Now i am sure that somewhere in my car there is a BIG sticker with the tyre pressure for 17's on it!

Could i find it today, in the rain - at the garage - Hell no!

Anyway, the handbook does not list 17's

I took a stab at 29lbs front ant 27lbs rears.

Can someone let me know.

I ran mine higher than that. 32ish, sometimes a bit more. I found that it handled much better with the tyres firmed up and I was less worried about damaging the rims on potholes!

Also do a search on "Tyre Pressure", you'l find many have set thesres between 32 and 36

I used to run my 16's at 28/29. Had really quick wear and upon changing them was told that I had been running them under-inflated, as shown by the wear pattern. Now running at 34, which hasn't comprimised handling or comfort, but has improved the wear on the tread.

there should be a tyre presure guide on the driver's side door-post,just bellow the door catch?
i put 30-32 in my 17'z,all four have very even wear on them and they have done about 18K miles,the front's have a few mm less than the rear but still highly legal
also ive never swap front to rear,i like to buy my tyre's a pair at a time :rolleyes5

The sticker you're after is on the driver side B pillar, just below the door catch.

It's 2.2 Bar for the fronts and 2.0 Bar for the rears.

For high speed driving, increase pressure to 2.3 Bar front and 2.1 Bar rear. :)

Don't forget that this is not the VR-4, so is several hundred kilos lighter!

i put 33psi in the front and 29 in the rear ( i like the back end a bit looser, old hadits and all that) and havent had a problem yet, even wear and good grip and ride

I think your find it is more like 100 kg difference

This 2.4 Viento (http://english.auto.vl.ru/catalog/16088/) weighs 1370 kg so I suspect the V6 will be about the same.

And the Type V (http://english.auto.vl.ru/catalog/16142/) weighs 1480 kg and the Type S weighs only 40 kg more.

Errr.......Not Quite.


The 2.4GDI is a fairly heavy block, despite being a 4 cylinder... It's build heavy to withstand the compression. Don't forget also that the Viento is an automatic. I think the V6 we're talking about is a manual, which is a fairly lithe 1315/1320 kilos depending on accessories.

Obviously the Auto V6 is more, but generally there's some 200 kilos between the V6 Sport and the Type-S.

Ahh .. Well the extra 100kg is probably going in the rear to support the 4WD, AYC, etc. Which most will agree is well worth it.

Also with the 100kg on the rear, the weight over each tyre would be about 50 kg each on a VR-4, so back to the point of tyre pressures, it could proably be set a little less than what you put in a VR-4 or 17's.

I queried this fact with my dealer when I had my V6 Sport Legum serviced as the owners handbook refers to 16" wheels. He gave me the figures of 32 Front and 30 rear for 215/45/17 tyres. It seems to be working for me as I am getting even wear and about 36000 out of a set of Dunlops.

32 front 30 rear is what Dunlop told me for 215/45/17 on my V6 Sport as well, they lasted about 20000. I'm now on Uniroyals, they seem OK tto but I got them for £75 each (wholesale) - bargain.

With the W+ tires you guys are sporting.. I dont know how you fellas run so under inflated... it will just cause excessive wear especially at the speeds I keep seeing you guys post about. (Don't you guys ever look at the sidewall for the tire's rating?)
I run 38's and 44's for good roads and spirited drives. No tire shop I have been to in 2 countries have ever recommended less than 36 either.. and that was for really bad roads.

Inflate to 40/40 or 40/38. Make it 44+/44+ on trackdays. Just look at the recommended psi on your tire's sidewall.
You can think of it like this: if you're hitting a curb with 16" @ 34 psi, that is not NOT the same as hitting the same curb on 17" @ 34psi. The lower profile the tire, the more air you will need to back it up (exponentially higher). Because that is all the support a tire has with smaller sidewalls. Air.

i dont know who started it but who said you should run your tyres harder on the track? when i was racing bikes we used to run the tyres softer so once up to temp the presure was right , this works a lot better on the track than the road coz the tyres are working a lot harder. just another little nugget of info while i'm on one ,did you know that road tyres get up to temp faster than a set of slicks

You are right at temperature, after a lap or so on a track the tires shouldn't be higher than 44 or 46. An increase of about 15% over cold. The only variable I was thinking about at the time was steering response and flex. So, when cold, 38/36 should do it.
