Plug (pasak) then Patch (tapal) on tire?

[dr. d]

If always in doubt, buy a new tire every time mabutasan ka ng gulong para walang multo sa isip.

right!
but for this tyre only.
after all, the tyre is 6 years old na...

but if the guys believe in 6-year tyre lifespans... perhaps replace all four tyres...!

personally,
i don't doubt the tyre.
but the other guys might.

if post-er has doubts,
i suggest he bring it to the official tire brand dealer, and ask their opinion.
if they say it can be safely repaired using ordinary means, so be it. have it repaired then and there.
if they say the tyre is unsafe, then he's already in the right place to purchase a new tyre.
