I am going to put a 18'" spoked wheel on a 150 series tire and I was wondering if anybody knew what the lowest profile tire would be for this application. Thanks

I recall seeing a formula on WWW.TIRERACK.COM. Bikes and cars will be the same. What you want to do is get a tire with the same diameter as stock.

which number is the diamater? i believe my tire now is 150/80/16.

160/60/18's look and work great.

i can fit a 160 with no mods? that would be great!

I think all the info you'll need to answer your questions will be found on the website that was previously mentioned. Plus a calculator.

My buddy runs one on his 05 Road Glide with no issues...not sure about softails.

I'm in the process of stuffing a 160x60x18 in my '02 Softail Bobtail fender.

Had to cut 3/8" from the caliper axle tube, (frame side), machined .165" additional clearance from the anti-rotation relief cut in the caliper, added 3/8" longer wheel spacer to the left side, and spaced the sprocket/pulley 3/8" to the left to put it back in line with the trans.

Mock-up looks good. Trick is in the "profile" / 60, and playing with the suspension, (up/down). Also want to turn the fender strut bolts around so the heads are inside the fender to maximize clearance availability.
