Wheel balance

[scrumpydude]

The steering wheel on the Terrano had started to shake, typically at 60 mph. Decided to get that sorted and get the front wheels balanced. Well, one wheel ended up having 90 grams added to it. A record for me IIRC. Anyway, back on the road and its worse. Seems to shake anywhere between 50 and 70. You get periods of no shaking when accelerating but sit at any constant speed for a while and the shakes come on.

The tyres on there are 'Forceum' brand. No, me neither. They are getting near the end anyway so it might be time to give the old girl two new pairs of shoes. Oh yeah, the tyres had "rising edge" wear i.e. the front edge of the tread was higher than the rear edge.

My questions are:
Could this just be the cheap tyres? Or could this be a mechanical issue? If I get 4 new tyres and the tracking done is there anything else left it could be? I'm think of horrible axle/hub problems. Finally, any recommendations for a fairly cheap tyre?

Try changing all tyres front to back and then go for a run and see how it feels.

Just out of interest I had a similar issue on my 05 plate, also got a sort of rumbling hum with mine and started between 40 and 50. Turned out to be the front prop shaft. Someone changed one of the uj bearings which changed it but didn't cure it. Turned out to be the slider bearing on the front prop shaft, it had what felt like a little movement. Removed the front prop shaft and it removed the problem. Found a good second hand shaft and it was fine. Not saying yours is that but if you change wheels front to back and don't fix it then try removing the front prop shaft and see if that fixes it and take it from there.

Change tyres and get rebalanced, if there adverse wear on one edge this could indicate that you have other issues however.

Check all of your bushes etc and tracking as this could be why they are wearing the way they are, don't knock a tyre company you've never heard of, give them time, read the reviews and let others research inform you

Wheel wobble

We get issues on a lot of Mercs & Smart cars with this problem and often it is a badly buckled or flat spotted alloy wheel caused by speed humps or potholes.

Cheap tyres can be the cause so as previously stated by others try front to rear swop if still the same check for ball joint & suspension play.

Hahah that's nothing I have malatesa kamians and one wheel alone needed 190g they're stuck on 3high lol good old retreads. But if its worse get them rebalanced you'd be amazed how many numpties get put on tyres machines that ain't got a clue. If no better after start looking at track rod ends or ball joints for access ware

Well, the tyre shop said they were cheap. Took your advice though and did a search for Forceum reviews. Found that the main complaint was lack of grip. I can agree with this. Have had the back end step out once or twice in the wet. Wasn't expecting that in such a 'sporty truck'.

Anyway, I think I'll end up replacing the lot as they are getting due and it's a good way to discount the tyres as the issue. Will get tracking done at same time. Question, can they balance a wheel without the tyre - just to confirm the wheel is true?

Wheel bearings were noticed has having a bit of play in them at the last MOT. They were tightened a bit and tyre shop said they had a bit of play but were 'ok'. Hmmmm. All starting to sound pricey.

They wont be able to balance it, but nothing stopping him from bolting it to the machine and spinning it at a high RPM, any buckles should then be visible by eye :thumb2

Had similar issue but would only happen at about 55 mph to about 60 mph. Badly worn universal join on rear propshaft was the cause. Was easy enough to check the universal joint by lying under the vehicle and shaking the propshaft and seeing movement at the joint. Not an expensive repair and not too difficulty to do.
On tyre recommendations its probably true that you get what you pay for but personally I prefer a winter-M/S type tyre for road use and have have had no complaints with cheaper tyres--as long as the thread is not allowed to go too low.

This type of out-of-balance on a 'balanced' tyre can be caused by tyre deformation at certain speeds, ie. lumps or tread lift/sink. Difficult to find but try rotating the wheel slowly & check for run-out or any damage at all especially local lifting/sinking in the tread area. The larger the tyre the worse the potential problem.

Apologies for resurrecting this thread from the dead but just to say tyres were the cause of the juddering. Had all four replaced with Cooper Discoverer AT3s and the old girl is a joy to drive. Quite why it took me so long is to my shame.
