Hello,
I have a new-style 308 bought just over a year ago, a 1.2 Active 130 hp hatchback with 205R55-16 tyres.
The rear tyre pressure is given as 2.3 bar (33 psi) minimum (presumably driver only) and 3.3 bar (48 psi) fully laden, which seems a massive variation to me. My previous car, a 406 Coupé, specified 35 psi all round regardless of load!
My question is, whether there is any sensible compromise. Until a couple of weeks ago, I had been running the car on unladen pressures, 2.4 bar all round. However, I then had to drive from Hampshire up to Edinburgh and back - going on my own and returning with brother, wife and a bootful of thier luggage. Not wishing to faff around changing pressures en route, I compromised and left the front tyres at 35 psi, and increased the rears to 40 psi.
At present I have not reduced the pressures and the car seems to ride and handle very well. It also seems to be benefitting mpg.
I am aware that some Vauxhalls suggest higher "eco" tyre pressures.
Are there any downsides?
I asked the Goodyear helpline (the original equipment tyres are Goodyear EfficientGrip) but they had no advice, referring me to the car manufacturer. Peugeot in turn do not answer technical queries on their helpline, referring me to the dealer... All the dealer has to offer is the published information.
Since one is often alone in the car, but rarely fully laden, and frequently with apart load that can be anywahere between these two extremes - does anyone have a practical solution to cover most normal use without endlessly changing tyre pressures?
I would be very surprised if anyone does!
