Hi,

Anyone seen the suggested tyre pressures on the Vreddy website there massive!! For the standard 225/45 17's it says - 44psi front 42psi rear

Putting 235/40 18's on mine very soon.

Anyone who already got Vreddys on advise on what pressures your running at?

Thx

 

i just run the standard pressure 2.3bar upfront and 2.2 rear.
seems good.
be interested in what other people are running

 

Yep, thats pretty much what I'm running now in my T1R's - 34psi front 32psi rear.

Have heard that its something to do with the XL (95 load rating) for the sessantas???? But an extra 10psi in the front and the rears!!

Would really like to know what people are running - especially if anyone is actually running at the listed pressures?

 

I'm just running usual and I have 19's so 34psi all round, seems fine to me. I think I might up that a bit now thou

 

I use the normal figures of 33/29 on 225/40-18 Sessantas

On 17" Sessantas Im running, though may increase them a tad: 32psi Front / 31psi Rear

 

i run 36/34 on my 18s

 

Cool, everything OK?

What do you think to the vreddys - I heard loadsa good reports?

Thx for all your help people

 

everything is fine,even tyre wear fantastic grip in all conditions I will definately be getting these again on my next car

 

I run 37/35 but probably closer to 36/34 as I don't do pressures more than once a month. Vreddy's are a great tyre I have them in 235/40/18 and 235/45/17. I just hope they stay in the premium budget price range cause they punch so much higher than the price.

 

Really? That seems very high - do you have a link to that page?

I run the Prodrive recommended settings (I think it's 33F/31R but I don't have the paperwork handy).

Don't have it at the moment, but if you go on Vreddys website and use tyre selector enter your car details it comes up with suggestions and psi figures

 

Just done it and sure enough they come up as 44F/42R. I've completed their technical question form to ask if those are correct and why they are so much higher than the Subaru/Prodrive settings.

See what they come back with.....

Dibs

 

Curious to this myself, run at 33/32 in mine, feels fine, seems a bit odd to be that high.

 

Good idea. If you could post their response on here would be greatly appreciated.
Seems way too high to me which is why I posted on here
, but suppose they're the experts on their own tyres,

Thx

 

they are high load could that be why the pressure they give are so much higher?
dose the pressure not relate to the weight of the car they are on?

there load index is 92 so can take 2520 KG

 

Will do.

Dibs

 

I am a GDS3 diehard...but hearing such goodthings about these. I will give the ago when the time comes.
Out of interest. anyone have to hand - what maximum speed these tyres rated to? (17in)
As I have been known to max my car out down the odd autobahn

 

Both the GSD3's and the Sessantas are Y rated 186mph/300kmh.
The Sessantas are a higher load rating '94' GSD3's are '91'.

 

One other little point:

I believe the Sessantas are Asymmetrical?
This means that its the same tyre all round the car (ie. they are not directional) although they do look it - is this right?

Comments from Vreddy users?

Cheers

 

That's probably the 'hot' pressure rating. i.e when the air in the tyre has heated/expanded due to use. just a guess?

 

Not sure, but I wouldn't think so as tyre pressures are normally quoted 'cold' and there isn't any mention of the tyre being hot or an alternative psi for 'cold' tyres. IMHO

Tread pattern still confuses me though Vredestein

 

cold tyre pressures are only 'loose' estimations by the tyre companies/car companies of what optimum hot tyre pressures will be reached in average conditions, and that can probably depend if its a track tyre or a road tyre.
the cold pressure starting point all depends on weather, atmospheric temps, road conditions. So cold pressures need to change significantly to reach the optimum hot tyre pressure for proper tyre performance.

 

I'm running 35fr 32rr.

I was running 36/34 on mine but upped that to 40/38 after reading the recomended pressures on the Vredestein site. Seems to of made little difference tbh.

 

34/34 for me

 

Tread pattern is a tad confusing, they do look to be directional, thought something had been puton wrong the first time i had my wheels off for something!

 

I had an email back from Vredestein today which looks to have (partly) cleared things up:

This is the answer from our Tyre Information Centre to your question:

The tyre pressure we advise for your car is 39 PSI on the front and 38 PSI on the back.

We always recommends a tyre pressure for maximum load.

We do this because our experience is that the pressure is not checked regularly. It is normal for a tyre to lose a bit pressure after a while. When the tyre pressure is too low the tyre wears faster en the car is using more gasoline. If you always drive alone we advise you to put the pressure on the tyres which are recommended by the car manufacturer.

This is for a MY2007 2.5 STI Type UK by the way. I just checked the maximimum load (5 plus luggage) pressures on the door shut and they are 36F/31R so still not as high as Vredestein recommend.

It looks like if you check your pressures regularly (and I hope we all do!) then you don't need higher pressures and that "regular" pressures are OK with these tyres.....

Also, they are not directional, they are asymmetical - see here

Thx for that Dibs - very much appreciated

Looks like I'll be stayin' with my usual 36f/34r (and check them regularly of course).

Ordering some 235/40/18's this week.

Cheers gents.

 

Being asymmetrical makes them directional! They have to be fitted the correct way and therefore are made to travel in the correct ONE direction. You can NOT rotate them and run them the other way.
Edited to add, i cannot believe you only check your tyre pressures once a month at best!
I do mine once a week and the snow was the only thing that stopped me recently from doing it. I am paranoid, but after all, those 4 bits of rubber are the only things keeping you on the road.
