tire / tube expert needed

[jphish]

Over last 10 years all my bikes have been tubeless (one of the things I love about my 06' Girly) I'm changing out the battlewings on the 800 for K60's. The rear is a 150-70-17. I could only get a 140-80-17 K60. Only gone about 500 mi. 1) will the stock tube fit & 2) after 500 mi would you change tubes anyway ?  Thanks in advance for any advice. j

1=yes
2=no

Im running a K60 same size as you are using with the standard tube,
why would you want to change a tube after 500 miles??,ive done over 12k miles with mine.
