Air pressure

[Huskyxantia]

This thread ive started is about the air pressure we put in our car wheels.

My 206 claims to have a maximum 44 psi, i was running 35 then went to 43.5 psi how ever this difference has made the ride hard. My tyre size is 195,50,15 im considering r7nning back to 35 psi again for a less harder ride .

How comes what the door post sticker says is different to what the wheel reads and what a tyre fitter will put in ?

Any suggestions ?

Of course the lower the pressure, the softer the feel to the vehicle, as under-inflated tyres will have a 'cushioning effect' but under-inflation present risks which result in more of the tyre's surface in contact with the road, leading to more friction, overheating, increased wear, blowouts or other issues.

The door sticker should be the correct tyre pressures for the specific tyres recommended (factory-fitted tyres) and these may show a range of pressures including the maximum pressure depending on the loading of the vehicle, but should never be under the 'normal' pressure stated.

I always tell the fitter what pressures to use and will always double check these myself at an independent garage or at home and adjust as necessary as they can be incorrect.

Cheers marc, will be checking my front ones again in the morning.

Great topic! It's the only 4 inches that keeps our cars on the ground.

.... and what a tyre fitter will put in ?

Any suggestions ?

A fitter will put whatever they like in, a seemingly random number picked out of their mind, depending on what day it is. I've given up telling them and just check them myself when I get home.

I stick to the pressure that the car/motorcycle manufacturer has recommended on the sticker on the door pillar (or swingarm). If I'm riding the motorbike when it's likely to be icy or very cold, I drop the pressures by 3 or 4 psi. This, I've found, doesn't set the TPMS off on the bike - 5psi does. It does give a little more grip, but it doesn't half square off the rear tyre and wear the centre away. Had my SV650 down to the cords!

Its all about finding that sweet zone

So the door pillar sticker is correct , would this be for different makes of tyre be it budget or top spec , the same pressures ?

The door label sticker is the manufacturer-issued one for the vehicle, with the tyres fitted at new when it left the factory.

According to your VIN this is what you should have as it left the factory:

16 INCH OURAGON WHEELS (Alloys)
205 X 45 X 16 W TYRES

So the tyre pressure sticker should match the tyre sizes.

That's interesting marc what's on the car now is 195 50 r15

If it's same as 306 (think so), then the 15 inch wheels you have should be fitted with 195/55R15
These are commonly substituted with 195/50R15 as the 55s are much more expensive (e.g when I bought some Uniroyal rainsport 2 for my 306 it was:
55 = £75 each
50 = £50 each!

I'd go for the door sticker pressures, even though you've a different wheel/ tyre size.

All makes sense

Hi Matt - Husky is referring to his 206 Cabriolet, not his 307, so has16" wheels fitted as per my post

[MattBLancs]

I was going off this!

Thought they were the 15" wheels (sometimes known as Quicksilver wheels, can't recall their proper name)

Hey ho, feel free to ignore me with wrong end of the stick!
