mpgscott 0 Posted February 3, 2009 Report Share Posted February 3, 2009 Well i fitted new tyres today onto my RS8 alloys, have fitted 205/40/17's and there is no rubbing feels fine.Big problem is the old wheels i took off, there were fitted with new toyo proxies only around 1900 miles ago. Today when they came off there is extreme wear on the insides of both tyres more so on one side to the point its through to the wire. This would explain why the car feels so loose at the front and wanting to slide as there is hardly any tread left.Now the car had coilovers fitted before i got it so i am thinking that they have never had the camber adjusted. Also its not the alignment as the car does not pull to any side it feels fine only that it wants to slide in the wet. With the new tyres it feels fine but at the rate they have worn out i need to get this sorted out.So i am thinking full wheel alignment incl camber and tracking.Any other thoughts.Also when the wheels were being put on the guy informed me that there is a hole behind the front wheel so thats going to need done. Any areas prone to rot on the front behind the wheel?? Going in for Mot on Thursday so will have to see how it goes. Link to post Share on other sites
ip 0 Posted February 3, 2009 Report Share Posted February 3, 2009 If you have extremely toe'd in steering (both wheels pointing in too much) plus a bit of negative camber you may not notice any pull when driving/accelerating but you will notice a little bit of extra understear and more than average tyre wear on the insides of the wheels.Also, if the coilies are set too low (wishbones sit below horizontal) then you may also get unpredictable handing and tyre wear. The Mk3 benefits from a little stiffening up of the shocks but doesn't like to ride too low!ip Link to post Share on other sites
binliner 0 Posted February 3, 2009 Report Share Posted February 3, 2009 Yep, full alignment set up is the place to start, that's the most likely cause... worn bushes could also be the problem but get the alignment checked first Link to post Share on other sites
mpgscott 0 Posted February 3, 2009 Author Report Share Posted February 3, 2009 Yeh looking at the car its obvious there is a problem. If i set the drivers wheel straight and then look at the passenger wheel its pointing out to the left instead of straight. Also i put a spirit level on the drivers and passenger wheel and the drivers wheel seems out slightly more at the top than the passenger on.So car is going in for Mot so i will get them to do the alignment at the same time. Could simply the tracking cause this?? Link to post Share on other sites
spindat45 0 Posted February 3, 2009 Report Share Posted February 3, 2009 Excessive toe out (wheels pointing outwards as you described) which is tracking and excessive negative camber (top of wheels pointing inwards) will cause that sort of wear. Both will need checking and adjusting. Toe in by itself usually causes wear to the outer edges of the tyres. As you said in your first post the camber and tracking probably weren't done after the coilies were fitted. Check with whoever does the alignment that they can do lowered cars as some older equipment can't fit under the arches if it's too low.As for the hole behind the front wheel, some pics would help as that's not somewhere I'd expect to see excesive rust or a hole unless it's meant to be there :S Kevin Link to post Share on other sites
mpgscott 0 Posted February 3, 2009 Author Report Share Posted February 3, 2009 Here is a pic of what they are talking about.Its just behind the passenger wheel and does look like it should be there with some sort of gromit on it. Link to post Share on other sites
