Coker Firestone Tire Size

[fredintoon]

Jeez Quinn,
you are obviously smart enough to read, eh?
I'll try and dumb it down for you:-
You can't easily find Inch size specified tires no more.
The most popular (there's several) modern tire size system uses millimeter dimensions for the tire section but keeps inch numbers for the tire bead diameter and while the inch-designated tires were all 100% (width equal to section height) a metric designated tire section height is a reduced % shown as xxx/90 for a 90% height, XXX/80 for an 80% and so on.
Front tire:- 90/90 has the same width as a 3.5" but a smaller OD, most everybody uses a 100/90-19, fatter but same OD.
Rear tire:- 100/90-18 has the same width as a 4" but a smaller OD, most everybody uses a 120/90-18 and yes Virginia, seeing as the Special's 130/90-16 fits in the same swingarm the nearest available Metric equivalent to a 4.5" tire will fit.

jeez fredintoon...
you can most definitely find inch sized tires with out issue. There's many online powersports shops that do carry them.

Hi Gene,
maybe you can in Illinois but in Saskatoon? No effin' way. The spotty kid at the bike shop tire counter just mumbles "what's bike is that for? You still got one of those? What's that in metric?"
And it's dodgy buying tires on the net, you can't see if the build date stamp is stale-dated until after it's paid for and delivered.

Maybe buying tires off of ebay is bad, but the larger online retailers know about date codes and keep fresh tires in stock. Rarely do you see old date code tires more so with the vintage style tires as they are made in small bundles.

I've been buying tires of Ebay for years, Never got a tire more than a few months old.
