Please advise. I have tyres on my bike that read: 26 x 1.62 K154 that need replacing.

Would it be possible to replace them with 26 x 1.5 tyres since the original size doesn't seem to be available?

With thanks for your time. Anthony.

No problem

Depends on ur rim sizes.

Nope. The difference between 1.62 and 1.5 is minimal. They will work fine.

Thank you. I'm only starting to learn about fixing bikes up.

Thank you so much. I needed the reassurance.

Not that you need my reassurance also, but YES 1.5 tire will fit on your rim!
