pressure and your tire is really low and you drive on it will destroy itself because of excessive heat that's another story.
This is what I carry just in case.
