tyres

[STEVE S]

Hi I need some help I have a 2004 manual 3.2 GSi I am using 225/45/17 Y91Goodyear GSD 3 running 39 PSI front 35psi rear

I have a couple of questions:-

1)the fronts tyres have only lasted 11 months and 9000 miles the near side front seem to have worn on the inside edge more and in the centre more looks to be over inflated. Also that wheel is droning a lot sound like a wheel bearing. The handling seem terrible now I am hoping its just the tyres.

2)Should I be using extra load tyres my manual does not state?

3) The rear tyres seem fine no problems, but if you grap the top of the wheel you can feel some very slight movement as if the wheel bolts are loose. When you jack the car up if can’t seem to find the movement.

Sounds like a bearing has caused premature wear, especially with the wobble you describe. I get over 20k out of my fronts and I cane them. Easy to have your bearing checked BTW.

How do you check the bearings mate?

jack the car up and give the wheels a pull from top to bottom and side to side, basically be rough with the wheels (by hand). If they rattle around then either the bearing has gone, part of the suspension had gone, or the bolts are loose.

I'd recommend trying the XL version, 94W
However, they are rock hard compared to the standard version 91Y

It should be noted I have just sent a pair of Good Year GSD3 tyres back for inspection, as the inside edges of both tyres had clear signs of defects which I suspect have been caused by the Vectra itself

Having trawled 100's of threads on the forum today on bearings, I seem to remember that GSi3.2 said you can't check the bearings the "old fashioned" way. The Haynes manual makes no mention of checking for play in the front bearings and TIS 2000 says you have to use a guage to check for run out and play.

Steve S - I've got the droning as well that started recently, see http://www.vectra-c.com/forum/showthread.php?t=62794. New tyres haven't stopped it. There's no mention anywhere as far as I can tell of the GSi needing XL tyres. Indeed I've gone for 91W today cos I don't want the harshness of XL's. So it looks like bearings or, and no ones mentioned this yet, driveshafts?

No need for XL tyres on the 3.2

No, but they are slightly cheaper than the standard version
I also noticed that they last slightly longer too, based on wear rate over the last three sets of tyres

[STEVE S]

ok does the wear on the nearside front tyre sound normal and why does the manual state what load rating my tyres should be i belive my vectra b gsi stated the use of xl tyres.


Lastly checking the rear suspension is this normal:-

The rear tyres seem fine no problems, but if you grap the top of the wheel you can feel some very slight movement as if the wheel bolts are loose. When you jack the car up if can’t seem to find the movement.
