Hello guys, want to ask something. My rear tyre last week bocor and i already put cacing. then for sometime no problem then this week i felt that my rear tyre seems like not enough angin then i go check the cacing part bocor again. The pomen said better change new tyre instead of put cacing again at the cacing part as will not tahan

is it true that cacing part if put the same part twice? because i just used this tyre about 1 year for now, the bunga all still good condition
