Today was my first real chance to try out my new tyres. The roads were dry, but it was a cold day. I covered about 90 miles of mainly motorway/dual carriageway driving with some country roads and a bit of town driving thrown in. The ride was smooth, but I was more aware of expansion joints, cat’s eyes and warning stripes than with the Bluearth ES32’s previously fitted. Mind you; I have not checked the tyre pressures yet. They may have been set a little bit too high. I was surprised to find the noise level was better, but I think that was due to the removal of the Mentor tyre I had on the rear offside. I can now hear the engine instead of just tyre noise. Previously, I sometimes thought, due to the propensity of wheel bearing issues with the Jazz, that that was what the noise was. However, I would then go over a super smooth section of motorway, and the noise would disappear completely, not something that would happen with a wheel bearing. The stretch of tarmac I mentioned near the Sheriffhall roundabout is amazingly quieter.
However, the car doesn’t coast as well as it did. According to my ScanGauge, today’s mpg was 53 instead of an expected 58 – 60 mpg.
