Do you ever change them ?
I have a facelift estate, just wondered what you run you pressures at ?
-
36 psi all round. one of the other members found it too be a good match of handling and MPG
Granted it sounds a tad high, but I get better MPG over the stock settings, a slighty harder ride and after 4000 miles no iffy tire wear
-
Im about the same ... 36 rear and 34 front... mines a saloon though .... :y
-
I use 34psi all round on my saloon. Seems to be ok after 10K
-
used to run 31 all around, tried 36 psi, last couple of tanks after markdtms post.
Got a fraction more out of a tank, maybe 20 miles, but the ride was too hard for my liking. Will drop back down to 31.
-
32 all round but 235 wide tires on a saloon. Dont really want to go much higher, keeps it out of the ditch.
-
I pumped my rears up to 36 when I had a heavy load in it about 6 months ago and forgot to let the pressure out. They started to show signs of overinflation (centre wear) so I think that is a little high for my driving.
You have to remember that what's right for someone who does 90% motorway cruising will not be right for someone who does 90% urban driving. Equally, if you fling it around all the time you'll have different requirememnts to someone who drives sedately.
Add to that the fact that gauges are not generally that accurate...
Best to experiment and find what suits you, I say.

Quite so, same goes for the whats the best tires question... Whats best for a sedate high mileage, one set of tires per life time driver, wil very bad for an enthusiastic driver who hates climeing trees, and vice versa. All depends what you want from them...

My saloon runs at 32 PSI
-
was using 30-32 psi summer-winter but after Mark DTMs post I increased to 34..
-
235 x 17 - 32 psi all round here too. The rears are down to the wear bars now and they have worn slightly more in the centre. So possibly still a touch too high.

What post CEM?
TIA
-
i have my 235x17's at 30/31 seems fine for the wear
-
35psi all round on my Nankang Ditchfinders,seems to suit me. :)
-
My saloon is 28.5 front, 31.5 rear. Great mpg. I do lots of motorway driving and the wear is very good.
It's worth getting a decent pressure gauge though because I've come accross so of the automatic ones which are as much as 1psi over.

Are any of these any good?
Have only listed the Buyit now ones.

Some time ago he summarized his test for tire pressures and said 36 psi was optimum in his trials for consumption and handling..
-
My saloon runs at 36psi all round, no noticible wear yet.

I can't say, but I would not have thought so because it says accurate tpo +/- 1psi - which sounds quite inaccurate ;D
I've gote one of these - http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_178469_langId_-1_categoryId_76861. Only 9.99 from halfods and accurate to 0.5psi. Plus does Bar/Psi and you can read it at night time too.

I've been trying to find optimum pressure for the rear tyres. Usually have 32psi in fronts (235x40x17) and used to have the same in the rears which are somewhat wider at 265x40x17. Trouble is I found the rear tyres were wearing in the middle which would suggest that pressure is too high so I've now dropped them down to 30psi. :-/

I wouldn't be surprised if you need a bit less pressure in those! You've got a larger contact patch with the same weight on it after all.
The 205/50/15s on my Westfield are best at about 18 PSI. A bit lighter than an Omega then... ::)

So would you think they need to go a tad lower than 30?
-
For nice sharp steering and normal tyre wear 36 front.Run the rears 30/32 as even 32 can give you wear in the middle if you drive one up most of the time
-

Not necessarily. Just keep an eye on how they're wearing. The biggest variables are what type of driving you do and with how much load in the back.

The wheels are Azev A's, 8.5Jx17H2 on the front and 10Jx17H2 on the rear.
