I have excessive tyre wear on my front tyres on the inside and feathering also.

Alignment is around 2.2 and zero toe. And tyres are Michelin PS3 225/40/18.

Pressure has always been around 36psi

Inside is measuring about 3mm and outside is 7mm.

And alignment was last done 6-8 months ago.

Car is a JZX100 with BC BR Coilovers and Cusco swaybar. And everything else is stock.

And this is what the tyres looked like 2,000kms ago. Quite fresh 7mm all round. Sorry for the horrible photo

Ive had similar alignments before and accept the fact with this setup this is how the tyre will wear, but they did not wear this fast!

Looking to see what i should start looking into first,

  1. Upper and lower ball joint?
  2. Lower coilover bushing 
  3. Redo my front alignment

I dont feel much play or have any shake in my alignment either.

 

Any input is great, my car is a tyre killer!

Pry at the upper A arm bushes. If they're worn, the wheels can tend to toe out under acceleration.

My car is doing exactly the same thing.

 

Shockworks coilovers

upgraded swaybars and links

TRD LCA bushes

Superpro rack bushes

Superpro castor bushes

Replaced upper arms 2 or so years ago

1 year old lower ball joints

Newish tie rod ends

 

For the life of me cannot get an alignment that will stick, its almost like the alignment becomes worse over time.

Hmmm will a worn caster arm bushing cause play in my alignment when driving?

I definitely can see that the tyre is getting some toe treatment, but im not expert.

 

Didnt feel much play in the tie rods or lower or upper ball joints. Maybe ill give it to an expert.

 

So options are,

- adjustable castor rods

- X110 castor rods

- replacement bushes for existing rods

For your car @FragLord did you previously get an alignment and ? months later get your alignment rechecked and it was out of spec?

How bad are your front tyres wearing out?

Yep I had one done in March just before the track day, car recently started pulling left and found toe was out of spec even though I have not hit anything or touched anything with the suspension at all.

 

Insides basically the same as your's. They are inspecting inner tie rods today to see if they could be a problem.

So back to this. I had the castor bushes replaced and the an alignment redone. 

When it was inspected there was over 6mm of toe out.

It was all dialed back to 0 and was all fixed.

 

And 6 months down the track i have the same issue again...

I kept having the same issue over and over again, toe would suddenly appear more and more over time and the alignment kept going to shit

What bushes did you use? I changed mine for superpro bushes a few years ago and no issues since. The only issue I had was toe out when I chucked in the new shocks. Was contemplating getting a/m option but its a street car so decided against it.

I went with TRD bushes. Im now thinking to look at getting the inner and outer tie rods changed if i can see any play in the adjustment once i jack it up.

Any thoughts or ideas would be helpful. Looking to have to get new front tyres again soon.
