The current tires are Front: Nankang 3.00-18 Rear Cheng Shin MS90-16 (4.60-16)

From what I can find online Front 3.00-18 is closest to a 90/90. Is this correct?

I haven't found an MS90 on any of the conversion charts. But going by the 4.60 size I'm thinking 120/90. Is this correct?

What are the actual rim sizes for an 82 XS400SJ? With this I can probably figure out what tires are safe for the rim size, and go from there.

Thanks In Advance!

Anyone?

My Haynes confirms the 120/90, but under the "Wheels" is shows that the info for your model is unavailable. Sorry I don't have more info.

Thanks for the replies guys.

The supplemental from Yamaha does have 120/90 listed for the rear. It doesn't list the rim size for front or rear though.

I believe mine are 18" front and 16"rear, my rims are stock for '82 xs400 heritage special
