My friend told me that manufactured tennis string is normally 'dead', so we need to restring it, is it true?

teaman, if you mean the string that is in an off the shelf racquet that you buy at the department store or the outlet sporting goods store then yes you should probably have the frame restrung. The suggested tension range is there to give people an idea of how low they can have it strung to gain maximum power while still retaining some control and how high they can have it strung to gain maximum control while still retaining some power. Mid + 2 is a good starting point. Since you don't know where or when the frame was strung you don't know what the real tension is. Hit with it once to see if you can play with it and if it feels like you are hitting long with your normal stroke then the tension is too low. On frames like that the likelihood that the tension is too high is not a consideration at all. Try a nice hybrid or a syn gut 16 or 17 gauge string. The thinner 17 gauge will give you a little more feel and potentially more power since it is more elastic but the 16 will last longer and more than do the job for you.My friend told me that manufactured tennis string is normally 'dead', so we need to restring it, is it true?
It wouldn't necessarily be dead, but the manufactured strings are usually synthetic gut. Synthetic gut breaks a little easier, and is the cheapest string out there. However, the strings aren't deadMy friend told me that manufactured tennis string is normally 'dead', so we need to restring it, is it true?
Yeah. It's all a feel thing. If you use it and it feels fine, there's no reason to spend the money restringing it yet. And the strings on pre-strung racquets aren't always terrible. They are just made to last forever. Also, if the racquet was at the store for a while (or has just sat around anywhere for a while), the strings will have lost some tension.





So, yeah. Try it out and see what they feel like. If they aren't lively anymore, or you just don't like the feel, restring it. And if the thing is more than a year old, put new strings on it. Other than that, just keep using the strings until they either break or don't feel lively anymore.
It is not clear whether you mean (a) racquets already strung at the shop, or (b) any kind of string, since all strings ARE manufactured. If you mean (a) then it depends on how it feels when you test the racquet. While there is no exact rule on how to determine ';dead'; string, you may want to determine how often to restring with this simple rule of thumb: if you play 3 times a week, then you may want to restring 3 times a year (once every 4 months) and so on. The only consideration for restringing is to avoid breaking string while playing tennis. Worn strings are prone to breaking, especially if you hit with spins. I hope this helps.
