Strange tyre temperature issue


Hi all see my tyre temp, the right front (im in Australia so driver is rhs) is consistently 5 to 7 degrees hotter than the other tyres.

Anyone know why, and for longer term is this an issue or sysmptom if something more serious?

Normal. Being built for the left hand market if you weigh the car you'll see weight on the left front tyre is about 485kg but 515kg on the right. So it shows engineers tried to balance the weight of the driver for left hand cars. That's why the right hand drives cars always have hotter right front tyres.

Oh that's why, thought someone mentioned there is an aux heater there or something. Others suggested it is due to exhaust heat.

Still happens with LHD. You are probably right in principal but the right front tire is still hotter with a LH driver and I fit the average driver profile, male 1.8m/80kg, that the Germans use as the reference when designing cars. I'm actually even slightly heavier. If I remember correctly, the reference driver weight is 75kg.
