Does anyone know if there is a website that lists the actual width of tires?

It will be tire time for the project bike soon and I still have no idea what will and what won't clear the belt. I have dropped down to a 5" wide rim and am figuring on a 170 60 17 tire but even the 160 60 17 tires vary over an inch in width.
Any help would be appreciated.

I run 190's on stock rims with no clearance issues. Some mfgrs. have data available:

Why would you have an issue if you dropped to a 5" wide rim you have already lost 1/2" total in width.

by dropping to a 160 or 170 you have already lost approx. 10-20 mm in width across the top, the 60 is the % of the 160/170 in height.

I can't see any issue with any manufacturer where you would be using a 160 or 170 tire. In my opinion

Stirz thanks for the info, most links went to page not found, but a few did work. It would seem that Bridgestone is pretty accurate with their sizing.

Kruizen the issue that you can't see, is the left outer edge of the tire rubbing on the belt. Hence the reduction in both rim and tire width. I will have to mount the rear pulley in closer to compensate for the reduced drive pulley offset on the Ducati motor.

I should have things lined up by this weekend and will be able to take some accurate measurements.

DS 1000 built on deep sump cases. Its the XD-9 project. Air cooled like the XB, but lighter weight and a little more civilized (I hope)

I am currently working on adapting the rim to fit the 30mm axle. I will post a picture once I have at least one side done.
