Hi all,

I have decided on Shinko 712 tires for my '72 Cb750 K2 re-build. Seem to be the best quality on a budget and considering I don't have a whole heap of time left to ride this season I don't want to go crazy with price.

Here is the link to them: http://www.bikebandit.com/tires-tube...tire?b=1633938

Original specs for front tire are 3.25-19, Rear 4-18. Looking around here and other sites that translates to 100/90-19 and 110/90-18 respectively, correct?

Then with my rims being spoked I'll need tubes but this is where I'm not 100 percent that I've got compatible parts. These are the tubes I'm looking at:


There is an option 100/90-19 for fronts and then 4-18 for rear. These should fit, right??

Thanks so much for any help
