Is it possible for a tyre to develop a pull? - fendertele

If the driver needs to hold the steering wheel off centre to keep the car going straight all the time.. which is basically toeing the car out slightly the opposite way from the pull would the tyres develop a pull in the direction the car is being tied out too?

Due to the camber of the road, cars tend to pull to the left (in this country). This necessitates a slight steering input to the right. This means the front tyres (and to a lesser degree the rears) tend to wear the left side more. The tyres will effectively wear into a cone with the apex on the left hand side. If you roll a cone, it will perform a circle. Tyres that are left on the same position will therefore make the car pull to the left. This can be corrected by swapping the front wheels occasionally (but don't do it just before driving abroad, as I once discovered) and only if the tyres aren't 'directional'.

Pothole damage to the steering/suspension will make a car steer more one way than the other.

Reason I asked is my car despite being aligned.. the caster is the wrong way round despite being green on the printout I was told my passenger front sits further back than the drivers front causing it to pull left constantly.. so I drive around holding the steering at the 1/2 o'clock position..

For the first couple of hundred miles the pull was always to the left however there is also what feels like a slight pull also to the right now causing me to constantly recorrect both ways and always need to turn the steering wheel left..right...left right to keep the car straight.

So I had thought maybe it was due to how the tyres were wearing in.

I don't think any car with correctly set-up steering should do what you describe here, unless the steering assistance is very vague, or something is worn somewhere.

I remember travelling to the Canadian Rockies in about 1964 in an elderly well-worn Beetle (which of course had a rear engine) and the car performed a continuous gentle sine-wave along the road which it was very hard to stop oneself correcting - which was a waste of effort.

When a car is aligned properly, all 12 axes not just toe-in, it'll hold straight on with no hands even on the camber - and the tyres will wear evenly across the tread if the correct pressures are used.

The car is aligned on paper everything in the green however after speaking to someone at Hunter my caster values are supposedly the wrong way round and upon inspection my front passengers wheel sits further back than the drivers front wheel which is the source of the pull left.

This issue will be resolved in the coming months however I was just curious about the tyre wear thing for my own sanity as at first there was the expected pull left but following a couple of hundred miles of driving there is a strange pull also the right when I correct the pull to the left causing me to always be adjusting the steering left..right left... Right to track straight

Is it meant to be like that, or has something been bent somewhere?

I wouldn't imagine so, I'd have thought both wheels should sit evenly between wheel arches.. the car was delivered to me like this new so it's being investigated to repair or return just waiting for the decision.

Something about loosening subframe can reset it

Unless it has an adjustable mounting I would have thought its more likely the subframe is twisted which would make more sense imo

Poor or negative caster will ruin the natural self centreing of the steering wheels...ie try to push a tea trolley but keep its caster wheels the wrong way round, its impossible.

I'm rather surprised they could give any of the various alignments a green light if something as important as the caster is wrong, and something as obvious as one wheel being further back in the wing would suggest the caster is out by a large amount on that side.

As to what caused it is anyone's guess.

Some years ago we went to buy a low mileage approved used Landcruiser Amazon from a North London Toyota dealer, on the test drive we noted the steering wheel was at 10 o'clock with a slight pull to one side (i've had several LC's over the years and all have steered perfectly), which made me look closer, i found a new odd tyre sitting on the nearside front on a wheel that looked to be different age to the others, i suspect a hard blow into an object had shattered that tyre and wheel, but it takes a lot to knock an LC's steering out of true so obviously we walked away.

Odd tyres or kerbing damaging steering or low tyres pressure on one tyre.

Swap tyres around if the above factors are irrelevant. Check for suspension damage before sweating over castor adjustment.

And some older cars with torsion bar suspension had different wheelbases on left and right sides.

Not a Toyota LC but a van.

By now our pothole is probably well up to the job of destroying a LC. Why not bring it down and have a go? Perhaps we could get Land Rover to open an off roading course based around it.

Anyone know why we bother paying taxes? Because I'm beginning to wonder with the utter feckwit at Essex CC who thinks having a 'cavern' on a fairly big road is quite acceptable.
