As a noob, this may be a silly question, So I humbly seek advice from those of you who may have the knowledge. I found a nail in my rear tire today. Rode home slowly and just am wondering, should I buy one of those plug kits to repair it? Seems like a failure of the repair job would be ugly!!! I am not independently wealthy, but I have a long ride coming up this weekend. Tire is a tourance with 1500 miles on it.
