Final answer:
The standard practice is not to repair a puncture less than 16 inches away from another puncture or repair because it can compromise the tire's structural integrity.
Step-by-step explanation:
When dealing with tire puncture repairs, it is generally advised not to repair a puncture that is less than 16 inches away from another repair or puncture. This recommendation is based on safety concerns. Repairs too close to one another can compromise the structural integrity of the tire, which could lead to tire failure. Moreover, repairs made on the shoulder or sidewall of a tire are also not advisable because these areas undergo the most flex and strain under normal driving conditions.
