Tire Changes on an AWD Toyota Previa
Rear tires: One of them is now worn out and has a "bump" on it. Shakes the van at slow speeds. The other has 12-20% tread left on it.
Front tires: 50% tread left on them
All four are Michenlin X-ones.
Do I need to replace just one, two or all four. Does this effect the fuel consumption?and does it affect the drive traction controle etc?
I was told that the van senses the wheels when it is driven; all four tires must be the same brand etc.
Please help.
