TJ pulling to the left...

Hi all - a couple of questions...

Anyone had any problems with their TJ pulling to the side (in my case a RHD pulling to the left) after swapping from stock to 31+ tyres? Its not overly noticeable but is certainly there, and certainly was not there with stock tyres...?

I'd heard a rumour that a 'pull' to the side may be built in to some vehicles - in my case a pull to the left would make sense, driving on the LHS, but I can't really believe this to be true.

Also, although the tyres are new on the stock wheels and were sealed I'm losing a fair amount of pressure - over a week in the worst case around 7 to 8 psi...

Any ideas?

It could be possible that your jeep is not aligned properly. If you have a lift kit, did you align your jeep afterwards? Sometimes putting on bigger tires throws off the alignment of a jeep.

I have never heard of a pull being built into vehicles. Perhaps your air pressure is having the affect of pulling by one tire running a lot lower than the others. Just by going to 31 inch tires is not going to have any effect on the alignment.

Take it back to whomever mounted the tires. It sounds as if you may have a faulty valve stem. The loss of pressure could definitely cause the pulling.

Howdee,
I have a RHD TJ (in Australia), so we drive on the left hand side of the road too.
If what you are describing is a gradual wander to the left (not a sudden veer) then we all experience it down here as well.
One theory put forward is that most roads aren't flat. The middle of the road is slightly higher than the edges to help with rain run-off, so we are constantly driving on a slight incline.

In Australia, we have some VERY LONG stretches of straight road with almost no traffic, so I did an experiment driving on the right hand side of the road.
All tests done at 50 - 60 mph.
Occasionally the Jeep would veer to the right.
Mostly though, it was just much less inclined to veer to the left and would go dead straight for ages but would eventually (and much more slowly) veer left until the Jeep wandered over the middle of the road (to the left hand side) , then the veer would become more pronounced.

Other problems like losing pressure or alignment would also add to the problem.
Spray some soapy water on the valves (or around the bead) if the soapy water bubbles, you have found your leak.

TJ pull to the left...

Hi all, and thanks for the feedback.
Admittedly the 'pull' to the side is very light, but noticeable when you lessen grip on the steering.
I'd considered the camber in the road, but it seems to be present on 'flatter' roads also.

As for the pressure, for sure its more obvious with lesser pressure on one side, and I hadn't thought of the valves (doh!) - so I'll do the soap test. My TJ isn't a daily driver so I'm checking the pressure before each outing which is a pain, but if the valves are an issue I'll get the swapped out...

Cheers
