Trying to decide on what classic looking tire would fit my bike better (1978 XS400E)....
But its kinda confusing cause i see different sizes...
So i see in my Haynes/Clymer manuals different sizes:
Haynes:
front: 3.5in x 18in
Back: 3.5in x 18in
Clymer:
front: 3.25in x 18in
back: 3.5in x 18in
I think I've read on the forums here the older XS400's had 3.5x18's on both. So i trust that...
The wheelmags has this listed on the metal which Im guessing maybe this is the 'Section Width' that Coker store mentions?:
front: 1.85? x 18in
back: 2.15? x 18in
anddddd my current tires say on them in terms of the 'standard measurements' (example: 100/90 x 18) which i think is tire-tread-width/percentage-of-that-is-tire-height x overall inner diameter?:
front: 100mm/90% x 18in which to me equals... 3.94in(3.54in) x 18in
back: 110mm/90% x 18in which to me equals... 4.33in(3.9in) x 18in
Im guessing these are larger than stock? They seem fine to me riding though.
Just curious what I should get between the choices without running into clearance issues which I heard can happen. Here are my choices:
Coker Classic Diamond Tread Blackwall - 400-18
Cross section: 3.90"
Overall Diameter: 25.75
Recommended Rim Width: 2.15
Coker Classic Diamond Tread Clincher - 385x18
Cross section: 3.40"
Overall Diameter: 25.30
Recommended Rim Width: 1.85 - 2.00
Firestone Deluxe Champion Blackwall - 400-18
Section Width: 4.25
Overall Diameter: 26.57
Recommended Rim Width: 2.15
Firestone Deluxe Champion Blackwall - 350-18
Cross section: 4.05"
Overall Diameter: 26.44
Recommended Rim Width: 1.85 - 2.00
Thanks for any advice ,
