anybody know what tyre preasure i should be putting in my tyres, the specified preasure is 28psi up to 3 passengers or 30psi if fully loaded,
the tyres originally should are 205/70/14
ive have fitted cooper gt radials - 235/60/15 on the rear & 215/60/15 on the front so i presume those preasure specs go out of the window, if i put 30psi in each they look flat especially the front ones! the preasure stated on the tyrewall is 44psi max so i have had them pumped up to 38psi the ride is good and they look ok but looks aint everything, safety is more important

Between 30 and 35 will be good. If you put too much pressure in the tyre will have less tread contact with the road surface and the tyres will wear in the middle faster than at the edges.

cheers dave as usual your good for an answer. 35psi it is then all around

But make sure you have FULL tread contact with the ground. I don't want you spinning off in the wet.

I usually have about 32 in normally and then pump them up to 36 for long distances just to get a little more MPG. At the track the fronts get 45psi.

dave how do you check for that? is it visible on level ground?
the fronts sure look flat with only 30psi in them,
sorry if i sound like an idiot but never had to ask about tyre preasures before always put in what the book says but this isnt a standard application - well not in my eyes, and as you quite rightly stated i dont want to be sliding around in the wet

Put the car on a smooth surface and look at the tyre edge on. If the outer edges of the tread are starting to lift off the ground you have too much pressure in.

The rears are easy. Just lay some rubber down and measure the width of the black lines compared to the width of the tyre tread.

i like the sound of that check!!!
