New Vreds

One of my RF's went flat yesterday so it made my decision to buy a full set of Vred Sesantas which will be fitted tomorrow. What pressures should I be using.

The tyres are

255 35 18 and 225 40 18.

Ta.
 
That's going to make such a difference to the drive of your Z :) + they look great :)
Pressures have been discussed before but ballpark for mine were 34/36 fronts 36/38 rears .
Others ran different so maybe see what your fitter recommends :thumbsup:
 
I pick my first zed up on Saturday and I am getting the alloys refurbished on Monday and removing the run flats and I have just bought a new set of vreds to be fitted on Monday :)
 
I've always wondered about suggested pressures of tyres.

For my old car I found that the factory recommended pressures were too high and that the car handled significantly better at lower pressures.

Surely what pressure to use is purely down to trail and error?
 
Just remember when you put new tyres on, they will need run in for a few hundred miles. They'll feel a little squirmy for the first couple of hundred miles, then settle down again. After that the grip will come through :thumbsup:

interesting, when you say better to do you mean smoother, quieter, grippier etc. i guess there could be an argument for saying lower pressure = better contact patch as the tire squidges more but this must be a very fine balance between too low so tire is not inflated enough.

ive always wondered if there was a difference in pressures between run flats and non run flats.

i would imagine the pressure wil be a calculation based on weight factoring the strength of tire wall, profile, size, type.

its interesting as i run the toyo t1r tyres on my westifeld at 18psi. but then again it quite light so taking a decent dump before going out makes a difference :o
 
Thanks fellas. I'll start at the low end of your rec's Mr. Wilks and see how things progress. I don't want them wearing in the middle. I also appreciate the benefits of regular tyres as I did the same thing with my old e61. It was like night and day.

How much did you pay for yours Andy. I got mine from Tyreman at £424 delivered. They will cost £12.50 each for fitting and balancing and I'll hope to recoup a bit by eBaying the RF's. They've still got a fair bit of tread and the 1 that went flat hasn't lost any air since it was pumped back up on Wednesday.

Thanks for the tip Adamski. Slow but sure until they're scrubbed in.

Looking forward to getting them on once the courier gets his ass into gear and delivers 'em.
 
The thing you have to remember about tyre pressures is that 1psi is around 20-30lbs/inch of spring rate.

So, lowering the pressure of your tyres will give a more forgiving ride, but going too low without replacing the springs will make the car sloppy and unresponsive when cornering. You'll wear the shoulder of the tyres out too if the pressure is too low

All fitted and even the 5 mile drive back from the fitters was a completely different (read good) experience with the Vreds.

The 1 that went down on Wednesday was a total write off. If you've never seen a RF that's been used when flat you will know that they end up full of side wall that's turned to dust. The other 3 will be up for sale on here later today.
