1977 cb750k tire/wheel/rim help and suggestions

duluth dog
the tires on my old bike are starting to show their age so im looking for a new set.  the tires that were on the bike when i bought it were just standard street tires, but now after i have started my cafe conversions its only fitting i get some vintage looking tires.  i found a good site called cokertire.com that has a good selection.  one of my problems though it that i have no idea what size tires i need to get to fit the rims i have.  i have the originals which i think are 19" but im not positive. anyone have any idea what i should do or suggestions of other places to try?  thanks ahead of time for all the help.

You should have a 17" rear, and a 19" front. If you want vintage looking tires, check out "IRC" they even make them in the inch sizes. However I do not think anyone is making a vintage looking tire in 17". I myself run Dunlop 401s on my bike, and love them.

Front size is 110/90 - 19
rear is 130/90 - 17

You can generally go up or down a size on the rear no problem. Front is tighter so up might be an issue but down a size would be fine, 100/90.

http://www.cokertire.com/motorcycle/tire-rim-diameter/17.html
work? What is thier first number, before the inch size, all about?

I also found these tires through bike bandit,  not exactly what I am looking for but still a good looking tread. What do you think?

I think that's the width. 200=2", 225=2 1/4" inches. The widest 17 they showed was only 2 1/4". The stock 130mm is about 5.1".

That's a good price on those Dunlops. I would jump on them.
