I've a full suspension mountain bike with a 26 inch knobby on the front wheel, this knobby has got these rectangular knobs poking out. My problem is that I find my bike's ride "not so smooth". I currently inflatate my front tire to 32 PSI and the rear one, with a better tread and sleeker dimension, to a 34 PSI. The knobbies are particularly buzzy and make this very unlikeable buzz, even on low speeds. Plus my bike's rear hub makes the rear wheel and freewheel wobble, plus the wheels doesn't rotate very smoothly, what should I attribute the bumpy and seemingly harsh ride to? Also, what degree of changes should I make to my inflation levels? My knobby front is new, so changing is really not an option and well, the knobby owes itself to my unknowing self a while back. What I'm looking for is a better riding experience and satisfaction. And, how urgent is the rear hub overhaul, really? I mostly ride on nice paved roads with zero dirt trail encounters (a metropolitan, no far-off excursions)
I have similar treads and vibration on my hardtail. Some solutions:
- Reduce the pressure, but this will increase rolling resistance, thus reducing efficiency. I don't recommend this one. I would prefer to keep the vibration than to reduce my efficiency.
- Just replace the tires to smoother ones. I recommend this one because smoother tires will not only make your ride smoother, but also increase efficiency. You should do this unless you are on a limited budget.
On the road knobby will buzz. If you want less buzz then less knob. You need to get the hub serviced and wheel trued. Why did you buy a knobby if you mostly ride on roads?
Increasing pressure a few PSI may help or it may be worse - you'll need to experiment yourself on this.
You can try wearing your knobs off by riding, but this will leave you with relatively thin carcass and more vulnerable to punctures. And it'll buzz until worn smooth.
I've never tried this, but I have seen someone's effort to make slicks.
However this will drastically reduce your tyre life, and one slip with a grinder will leave you needing a new tyre anyway. Plus it makes a huge mess.
Also, the rubber inside the tyre is softer than the rubber on the surface, so it will wear quicker.
