Best answer: How do you true up a mountain bike wheel?

Can you true a MTB wheel with the tire on?

As long as there are no loose spokes and the wheel is reasonably straight (the rim and tire mustn’t rub on the brake pads), it will ride nicely and hold up fine.

How true should a MTB wheel be?

If your wheel is trued (lateral movement) to within 0.5mm it is considered good. Same 0.5mm tolerance for the roundness of the wheel. Just remember that you may need to take the “stress” out of the wheel as the spokes can wind up with the torque applied to the nipple.

How do you center the front wheel on a mountain bike?

The wheel should be centered between the fork blades. To adjust wheel centering, open the quick release, move the wheel either left or right until the wheel appears centered, then close the quick release. For non-quick release wheels, loosen the axle nuts and center the wheel, then tighten the nuts fully.

Do you need to take the tire off to true a wheel?

If it’s just a minor truing, it’s fine to keep the tires on. If you have single wall rims, deflate the tires first. Sometimes the spoke nipple can twist the tube and pop it.

What can I use if I dont have a spoke wrench?

You can use an unbutchered screwdriver if the spokes do not go all the way through the nipple. If they do, then a screwdriver with a slot cut into it can work. This method works when the spokes are rounded out. But its much better to spend a few bucks on a spoke wrench that fits.

How often should I true my wheels?

Check the spoke tension and wheel truing.

You should have the wheels and spokes trued and tensioned about once a year (if your ride often). Bicycle spoke rings can be plucked just like any other stringed instrument such as a guitar or a harp. Listen to the pitch created by the plucking.

How does a bike wheel become untrue?

In general, the fewer the spokes the more likely the wheel will go untrue. Good training rims are box shaped instead of ‘aero’ and have 28 or more spokes/wheel. You say you ‘have your bike cleaned’. That’s part of the problem.
