Spoke wheels anyone? - FLYTYM_imp - 09-06-2018
Got most of parts for my spoke wheel setup now I just need tires. Im looking at a 19-1.85 on the front and a 17-4.5 for the rear. I’m looking at a 110-90 for the front but would like to go as wide as possible on the rear. I can at least go with a 150-70 but would like to get a 160-70 on the rear,can I get a 160-70 on this 17-4.5 rim?

You need to look at the tire specs to find out if that is a recommended width for use with it. What you need to make sure of as well is the clearance on the swingarm for the tire.

Generally speaking, you must use a tire calculator: stock vs modified as a staring point...and if I am correct, % difference must not exceed 3% !!??
Check it out and good luck

Suzuki SV650 rear rims are that size, and they run a 160/60-17. A 160/70-17 should be fine on a 4.50 rim.
I'm curious about your 19" front rim. A 1.85 rim is very narrow - should only take a 90/90 - maybe a 100/90 width, but even then it would pinch it together and make the tire taller and less stable.
Back in the '70s, that was as wide as they had, so people put a 3.50 (about a 110/100 size) on their CB750s and CB500s, which made them handle much heavier.
Newer bikes run a lot wider rims. A Honda Rebel 250 runs a 1.85 rim with a 3.00 tire. A 335-pound Suzuki Savage 650 runs a 100/90 tire on a 2.15 rim. Triumph Bonnevilles run a 100/90 tire on a 2.50 rim. I would highly recommend a 2.50 rim so the tire contour is closer to the rear's.

I’ve been doing some digging trying to determine what size will work,a 19-2-1.5 is what I’m looking at for the front and a 17-4.5 for the rear. I’d like to go with a 17-70-160 for the rear but keep getting conflicting info. Once again thank you,very helpful info.
