Think I already know the answer to this but how does TPMS handle aftermarket wheels?
Doesn't matter as long as you reset it...
Indirect TPMS do not use physical pressure sensors but measure air pressures by monitoring individual wheel rotational speeds and other signals available outside of the tire itself. First generation iTPMS systems utilize the effect that an under-inflated tire has a slightly smaller diameter (and hence higher tangential velocity) than a correctly inflated one. These differences are measurable through the wheel speed sensors of ABS/ESC systems.
On that basis, once the TPMS has been reset the sensors should work off the current values of the new wheels, then any changes would trigger an activation.
Does anyone know if the newer generation 8V uses indirect or direct TPMS?
If I do pick up a new set of wheels I'm wondering if I need to purchase a physical TPMS and have it fitted inside the alloy.
Ah nevermind, I should really read the manual before posting silly questions like this lol
