^^^ i think it was in the other thread that i mentioned that those tire repair kits throw the weight off in a tire. even a patch on the inside does it, that why it needs to be rebalanced after its remounted.
any extra weight will throw the balance off. also, since the tires structural integrity has been compromised with the hole, you cant hold the tire to the same expectations such as rated top speed.
but like i said in the other thread, for any regular driving you would be fine with a plug, patch, etc. sorry for the confusion
edit: i just read my second sentence. anytime a tire is remounted it has to be rebalanced. . .
