The Merc is currently equipped with ‘All Weather’ tyres, or if you’re foreign, tires. If you are one of those philistines that regard tyres as simply black circles then I urge you to read The Intercooler, available as an app. That small patch of rubber on each corner of your pride and joy is what keeps you on the road, delivers communication from the asphalt, squeezes the water out to prevent aqua planing and yet is soft enough to grip the surface under hard braking or cornering.
Around September 2019 after a couple of months of ownership I decided that the distinctly underwhelming and overworn tyres needed replacing. Graham at Oatlands Tyres of Harrogate suggested Vredestein Quatrac all weathers. I toyed with the idea of getting a set of wheels for the tyres so that I could run both summer and winter tyres, an idea that was dashed on the rocks of fiscal reality. Graham assured me that these tyres were more than adequate and indeed after over 30,000 miles on the rears they have fulfilled that promise. Moreover they have proved their worth in adverse weather.
They can be fairly noisy on motorways, the section on the M1 link road with a concrete surface renders Radio 4 inaudible, but generally I am very happy with them. The fronts have been replaced because of punctures and potholes, sadly with plenty of wear left, but the rears could last another 10k. However Vredestein Quatrac tyres prove their worth!
