David, Ok,
So why are our local council now making changes to speed calming humps, because according to the new civil engineers, the original ones were not to required specification?
Or are they changing them because the local bus companies refuse to continue to use the routes?
or has the latter prompted them into making the changes?
Wes.

Wes.
interesting, any road surface which is not deemed to be private, which could cause damage to the tyre would bring a claim against the local council in that area.
Speed humps are designed to slow vehicles down, mostly in streets were children play, now we had this conversation at work some time ago when the workshop staff advised that speed humps break coil springs, sorry totally disagree, driver dis -respect for the built up area driving too fast breaks coil springs, not speed humps.

Mondeo mk1, I changed both lower arms, both front shocks,bearings are fine, decided to change both wheels because both sides were wearing on the out side, This time the nearside(pictured) has worn away, i marked with little white lines, really worn quickly (just a hundred mile or so). As i understand it the camber cant be adjusted on the mk1 mondeo.
So whats my problem is it tracking ?
Any help please.
The pictures of your tyres appear to be part worn and not new. Normally shoulder wear on the outer edges is caused by tow out on turns being incorrect, Ie Tracking, but can also be caused by driver habits, eg, high speed cornering, heavy loads carried in vehicle etc. If the tracking has been checked, it could still be out of tolerance if the personnel did not ensure that any steering pivot points, inner or outer track rods ball pins, ball joints, bushes etc are not within recommended specifications.
We recently had a vehicle in for mot test, the offside outer track rod had in excess of 05mm free play in it, the customer pointed out that there could not be any play in it because the tracking had only just been set?
The personnel who did the tracking rang us and said the same, how can you say that the track rod had excessive play?
If garage personnel who do servicing work on behalf of customers don't stay within the manufacturer guidlines when adjustments are made, how can the job be correct for the customer?

Ha Ha! David, GOTCHA!...........LOL!
Toe In, can produce Wear on Outside of Tyres! Toe Out, can produce Wear on Inside of Tyres.
The Design of some One Way Road systems in some Towns, If Directional Will result in Abnormal Tyre Wear!
If Clockwise Like Most, then The Nearside Front Tyre, Will "Suffer"!
This Guy, Has Already Stated, that A Complete replacement of all relevant parts Have been replaced, and tracking Has been Done.
As Previously posted, A Full Explanation of "The Issue" Should be Fully Explained to the "Wheel Alignment Guys".
Just Had a peek at a Photo, From this it appears to me that, The Tyres Are Running "Underinflated" as Both Outer Edges are Wearing?
So, Now Looking, and Not "Ass u me ing", Could this be a Simple case of "underinflation"?
ps; Are The "White" "Highligted Areas" Within "The Area" In "The Manual`s Description" or Are "We" In Another "Grey" area?

Something tells me that not all roads in the UK are good roads, however, under normal everday thinking, highways engineers are supposed to taper the camber of the road towards the pavements from the centre to permit rain water to drain away, this prevents a build up or film of water being created at the front of a vehicle tyre, which in turn prevents aquaplaining. When vehicle manaufacturers design the front suspension geometry, tolerances are designed so as to allow for the road camber.
Granted over the years many problems have been present, but modern vehicles are designed on a scientific basis, and not a individual persons ideas of view points.

More than "just a hundred mile or so"used on that tyre.When using worn tyres you cannot tell by "looking" at treadwear what the problem is...Take ye car in for a Geometry check... will cost ££ but at least YOU will know whats wrong with your Motor........Last edited on Sat Aug 30th, 2008 12:18 am by big..E.

It seems to me you should go for the full geometry check, might cost a few quid but if your tyres are wearing out after 100 miles or so, then it would pay in the long term.
We use "Hunter" Pro Align, try to find an outlet near you with this or similar kit. Have a look, http://www.alignmycar.co.uk
ps; explain to them the full history of the issue beforehand.

Ive had this car 4 years now and i have always had the same problem with the front tyres always wearing more on the outside edges, I had the tracking done at a garage because the steering wheel was off centre, All they did was a few turns of the track rod ends, they used a scuff plate ?
The strange thing was that i changed the front tryes only a hundred miles ago yet the nearside has worn very very quickly. So because i changed both tyres the tracking would be out ?.
After changing both tyres the steering wheel was off centre again, Is this normal ?
Is there any easy way of doing the tracking myself or should i take it to a garage, Or maybe i should go for a geometry check. I replaced all the front end, New shocks, new lower arms, anti roll bar links, recon power steering rack, this was done six months ago.
The engine clutch not been touched and the subframe looks to be fine, good mounting rubbers
Maybe its a mondeo mk1 fault, but it would be nice to sort it out,
thank all

If i change the track control arms on any car, I always check the tracking afterwards. More often than not, the tracking will be out, even if it was ok before the arms were replaced.
Have you changed the clutch recently?? The engine subframe has to be removed, if it's not replaced exactly right, it can cause wierd tyre wear.

Hi,
Looks like is a traking problem.
if you rub the palm of your hand over the outer tread part of the tyre, does it feel smooth one way and rough the other way?
my guess is its tracking problem, and its toeing in.
Easily fixed.
