Comparison ThrustMaster T128 vs ThrustMaster T248

The size of a gaming steering wheel usually refers to the diameter of the wheel in round and D-shaped forms and affects the realism of control, rotation speed, and grip comfort. Compact wheels, around 20 – 24 cm, are more common in simple models and are suitable for arcade racing but feel less realistic. A size of 27 – 30 cm is considered more versatile and closer to an actual car steering wheel, making it convenient for simulators, GT, rally, and everyday play. Larger wheels, 31 – 35 cm, are more often used in advanced setups, especially for trucking simulators, drifts, or the most realistic seating.

For formula wheels or steering wheels with a cut-off shape, the size is more often indicated by the maximum width between the outermost grip points.

The total number of buttons provided in the manipulator's design.

The more buttons, the more additional functions can be "assigned" to the manipulator, reducing the likelihood of having to use other control devices (e.g., a PC keyboard) during gameplay. However, many gaming consoles (see "Platform Compatibility") require a certain minimum number of buttons for a compatible gamepad — having fewer buttons would simply not allow full use of all the console functions. For instance, the standard controller for the PlayStation 4 has 11 buttons.

Note that the D-Pad manipulator (see below) is not counted in this calculation: it is considered a specific control device, although it is based on buttons.

The max. torque indicates the force with which the steering base can resist turning the wheel. Simple wheels typically deliver about 1 - 2 Nm, more advanced models provide 4 - 8 Nm, while powerful Direct Drive bases can deliver 10 - 20 Nm and above. The higher the torque, the more pronounced the sensation of tire grip, hits, drifts, curbs, and the load in turns, making the control feel closer to a real car.

In simulators, the force is often adjusted for the game, car, and user's comfort. For example, a small force is sufficient for arcade racing, while for iRacing, Assetto Corsa, or serious drifting, a powerful base with reserve torque offers more precise and rich feedback.

The steering wheel rotation angle in the control wheel (see "Device Type"). This parameter is measured by the total range — from one extreme point to the other; accordingly, the rotation angle from the mid position will be half of the total. For instance, an indicator of 180° means the wheel can turn both right and left by 90°.

This parameter directly affects both the overall level and the purpose of the wheel. Models with a rotation angle up to 270° are predominantly entry-level and are mainly intended for arcade racing enthusiasts without a significant emphasis on realism, as well as for children and beginner gamers. More advanced wheels have a rotation angle of 900°, or even 1080°. These figures are not arbitrary — they correspond to the steering wheel rotation ranges in most production cars (900°) and some racing supercars (1080°). Thus, such features make using the wheel as realistic as possible — on the other hand, they significantly impact the cost.

The range of steering wheel rotation can be adjusted by the steering angle adjustment function (if this feature is implemented in the game controller). The option is set either directly in the game or through the software that manages the wheel's operation.

Types of pedals included in the manipulator package.

This parameter is specified only in controllers designed for auto racing (in flight simulators, pedals have only one specialization — rudder control — and specifying it further is unnecessary). Most of these "racing" controllers are wheels (see "Device Type"), however, pedals can also be released completely separately. In any case, the minimum necessary for more or less effective car control is two pedals, gas and brake. Meanwhile, for enthusiasts of maximum realism, more expensive three-pedal controllers are produced, which also include a clutch; this complicates control but provides many additional possibilities unavailable with two pedals.

A small screen that can display various information for the player, notifications about battery status, network connectivity, and more. The specific functionality of the display depends on its implementation on the gaming controller. For example, on racing wheels, the screen often shows speed and/or lap time, while on advanced gamepads, it may indicate the player's health level, ammo count, etc. In any case, the display provides useful information without unnecessarily distracting from the gameplay.
