yep, yep, i know all of you are with a beer in the garden
but i investigated the noise coming from the rear of my Forester as it was only 23 degrade according the outside temp gauge.
first i swapped the spare tire with the rear left side and took her for a test drive, noise still there, bugger.
then i swapped the right side and test drove her, bingo noise gone! :)
checked this tire and i could see a small bubble and lots of small cracks so no wonder... this Geolandar G900 is from 2011
the spare tire is from 2006 (probably same age as the car) and is in good shape so now i'm off to source two new tires as the other rear tire is also from 2011. both fronts are from 2013.
happy with an easy fix B)
