Tyre pressures?

What tyre pressures are people using? I checked mine today after owning the car for a month or so, all 4 are approx 36 psi. According to the handbook the standard pressures are 41 psi all round, while 36 psi is given as the 'comfort' setting which may result in worse efficiency.

I find the ride quality at 36 psi pretty good so reluctant to go much firmer.

I have Bridgestone Turanza which I believe might be OEM - I don't rate these much but they have plenty of tread so not worth replacing yet. I had Pilot Sport 4S on my Golf R & they were great.

I may experiment with 38 psi but agree 41 might be too firm - I live in the countryside & the local roads are terrible.

What he said⬆⬆.
Had my eGolf 4.5 years and tried the suggested range of pressures, roads are generally ok where I am so I keep them at the high end as I prefer the sharper feel. Suggest achievable mileage difference is really not that significant, if you are running the battery to its extremes and you prefer comfort then just slowdown a bit and you will offset the range impact of lower pressures.

I tend to run 36 - 38 psi. Higher feels too firm and jolty over the country roads around me.

I might consider increasing the pressure to 40-41 if I've got a very long motorway run on good roads, but to be fair I hardly ever do those kind of trips and I'm unlikely to remember anyway.

My golf GTE specifies 33-36 front and 33-41 rear, I go 36 all round. I’m more concerned about even tyre wear and range than comfort. The results are pretty even wear with slightly more wear on the edges than middle inferring that another PSI or two would be optimal. (The GTE doesn’t half go through front tyres. The electric torque is too much for FWD pulling out at T junctions.)

These are pretty exotic pressures and you might find that “professionals” set much lower pressures that would be typical of an ICEV hatchback.

If the information on the B pillar says 41 psi then you should not be below that, preferably over, but not under. Higher pressure reduces wear as well as consumption, and also increases stability. You might find it more comfortable, but personally I feel as the tires feel "spongier" when not inflated enough and they wear a lot more and the consumption noticeably increases. I inflate about 2-3 psi over the recommended in our cars and that works fine and feels best.

To start with, there is NO WAY that anyone can blame you for that if your tires are good. It will NOT cause skid unless it is extremely overinflated. A few PSI, like 2-3 I said, is within the error margins and the precision of the instruments used, plus there are quite significant differences between compressors also. In fact, under inflating causes more significant instability then the slightly higher pressure. If the tires are under inflated then the car will wobble in curves, and if you are unlucky you will lose control. If you skid with a slightly higher pressure then your tires are worn out or you are driving too fast, or something else is wrong. The cause is NOT 2-3 PSI extra. Also, if it is winter and there is any snow or ice then you WILL get better grip with slight over inflation, as opposed to under inflated tires. Also in rain a slight over inflation is better, it will give you better grip and LESS risk for skidding, not more. But again, tire conditions, as well as a lot of other things matter also, nevertheless, 2-3 PSI over is better then 2-3 PSI under. Another thing is that as you can see in that picture above your post, the RECOMMENDATION has a large variation. Also, the values are changing a lot between load situations, but do you honestly mean that if you drive with 5 persons then you pump 38 / 41 and then when you dump two of the passengers you immediately change pressure to 35 / 34 PSI ? because if you don't do that then you drive with over inflated tires according to your own warning with that car... after all, you said that "You should never over inflate tyres" :)

My e-Golf is set at 36 all round - which is what it was delivered at. I tried the higher setting of 41, but found the ride quality on rural North Wales roads far more harsh, not to mention more road noise.

Now that the weather has improved, I'm averaging 4.2-4.3 miles/kWh, and that's driving in Comfort mode with the aircon on full auto. I suppose it would be better with the higher pressures and Eco mode, but I'm happier with the lower pressures and better comfort
