It's back....

It was fine for the mile to the station but half a mile from home it started again, this time in the dry.

It's intermittant but somehow sounds like it's related to the turning wheels if that makes sense...

As it happens a while into a ride could it be something heating up with friction?

It sounds more of a rubber squeak than a metal screech but I'm not 100% sure.

HELP!!!!!!!!!!!
