Inside wear on 19s

[Golfpro]

Hi Guys,

just back from the MOT and the car passed as usual:)

 

However, the examiner pointed out that the front tyres were badly worn on the inside edge. The inside inch and a half was virtually slick while the rest of the tyre had 5 or 6 mm left.

 

My car is running 245/35/19 Goodyear Eagle Assymetric fronts with Tein Superstreets, TRD sway bars and R2 poly bushes. Front geo is 0 toe and -0.50 camber.

 

I know that larger wheels on lowered suspension is not ideal for tyre wear.

 

The car drives handles nicely and I have got about 12k miles out of the fronts.

 

Maybe this is as good as I can expect given the setup but it is a bit annoying that I am going to have to change the tyres when there is still plenty of tread on 90% of the tyre.

12k miles isn't all that bad with 19's. Maybe next time buy non directional tyre's and rotate them at 6k.

[TLicense]

Actually ignore that, was thinking of the rears!

 

The camber is probably about there or there abouts.

I assume that is is unwise to reduce the camber any lower?

I have exactly the same problem, it is going in to get a full geo set up soon to try and ease the wear on the fronts.

had the same problem, when iwas underneath the car taking the turbos off i wondered what was jabbing me in the shoulder, was the wire from the inside shoulder of the front tyres. I had my geo set up with the lance alignment (which sorted a load of problems btw) but i think its just hard cornering that rubbed mine out, heavy engine to get to change direction. Cant remember what the camber was set to but it was as-per the lance alignment.

Im very supprised you have 5-6 mm of tread left on the rest of the tyre with 1.5" slick on the inside with

the set up you have, especially if they've done 12,000 miles

 

Mine is lowered on Eibachs with 265 fronts on 19" rims and the wear is progresively more to the inside edge but

nothing as pronounced as yours, my set up is -1 degree of camber and +7 mins of total toe

Get the front toe checked, very critical to tyre wear if it's even slightly out.

[Chris Wilson]

Try it at zero camber, it may help, but the suspension isn't designed for wide ultra low profile tyres, and if it's lowered at all it will be even worse. You should be able to get fairly even wear (yours sounds terrible), but at a cost to ultimate front end grip. If the bushes in the front wishbones are less than perfect you are wasting your time though.

Bushes should be fine as all were changed to the poly bushes three years ago.

 

I would rather I had to change the tyres every 10k (I only do 5k per year as a daily driver) than compromise the handling.

 

I notice from the Lance settings that his front camber is -1.0 so mine at 0.50 is possibly less than optimal at present.

[Golfpro]

Typo on last: should have read -0.50 not 0.50.

Just an afterthought, as 90% of my driving is in slow moving city traffic could this cause the inner side wear?

 

If I was driving more vigorously into corners the car would be pushing into the mid and outer section of the tyre therefore utilising the camber.

 

But because I am driving into parking spaces and in and out of lanes I am putting more full lock on which probably stresses the edges of the tyre?

For the record, cornering wear should rub off the outside of the tyre. If you're doing a great deal of cornering and your insides are still bearing the brunt of the damage, your camber is far too high. Driving in a straight line on cambered tyres wears the inner edge, cornering on zero-cambered tyres will wear the out edges. The camber is used so that the tyre sits flat (with a little conicalisation) in the twisties.

 

Possibly the suspension is too soft and is picking up too much extra camber once loaded?
