I purchased a new VW Polo Match a couple of months ago. I'm finding the ride is much harder than the VW Golf Mk7 I had before. The tyre pressures for the new Polo are 36PSI all round. The Golf had tyre pressures of 30PSI all round, even though it was a slightly larger car. I think the wheel and tyre sizes are the same on both cars. My question is why does the Polo have such high tyre pressures ? I think this is what makes the ride feel so hard. The suspension copes with big bumps and dips in the road quite well, it just bounces and jiggles around a lot on the smaller road imperfections. This suggests to me that the tyres are too hard. Would it be alright if I was to try lowering the tyre pressures, perhaps to 33PSI? I realise that I would have to reset the TPMS accordingly.
