Smaller in diameter and circumference. AND the speedometer reads off the front wheel on our Valkyries. There was another 130-80-17 for sale in the classifieds but I don't believe it was the one yer talkin about. Should work bit it is smaller than the 150-80-17 that comes on our Phatt Ghurls. I'm going with a 140-80-17 Shinko 777 white wall for my new front tire. IF you do use the new triple 8 let us know how it works out please!

RIDE SAFE.
