Garth04, with the speeds you are hinting at and the size (od) tire your speaking of, suggests to me that your bike is low reving,, maybe do some resurch on what tires the couple of high speed Harleys in the States are using :wink:

Hi Garth04,
The Goodyear 15" LSR range work well on my bike - most of these are moulded to the front runner profile
You need to run fairly high pressures and they do grow up to 2" in diameter at speeds over 200mph
