Wheel Balacing


Caravan guru

Recommended Posts

I am interested in your views on the need for and benifits of wheel balancing for caravans.

If any members have had this done I would be grateful to hear of their views on how it afected the stability and movement of items such as internal doors within the caravan when it is being towed.

I think that this subject was covered a while ago but having said that, I have just had two new tyres fitted to the van and the dealer had them balanced as a matter of course.

 

I would guess that it would be impossible to give a definitive answer as to the effect of un-balanced wheels have on a caravan, but judging from the effect out of balance wheels have on the steering wheel of a car, it seems sensible to have it done. After all, the van normally bounces around a lot when towing anyway and thats with balanced wheels!

tyres do not need balancing unless the vehicle is travelling faster than 60mph. seeing how the speed limit for a caravan is 60mph, there is no need for caravan tyres to be balanced.

Not only is it advisable, in my opinion it is essential. I have witnessed first hand the effect of unbalanced wheels on the internal structure of one of my caravans. I repeatedly had to refit loose furniture screws to this caravan until the wheels were balanced. I don't believe that it was coincidental that the screws all stayed in place after the wheels were balanced!

Sorry Mr Sheens, I have to disagree with your statement above. What about those of us who tow our caravans abroad? France for example has a legal limit of 130Km/h (82mph). Whilst the effect can be more pronounced at higher speeds, an unbalanced wheel doesn't necessarily start shaking at 60mph, but rather the oscillation slowly builds up with speed. The actual speed is dependent upon the severity and position of the imbalance relative to the rotational axis. It is particularly serious if resonance is achieved, as was the case with one of my previous cars. The steering wheel shook severely at just 40mph, but was not evident at higher speeds. The problem was resolved when the front wheels were balanced.

If this statement is factual, then why does the steering wheel of a car let you know that the wheels are un-balanced even at speeds of 30mph?

 

We tow on the Continent and travel usually at 70mph and occasionally at 80mph. ...get your wheels balanced!

according to my tyre fitter the caravan club recommend you have your tyres balanced. i must agree with them for a smooth ride,plus driving to spain twice a year i do tend to go faster than sixty.

Guest mr_sheens

ask yourself this question then. if it is needed why does no uk manufacturer do it as standard on any caravan they make?

and just to let you know that all uk manufacturers have informed me over the years that their caravans are NOT designed to be towed at speeds in excess of 60 mph.

I'll leave you to draw your own conclusions here. ..

With respect, this is irrelevant if an oscillation can occur below this speed.

I have had my tyres balanced when the caravan was brand new, (it stopped the table from dropping out of the cupboard)

 

They were well out,

If you are getting the tyres puncture proofed, it is recommended to have them balanced first.

 

We had this topic before, when a very nice chap from Elddis responded,

(sadly he received a lot of rubbish from some folk and disappeared)

 

I think it is really necessary

I would have thought it's only common sense to have the wheels on your van balanced,we all know what it feels like when the wheels on your car are out of balance! Anything that helps make the outfit more stable.

In all my experience with cars, badly unbalanced tyres show themselves at 42mph!! while I have also found slight imbalances to occur at much higher speeds, I cannot see a reason why this would not be the case with caravan tyres.

 

Therefore I would say it is paramount to balance the wheels for two simple reasons. Vibration from unbalanced tyre can and does contribute to nearside wheelnuts coming loose although the same vibration would probably have the opposite effect on the offside wheelnuts.

Further I am led to believe, imbalance is an ovality of the tyre which causes a hammering effect on the tyre as it hits the road and hence the vibration. This will lead at least to uneven tread wear and possible premeture failure of the tyre.

 

I must say though in my experience ringing round for quotes always leads to a price for fitting and balance plus hopfully a new valve at no extra cost. Why then are we having this disscussion?? :blink:

just how much would it cost to balance a pair then

43093[/snapback]

I paid £14. 25 for five wheels last August, so that would be £5:70 for a pair (but don't forget the spare). I had been quoted over £6 per wheel from one outlet, so I suggest you shop around as a couple of quick phone calls could save you pounds.

