Rear Tyre Consumption?

[Stealthdave]

£35 I half didn't mind, but new tyres as well? No chance as I still don't think I've seen a thread we're anyone has had new tyres on long enough to know that the problem is definately cured...

Anyone had any luck getting this resolved at either willoughby's at nottingham or gk in derby?

Back to the rear tyre wear issue:

As I advised back in September - new tyres and a camber adjustment at the rear was effected. 4,000 miles in and my tyre dealer is checking for wear - so far so good. Using assymetric Goodyear F1's so problem - could be solved??? Tyres rechecked yesterday at tyre dealer A and A Tyres - Cardiff. 8mms on each side of rears inside/outside edges.

Maybe???

Out of interest - do you know what values your camber was adjusted to? A service is due (and new tyres on the front - Boo!), but I'm thinking of having the back wheels stood up a little so I don't destroy any new tyres I put on the rears... Thanks!

 

[MIKE THOMPSON]

Camber angles: haven't got the details at the moment but will post them later.I'd suggest going to a good tyre dealer with Laser - 4 wheel alignment equipment. My tyre dealer took a chassis number from the boot floor to obtain the settings on their software and then adjusted from there. Most dealers I guess won't have the specialist equipment.

I will provide details later today from the print out supplied before and after alignment. Look for my post later today.

Thanks Mike. I misunderstood you slightly - I thought you'd gone 'off-spec' with the wheel alignment to draw the wheels in slightly at the bottom - to reduce the factory camber setting.
I had a 4 wheel laser alignment recently (which found that one of my wheels was toe out) but as the camber on the sports suspension is quite acute, I though I might straighten them up a little so the wheels run on the flat of the tyre, rather than just the inside edge... Does that make sense???
Cheers!

(I'm still interesting in the details of your print out though...)

 

[MIKE THOMPSON]

Lil,

Here are the settings for your rear suspension / tyres - camber angles still within cupra spec (Camber angles)

- 1.20 degrees now
- 1.35 degrees before

Cheers Mike

How good would new tyres be?

Thing is I have a service end of december, but have just been unlucky enough to have a puncture that couldn't be repaired on the rear. Will have done approx 1800 miles before it goes for service? Would I be better to take it now and get the alignment sorted or just wait till the service, let them sort the alignment and then get the other rear tyre swapped?

Cheers

 

[Stealthdave]

Mike,

Does those settings apply to the stylance with the sports pack too?

I had to have 2 new rears on my mk2 leon fr at 20k service. It's going for its 40k though near xmas and there's still plenty of tread left on, so god knows what the guy who had it for the first 10l miles did to it, lol! Front last about 10k.

 

[Stealthdave]

I just want to get it sorted now, it's really ruining my enjoyment of the car...

In comparison, we also have a mini cooper running on 17s, and although there is road noise, it's constant rather than the whirring sound the leon seems to give off on certain types of road surface...

Just booked it in for 24th. Spoek to head technician in service and he said he wasn't aware of any issues, but they will have a look...

Sorry, forgot to mention, when I had my rear tyres replaced, that was due to un-even wear - needed laser wheel re-alignment (apparently) and the *******s wouldn't do it on warranty!!!

 

[MIKE THOMPSON]

You need to check with a competent tyre shop the FR has the cupra suspension and the camber angles can be adjusted - the issue about the sub frame raised elsewhere is not true. If the stylance has sports suspension I guess the same rules apply - a good laser shop will check the codes in the boot under the carpet - then go from there.
The figures quoted on 26/10 are from my print out.Work was done at A and A Tyres Cardiff (very helpful) - there have been similar issues with Honda Typre R and Mazda MX5 .
Solution is to sit the tyres up marginally.
A and A are confident now sorted - just fyi my tyres were sent to Bridgestone and they quoted camber wear but no allowance.See my earlier posts for the story.
Good luck.

It IS a warranty issue - name and shame the dealership - had both ours done FOC and one was miles out!!, still trying toget a % back for tyre wear. ...........................hoping!!

 

[lil_pidge]

Stealthdave - I'll post the figures I was given for my Stylance with Sports Suspension soon when I get chance (V busy at the mo!). Need to find the docs again...
My rear tyres still have plenty of tread (done 22k now), but when I come to replace them, I will 'stand them up' a bit so that I don't get the road noise on the next set (hopefully!).
Definately worth getting the alignment checked by an independant!!!

 

[Stealthdave]

cheers bud...

It's goign in for SEAT to have a look at next Monday.

If they are no help I'll take it to somewhere for the re-allignment and a 2nd new back tyre.

Out of interest, is it the camber at fault or just the alignment?

I have a Hi-Q closeby, anyone used these to get the tracking sorted?

This was Hobins of Preston. They're a nightmare when it comes to warranty issues!

Right, here are the suspension setup details for a Leon Stylance with Sports Suspension - according to Tyres and Exhausts Galore in Leicester (who I found to be very helpful and knowledgeable).

(All measurements are in degrees and minutes)

Front (Left and Right)...
Toe: Min 0° 00’ Max 0° 10’
Camber: Min -1° 11’ Max -0° 11’

Rear (Left and Right)…
Toe: Min -0° 00’ Max 0° 10’
Camber: Min -1° 50’ Max -0° 50’

Front Ride Height (Left and Right)…
Min 363mm
Max 383mm

Rear Ride Height (Left and Right)…
Min 365mm
Max 385mm

The problem with my car was due to the toe setting at the rear (i.e. the rear wheels were ‘boss eyed’).

If you can imagine an x, y, z axis – where x is the direction in which a car travels forward and backwards (toe), y is perpendicular to the direction of travel (i.e. imagine a fixed axel between the rear wheels) and z is going directly up the side of your wheels (camber) - apologies if this is patronising!! My car had a bad setup in the x axis (toe), so the rear wheels were pulling away from each other, therefore scrubbing the tyres.

Because of the z axis (the camber) they only scrubbed on the inside edge of the wheel.

I had my toe adjusted so that both the back wheels are now pointing in the same direction! When I come to replace my rear tyres, I will adjust the camber to the minimum limits (i.e. – 50 minutes {= -0.8 degrees}), which will stand the wheels as upright as the tolerances suggest I should. This should make the car run on as much of the rear tyre as possible, and not just the inside edge of the tyre.

I hope this makes sense, if not let me know and I’ll try to explain further. Apologies if all of the above is very patronising!

I'm going for a beer now!

Cheers,

Will.

Glad to hear your alignment is now sorted - guess you should keep your rear tyres within the spec parameters when you get the new tyres.
Hopefully, you can now enjoy your motoring.

Lil Pidge,

Can you PM me your chassis number as the specs are completely wrong!!

Were they using approved Beisbarth appliance with latest ELSA 3.6 update.

For instance a Leon 06> with Sports running gear PR G50/51 should have a rear camber spec of -1*20' +/- 30' and not:

Camber: Min -1° 50’ Max -0° 50’

Please don't use the figures quoted above for every vehicle as there are 5 different sets of specs depending on your PR codes.

Kind regards.

I got 33000 miles before I had to change my rear tyres
