Guy's you are confusing things here; following are the manufacturer recommendations for best drive, fuel economy and vehicle handling with regards to tyres selection for Toyota Passo:
For 13" rim size, the rim width should be 4.5" and offset of +35. The tyres installed should be 155/80 R13.
For 14" rim size, the rim width should be 5" and offset of +40. The tyres installed should be 165/70 R14.
These are for Passo 2010 KGC 30. I can provide you guy's with all details for a specific model apart from this if requested.
