Uneven tyre wear on my S2000
garyo - 5/3/13 at 08:05 PM
Hi Chaps,
My S2000 has some strange tyre wear on the inside edge of the front right (off side) tyre. The other front tyre has no issues, so in my mind it
can't be tracking related (the car drives and brakes straight and true) so I *think* it must be a simple case of too much negative camber on that
wheel...
I'm no expert though, so thought the wear may be a dead giveaway for someone that knows.... particularly the lip on the extreme outer?
I'm broken hearted at having written off a brand new tyre in what feels like only 5000 miles!!
Cheers!
Gary

I would certainly have a 4 wheel alignment check done as soon as the new tyre is fitted or the same will happen again!

it hasnt had a knock on that side has it nephesw escord did and the bottom hub was bent. it may also be down knackere bushes on the wishbone

Wouldn't negative camber be wear on the inner edge?

Deffo looks like negative camber, I had the same on my car.

Yep - it's the inner edge that has the wear.
I suspect it must have had a knock - the lower wishbone is adjustable but is already on the limit of the direct I'd need it to go in, so I
suspect a bent upper wishbone and the previous owner has tried to dial it all out as best they could.... I'll wheel it in to the garage this
weekend and measure the camber on both sides to see what's what.

Feathering (what you call a lip) indicates a toe problem rather than camber issue, normal width radial tyres are pretty tolerant of camber
issues.
The feathering rather than plain edge wear is caused by the tyre running with a slip angle pulling the tread sideways.
Simple check over of all the ball joints and bushes band checking the toe accross the axle.

Mmm interesting - so that would imply too much toe in on just that one wheel?

which surly you would notice under braking or turning response difference from left to right.

You can't have toe in on one wheel, it is measured across the axle.

Got many roundabouts where you live? Ive had this before. It was down to bad camber and too many roundabouts. I would be checking suspension too.

Indeed, unless there's an opposing problem on the rear axle that means the 'dynamic' toe position means I'm always driving the car
with the nearside wheel pointing forwards, and offside wheel with too much toe, and then something at the back of the car causing crabbing. Both rear
tyres look perfect, although I've not examined them closely for and fine feathering. I'll take a look tonight.
The car brakes, tracks, and corners beautifully. I'll measure up this weekend and see what I can see.

Strangely it's the off side wheel rather than near side, which would be the usual one to take a beating from roundabouts. I do around 50% of my
miles on the motorway though, and don't really hoon it around roundabouts particularly.

I get similar wear on all 4 tyres on my tin top despite two totally independent 4 wheel alignment lol.set of tyres lasts no more than 12k. Could it
not be a castor issue?

On mine, the outside of the NS tire and inside of the OS Tyre wore when hooning, but the inside OS tyre was definitely worse off.
