I got my last set of Bridgestone OEM tires from BikeBandit, I did not get whitewalls but they carry them.
I was impressed with the selection of tires they have, but you have to put in the size you are looking for and click on each one to see the variations. If you just put in your bike make and model, it will not tell you all the tires they have for your bike.
It kept pointing me to tubeless tires and my bike OEM came with spokes. I found what I wanted there at good prices, but had to search a bit.
my problem is that i cannot find white wall tyres from the same brand in the sizes which work for the 950...and I am scared of mixing front and rear tyres.....so i thought anyone know of a particular tyre brand combination which worked??
