Wheel rotation explained: 900°, 1080°, soft lock and steering ratio

What the rotation setting of a racing wheel really does, why the driver and the game both have a say, and how to set it up so the wheel on screen matches the one in your hands.

“Rotation” is the total angle the wheel turns from full left to full right, also called lock to lock. A 900° wheel turns 450° to each side, which is two and a half full turns in total. Getting this right matters: if the rotation in the driver, the game and the car you're driving don't match, the steering feels too slow or too twitchy, and the wheel on screen moves differently from the one in your hands.

With 900° of rotation, the wheel turns 450° to each side. The game can add a soft lock that stops the wheel earlier.

Common rotation values

RotationTypical use
900°Maximum on many entry-level wheels, and a common value for road cars
1080°Maximum on several belt-driven wheels; useful for road cars and trucks
540°Often used for GT and touring cars
360–400°Formula and open-wheel cars, which have very direct steering
900–2520°+Direct drive bases can often be set very high, for trucks or vintage cars

These are typical ranges, not rules. Each real car has its own steering ratio, and many simulators use the right value for each car automatically.

Who decides the rotation?

Usually two places:

  1. The wheel driver or wheelbase (G HUB, Thrustmaster control panel, Fanatec's tuning menu, MOZA Pit House) sets the hardware rotation: how many degrees of turning map to the full axis range from −1 to +1.
  2. The game may apply its own steering lock. Many sims read the hardware rotation and then limit it to match the car. This is soft lock: the force feedback motor creates a firm stop at the car's real steering lock.

Problems start when the two disagree. For example, the hardware is set to 540° but the game assumes 900°, so the on-screen wheel turns much further than yours. Or the hardware is set to 900° but the game expects 540°, so you have to turn a long way before anything happens. For most modern simulators, the recommended approach is to set the hardware to its maximum (or the value the game's documentation suggests) and let the game apply soft lock per car. Check your game's recommendations, since some arcade-style games prefer a fixed value.

Steering ratio

Some games show a steering ratio instead of degrees. A ratio of 12:1 means 12° of turning at the wheel gives 1° of turning at the front tyres. A higher ratio makes steering slower and more precise, while a lower one makes it more direct. When the rotation and the car's ratio match the real car, the on-screen wheel turns 1:1 with your hands.

Check it with the wheel tester

  1. Open the wheel tester and set the rotation to the value in your driver.
  2. Turn the wheel to full lock on both sides. The axis should reach −1.000 and +1.000, and both “full lock” checks should be ticked.
  3. Turn the wheel exactly 90° (a quarter turn). The tester should show about 90°. If it shows much more or less, the rotation set in the tester doesn't match the hardware setting.
  4. Hold the wheel straight and press “Mark center”. The offset should be well under one degree.
Axis stops short of ±1?

If the steering axis only reaches ±0.9 at full lock, the most common cause is an old calibration in Windows or a rotation limit in the driver that is lower than the physical stop. Reset the calibration in joy.cpl and check the driver. See calibrating in Windows.

Linearity, sensitivity and deadzone

Games often add a steering sensitivity, linearity or gamma setting on top of the rotation. Leave these at their neutral values (usually 0% or 1.0) while you set up the rotation. Otherwise you'll be adjusting two things at once. A steering deadzone is almost never needed on a good wheel, because any deadzone around the center makes the car feel vague on the straights.
