Tyre pressures

(1/3) > >>

Carrera2RS:
Anyone run different to standard. My tank cap says 2.6Bar, just under 38psi. This seems a lot, I noticed that my wheels are currently 32 all round, so I will add a few more psi, but they do already feel a little 'hard' I was kind of hoping I might be able to lose a few psi.

My car is a Pirelli with 8x18 TD's fitted.

stealthwolf:
The tyre pressures can and should be varied to suit the conditions.

I when I took my car in for its first service, I had them set at 37psi. When I drove home, the steering felt very heavy and the car wasn't as nimble. The dealers had dropped them down to 32psi. I promptly stuck them back up to 37psi and the car was fine.

Use trial and error to find what suits you but remember tyre wear will vary according to the pressures.

Richn83:
Whats your tyre width, if your running 8" wide wheels I assume it might be wider than the standard 225 tyres on all the GTI's and this will affect the pressure you need to run.

I run 2.65 on my fronts and full load pressure on the rears 2.9 bar its possibly a little hard but I prefer that to soft and wobbly and can feel when one of the rears gets low.  Before anyone asks I run the full load pressure even when the boots empty saves having to change it when I load the boot up or take on extra passengers and I would rather run higher pressure than too low a pressure.

the bruce:
The pressure you need depends on:

- load index: '88' needs more than '92'
- weight of the car front + rear
- speed: Vmax needs more than country
- camber: extreme camber > more pressure needed
- driving style/preferences: GTI > more lively rear > same pressure front + rear

Have a look at the recommended pressure of A3/Golf 2.0 TDI. These have the
same weight as GTI.
Recommendations are lower !! One reason ist the lower speed. Then these
recommendations are different front + rear. I guess 2.2 and 2.0 bar.

The pressures will be a good fit for a GTI as well. But then you should not
run 250 km/h.
Now you know why VW recommends higher pressures for the ED30, which
is not heavier but just faster.

I'm not a friend of rising pressures to make the car feel stiffer. This reduces
the contact area and so reduces grip.
So it's clear that a GTI is faster in corners than a ED30.  :P

It's a main mistake to put too much pressure on the tyres.  :wink:

keano:
Will 35psi be okay front and rear?

The only extra weight in the car is a slightly chubby driver  :grin:
