Hi all, what tyre presure should i be putting in my new wheel & tyres, 195/50/15 , these will be going on a Mk indy. cheers
Start with 18psi per corner and see what its like.
I'm running about 16 on mine [same size tyres].
Stu
running 18 psi
i drive back from stoneleigh last year with a flat front and didnt even notice as the cars so light.
but i try to run 18/20
16 at the back and 14 fronts for me.
Run either 18 or 20 psi in mine
thanks for your replies, will try 18psi and see how it handles.
I run 18 psi front and back on my 850Kg V8 powered seven. I read somewhere that it is unsafe to go below 15psi as there is a risk of the tyre coming
off the rim below that level I think.
Another thing I read about was to draw a chalk or crayon line across the tread and then drive around and check the line every so often. If it wears
away in the middle first then the pressure is too high. Run the highest pressure that still gives even wear on the chalk line but don't go below
15psi.
One last thing - in wet weather you might want to raise the pressure 3 psi or so to delay the point of aquaplaning. It does this by increasing the
pressure in the centre of the tread which helps to push water outwards rather than trapping it under the tread.
Remember to check pressures when completely stone cold.
HTH,
Craig.

However most find that a cold pressure of around 16-20 Psi works well.
I have to say Matt Craig as a very valid point especially regarding the link above, your advice is no different to any of the above in fact it looks
like they have all copied and pasted your own advice.
Must admit it made me cringe with embarrassment for you when I 1st read it, decided not to reply but as Craig as thought I would share with you how
appeared to come over to me to.
There's no doubting your technical ability but as an outsider looking in your response did you no favours whatsoever, your not dealing with SAM68
types here, just a fellow enthusiast who wanted a ball park starting figure for tyre pressure.

Just seen this just now.
I don't know Matt so I wasn't sure if his (apparent) posts were typical of his sense of humour or whether he had just had a bad day and was
letting off steam or whatever. Either way I felt it necessary to make my feelings known.
I'm glad to hear that it wasn't him who made the posts although whoever did make them was quite clever about it and was able to make it look
pretty convincing. Hopefully once Matt regains access he can come on the forum and clear things up. I'll put my handbag away now... 
Maybe a good time for all of us to think about changing our passwords...
Cheers,
Craig.
