Got this felt bmx, rims are slightly warped already , bigger tyres or whole new wheels? I have 9cm clearance from rear axles

I love a Felt. I restored and rode a 24″ Felt racing BMX frame and forks a few years ago.

I think it depends what you mean by *slighty warped*.

They may just need truing. Rims are either buckled and the metal is deformed, or the spokes are unevenly tensioned throwing it off true.

If the latter, just grab a spome wrench and true them up.
