Uneven wear on tyres

vicwatson

I seem to be forever getting tracking done and new tyres

Two of them are wearing unevenly, front nearside wearing on outside, and rear offside is wearing unevenly on the inside

What is the reason for this? The offside rear inside wearing has happened me before, got new tyre and tracking done and it's back the same way again

Coincidentally both of the mentioned tyres have slow punctures, at least I think it's just a coincidence.

Cheers for any advice

How long ago did you get tracking done if it was a couple of months back it could be well off again a big bump or pot whole can take trackin off 5 mins after leaving garage...some mechanics dont even do trackin down my way because it can go unaligned so quick so it wont hurt to cheak it again if its not that then cheak top and bottom ball joints..bushes etc.... and make sure tyres are the same psi if not it can feel like trackin is of and tyres will wear quicker....

First get the punctures fixed. A tyre running low will wear all wrong.
Second, get full wheel alignment with full printout.
This will show what is actually going on. It will show if there are aspects of the setup still out of tolerance once basic alignment has been completed.
It is possible you have worn or bent suspension or some other issue. As I say, a full report show give a good idea where the issue is if there is in fact an issue.

By tracking garages often understand only setting front wheel toe, nothing else.

Make sure you get your suspension checked for any loose bushing, ball joints, etc.
Once you're sure everything is fine, have a proper 4 wheel allignment which would include reading of toe, camber and caster.

In many cars setting toe on rear axle or camber on both axles is not as simple as adjusting with a screw, but requires extra parts and sometimes it's impossible at all.


To me, it looks like you have either some loose parts in your suspension or incorrect wheel alignment or both.

The two tyres need replacing so will do that. Should I then have the tracking done all at once?

There is more to uneven tyre wear than just the tracking being out.

Yeh that's why I made this thread. What do I need to be checking?

First - any loose parts in your suspension.
Second - proper 4 wheel alignment.

Now that I think of it, the rear wheels look slightly splayed. Had mech look at this before and they said there was nothing amiss

Would I be better off getting the two new tyres put onto the driving wheels I.e. The front two wheels? Or rear two?

I'd put them on the front seeing as they are the first to meet standing water, do all the steering, accelerating and alot of the braking.
The tyre industry recommend putting best tyres to rear because they believe that the rear end losing grip is more dangerous than the front.

Because it is more dangerous.
Considering vast majority of drivers have absolutely no clue how to recover from rear end skid, and still most cars on Irish roads have no esp, then putting better tyres on the rear is indeed safer option.

Only case where it's safer to put better tyres in the front is on car with esp or with driver higly trained to control skids.

I got a full 4 wheel alignment done with Tom McElarney in Dundalk over a year ago after I swapped out the tie rod ends on my 740. The rears had pretty diabolical side wear, which he assured me would be rectified after the alignment and a new set of Continentals. After the alignment the steering wheel was well off center, had to go back and have the whole lot repeated a few days later which was a right pain.

I couldn't help but notice there was a lot of red numbers on the print out after the re-do, but I assumed he knew what he was at as he's supposedly one of the best. Shooting ahead 12 months and there's now exactly the same outer wear on the rears, which would probably last a bit longer were it not for the unevenness.

The suspension is rock solid and was up on a ramp for a full prod and poke of all components not so long ago. My pressures are always spot on too. I'm so sick of dealing with wheel related trades here, I have nothing but bad experiences.

I rapidly wore the outside of the front left tyre on a Ford Ka many years ago.

The cure was to change my style of entering roundabouts.

Well lads and lassies, anyone able to decipher this jargon for me (and does it correlate with "Two of them are wearing unevenly, front nearside wearing on outside, and rear offside is wearing unevenly on the inside")

Sure what would they know...

I've had countless 4 wheel alignments done over the years and the only place that has done it well for me is TAB (Tyres and Batteries) just off the Naas road near woodies.

A wheel alignment is only as good as the person doing it.

So can anyone decipher my results into simple English ?
