Replacing Tubes

its time to replace my tyres, and after around 2500 miles, should i change my inner tubes too!?

theres nothing wrong with the tubes, but surely they must face some harsh abuse!!!

thanks

 

Are you made of money!!??

 

Of course you should replace your inner tubes. You'll know when it is necessary to do so when they are too badly punctured to repair.

Any other time? No.
