Chopper tire selection suggestions? Pictures?

So I am finishing up a rigid xs build. Bike has the 19/18" alloy spoked wheels. I am having trouble visualizing what size tires to run on it. It is also holding up the final placement of my rear fender.
Tires now are 100/90-19 and 110/90-18

Bike is nothing special, run of the mill build. Things are mostly mocked up in this photo.

I like the look of this tire/wheel combo. What sizes do you think they are?

A 5.00-16 on the rear and a 90-90/19 or a 100-90/19 up front.
On your 18 inch rear you might get a 120 wide tire to fit with out the chain hitting the tire.

that rear is a goodyear that has been discontinued, but shinko makes one in 16" that is pretty close. The front looks like an avon speedmaster. I run the same combo, here's a pic.

I'm running a Kenda 2.75-19 on the front of my bike. It is skinny, no wider than the rim. Looks a lot like the popular Speedmaster tire but didn't cost $150. I've got a 120/90-18 on the back, no issues with the chain.

What size tire is that in the front?

I guess shinko doesnt make a tire like your rear in 18"

Also where is a good place to shop for them?

the front is a 21x3", but they make them in a 19" also.
I buy the shinko from motorcycle superstore through amazon for 85 shipped, and the speedmaster from tires unlimited but it seems they went out of business.
bridgestone also makes a 19 ribbed front that came stock on kawi w650's called the accolade, but isnt cheap either.

Im liking the look of this "Avon Rear SM Mark II 4.00S-18 Blackwall Tire - 1646801"
https://www.denniskirk.com/avon/rear-sm-mark-ii-4-00s-18-blackwall-tire.p641004.prd/641004.sku

What does 4.00 translate as far as 110/90 120/90

Also like the Avon Front Speedmaster Rib 3.50S-19 Blackwall Tire - 1657601
What does a 3.5 vs a 3.25 tire look like on a factory yamaha 19" wheel... or compared to a 100/90

 

[jd750ace]

A 4.00 is the equivalent to a 110.

3.25 to 3.5 is the equivalent of an MM90 or a 100/90

Also bear in mind that "S" rated tires are only good to 112 MPH, if that makes any difference.

 

[PatDoody]

Thanks. I doubt my xs will ever go 112.

I found these sites they are good references.

I use the 2012 MSF tire guide PDF because I downloaded it and I can reference it faster.
