What causes severe wear on the inside of the front tyres

[B-Man]

On the Gloria, the front tyres are worn to the belt on the very inside if the tyres - only about like 2cm - it's like someone has filed the corner of the tyre on the inside.

The rest of the tyres are fine - good even - it's only the very far inside corner of the tyre.

The rears are fine.

Yes the car has been lowered.

i could be few things mate, struts,shockies ect ect may need a wheel alighment id take it to a suspension place or tyre place they should soon find the problem.

Not sure what the suspension on the Gloria is or like but when lowering some cars cause excessive camber. Either that or excessive toe out, I think?

yeah, probably a toe problem, get a wheel alingnment. I think inside wear is toe in tho, not toe out. Either way you should be looking for 0 toe.

a camber kit should fix that ?

normal for skyline to have tyres worn first on the inside.

would have thought it was camber... mine did the samething... when i can be bothered i think i'll get a wheel alignment

Camber, Toe In, Tow Out - ya da ya da - I have know idea what all this stuff is -

I know that camber is when the wheels look really phat cause they are fully on an angle bro - so you can go round corners faster.

I reckon it has something to do with the fact that the car is lowered - I sketched it out , with the force lines and stuff.

I'll take it to a suspension place after I get rego - Not sure that a wheel alignment will fix this - the wear is fully severe. They will prolly ping me for the tyres when it goes in for a blury tomorrow - but that's cool, I'll get some new tyres and then take it to a suspension place.

Unless, the wheels and tyres are off another car that had a problem - maybe there is nothing wrong - Anyway I'll tak it to the experts.

I thought there might be an easy/quick way to tell if there was something wrong -

When I looked underneath there wasn't anything broken !

Cheers for the help !

Toe is the difference in distance between the front and rear of the tyres. Historically front toe was the only thing that could be modified as rear wheel drive vehicles using a rigid axle had fixed rear toe, usually neutral. Many modern front wheel drives have rear toe adjustment as standard which is critical to their handling.

Current VT Commodores have an independent rear suspension design that has substantial dynamic toe change requiring after market solutions to correct. Whiteline IRS Camber/Toe adjusting kit is designed to around this problem. Essential when lowering. (See IRS for more details)

Excessive amounts of either will adversely effect tyre wear.

Excessive toe-in makes the car unresponsive and doughy.

Excessive toe-out makes the car nervous and lacking in directional stability.

Minor values are useful for improving turn-in, steering response and masking torque steer.

Excessive wear on the inside is probably 1 of 3 things Brendan:

1. Excessive negative camber. i.e. The bottom of the wheel sits out further than the top of the wheel. (the "phat cause they are fully on an angle bro " of which you speak ) or,

2. Excessive toe out. i.e. the front of the wheels are further away from the centreline of the car than the rear of the wheels. They "point out" like each wheel is turning in a different direction. However, the amount of toe out required to do this would make the car very twitchy.

3. The tyres were worn on the outside and swapped over on the rims to hide the problem.

I'd go with 3 or 1.

bad toe setting?? 0 toe as duncan said

[B-Man]

I put new Yokos in it last night - so when it's regeistered, I'll go get my toes adjusted.

Thanks for all the help !

maybe your tyres have not been inflated to the correct pressures, and have always been kepted at the wrong pressure level.
