Tire pressure for Michelin Super Sports? Pictures uploaded.

Any help would be appreciated!

Hi, The max pressure is 51 psi which of course I will go nowhere near. I have put ""43 psi"" (potentially not a calibrated machine) in the fronts as they have a veryyy slow puncture over 3-6 months and always have done over the last 3 sets, the tire pressure lights comes on after being reset constantly, even after cleaning the seal area thingy around the rim, it's not an issue for me. but they do look a little flatter than the rears even at 43 psi. Having just put 43 psi in the fronts there is still a noticeable difference to the rears. (It was done at an ASDA tyre inflator which I believe are not calibrated).

The fronts look fine, but they are flatter than the rears.

What is the recommended pressure as I don't want to sacrifice breaking and cornering performance for road use, so should the fronts look about the same as the rears? I'd prefer to have a pressure that's good in the wet and dry as I have a daughter.

Again, any help would be appreciated!

Firstly, I’d get the puncture repaired - I wouldn’t knowingly drive around with a slow puncture.

VW’s recommended tyre pressures should be on the tyre pressure sticker - either inside the fuel filler flap or at the bottom of the driver’s side B pillar.

Cheers! I'll have a look and check the pressure.

I've been trying to correct the slow puncture for the last 18 months and 3 sets of tires, had the inner seal rim thingy cleaned 3 times etc, had the wheel checked for any damage visually, then a machine I didn't know existed looked to see if the rims were completely round and had no flat spots from pot holes etc. It is a mystery. The only explanation that 2 different tyres places and I have logically come up with, is that because I do a lot of miles I will therefore lose more air naturally, enough air escapes to turn the tire pressure light on. Never happened on any other vehicles and only doing 30k miles per year

36psi was/is the recommended pressure unless you've got a car that was made when VW were trying to get cars wltp passed in which case it went up to 41psi.

So... questions:

1) Do you actually lose tyre pressure?
2) Have you had the ABS unit checked on the hub? (This is how the car detects tyre pressure drops)
3) Have you had a new valve in when getting the tyres changed?

Will the fronts look marginally flatter? Of course, there is more weight being carried across them than the rears, so there will be a slight difference.

Here is a tyre pressure label for reference (for 18in alloys like yours):

Presumably it is just the one tyre that loses pressure? The system compares wheel rotation between the wheels on the same axle to check pressures. Tyre pressures do change winter to summer but both should be very similar. Can only think abs sensor as Agreable Slick suggests, valve not seating properly due to damage or damage to the wheel itself but not the rims since you have had these checked.

Take the wheel off and spray all over with a mix of water and washing up liquid. If you do have a slow puncture on wheel or tyre it will definitely show it with a mound of tiny bubbles.
