The answer to the question is simple. No you should not accept the aircraft.
If you are not satisfied with the tyre wear, have it measured against the Maintenance Manual limits, if it is outside limits the aircraft is unserviceable.
If the fuel gauge is unserviceable, check that there is an acceptable deferred defect enterred in the technical log and that the aircraft Minimum Equipment List permits the type of flying you intend to do. If there is no entry or the MEL does not allow your type of flight, don't fly.
