Tires for RD400C

[Membername]

I know they are front 3.25 x 18 and rear 3.50 x 18 but what does this mean in the metric sizes?  What are the best sizes for the RD400C?

Thanks,

I believe a 90/90 front and a 110/80 rear is the best combination for the RD.  350 or 400, street or track.

Thanks Lyn.  I'm thinking Bt-45's or Avon AM26 Roadriders.

Can't go wrong with those.
It's all about preference and opinion.
