Looking for sifu advise for tyre and inner-tube replacement due to benjol on my Dahon 20" foldie. Currently I think is 406 20" x 1.35 tyre.

1) Can I replace with 406 20" 1.5 or 1.75 tyres ? Will it fit into existing rim ?

2) If I get 1.5, for the inner tube should I get 20x1.25-1.5 or 20x1.5-1.75 ? What is the impact, pros and cons ?

Thanks

I understand the luggage maybe is for flight travel to a destination. But if take into LRT/MRT, once reach the destination station and pull out the foldie to cycle to work/office, where to keep or hang the luggage ?

I am still using the Ikea Dimpa bag, as it is foldable.
