(2006-) D4D Ride Quality - whit5892
My wife and I have owned a Yaris II D4D for just over a year. We enjoy the car in all respects except for the ride quality. Over what masquerade for road surfaces in this country today the Yaris gives us what we regard as an extremely harsh ride. Some of this is attributable to firmer springing to cope with the extra weight of the diesel engine, but even allowing for that we still find the ride too harsh. Another factor which must contribute to this harshness is the tyre pressures. Why is it necessary for the front tyres to be inflated to 36psi? Has anyone any experience of running at lower pressures and has anyone found other ways of improving the ride quality?

Tyre pressures are set so that the tyres do not give too much side bulge for the weight they carry, if the Yaris has alot of front end weight, the pressures will be high, sometimes common on heavier diesels. However you maybe to get away with dropping the pressure 1 - 2 psi. Another option is to change to a softer tyre, but may not last as long. If the pressures too much on my ford, tends to affect handling, cornering and wear patterns on tyre.
