No.
I have the rubber tips.
They are not silent, even though they're called Silent Tips.
The purpose is not to mute the sound of the drum when you hit it with the stick - if you think about it, it does not make sense at all, because in that case why do they make a sound when you use rubber mallets on drums and cymbals?
Rather, the purpose of the silent tips is to allow you to practice anywhere without needing to have a practice pad. The idea is that the tips will mute the attack of a drumstick against a hard surface, eg against a table top, so you can practice on a table top without a practice pad.
They work for this purpose, but it isn't practical - it won't be long before someone complains about the table ringing or vibrating.
What is useful, is that as a side effect, you can get something close to the sound of a rubber mallet by using the silent tips. It cuts out a lot of the attack on cymbal rolls and on mallet instruments.
I bought them from Swee Lee, not sure if they still sell them, but they were cheap - about $4. They didn't fit over every tip, though - I had to cut a bit in order to get them to fit over my VF 3As.