The problem of balancing has been answered, :)

Some in the caravan industry don't think they need it ;)

 

Well its more to the point that the firm that supplies the wheel with tyres has told them so. Explorer were looking into this problem, so we were told, a couple of years ago ;)

 

However "The caravan industry" they also think screws don't need tightening, (hinges, handles, furniture etc)

Handles don't have to be fitted (no one will notice)

warped doors are ok

creaking furniture is expectable

heaters that don't work properly are ok (truma problem)

and of corse(very) the odd dent is ok :angry:

and all dealers do a pdi :lol:

I am really annoyed to think that manufacturers are producing new caravans with unbalanced wheels. Why do we allow it? I suppose its our failure to be aware. When I bought my current van (new 2003) I bought a new spare wheel which I automatically had balanced. So for the last three years I have been towing a van with only the unused spare balanced. Wonder if thats why the fire front always fell off before it was screwed on? The cost of balancing wheels prior to mounting by the makers of caravans is negligible. I will insist that any new caravan has its wheels balanced at no cost to me! Feel like a campaign coming on. Suppose we should blame our own ignorance and apathy.

Oops, I got sidetracked, now back to the original question

In my earlier post about balancing,

I had a problem with the table falling out of the cupboard etc.

 

I was also going to have the caravan tyres puncture proofed, fortunately I checked on punctureseals & ultrasaels website they both highly recommend having any wheel balanced before having the job done.

When punctureseal/ultraseal is used it is in liquid form so it emphasises the balance problem, my dealer is an agent for it and never said a word (how may others have had it done without being told).

 

When I had them balanced they were well out, but I have never had the table fall out nor the draws on the floor since :) or had a sway or any problem when towing :)

 

or a puncture (touch wood) :o

 

When I had the car tyres puncturesealed by a firm in Sheffield the first thing he said was "have you had them balanced" :)

Any rotating mass needs balancing,unless you are attempting to fatigue some structure. :blink:

 

As the caravan assemblers do not manufacture the running gear for the caravan,I have emailed Al-ko Kober,who do, to obtain their advice on the matter.

 

I shall post their reply.

Not had a problem? ever thought why those screws come loose Paul!!...

. ..might vibration have something to do with it??

Hi,

 

Considering the cost involved, I would just get it done (and I have done). I'm still a relative newbie (2 years), but when I took the wheels off over the winter it made sense to get them balanced. I didn't even think to ask the question, given that I have experienced unbalanced wheels on a car. As the owner of an older van, I also think it makes sense reduce vibration where possible.

Garry, it was the last one in the showroom before the new model came out, more like they were robed, well used for spares for the others, and the bits were not fastened back.

 

I know its of off the original subject again :rolleyes:

 

but perhaps Jones Venings (or the manufactures) should do a survey with anyone who has bought a new van, say after a year and again after two or three just to see what service the dealer does, then award stars etc (much like the AA did with spanners when I was in the motor trade).

 

The manufactures (most) are getting a bad name for what is not checked at the dealers, with the pdi, and again when serviced.

 

When we did a pdi we had to make sure everything was right, even second hand (and not wait for the customer to point it out), our motto was if the customer is happy they tell their friends :) if not they tell everyone :(

 

I'm in the manufacturing of pallet racking business now, we make the racking, but have to hope the erection team sorts any problems touch ups etc. that have happened in transit.

 

However we always ask the customer if everything was ok, and how we could improve our service to him, the feedback is fastened to the factory notice board.

 

If the caravan industry (or all industry) did this perhaps we could all be a lot happier, and they would find which dealer deserves the best discounts, first choice of vans etc.

 

(rant over :lol: )

As a side comment we are told to regularly check the torque setting on our vans wheels due to numerous wheels having fallen off in the past. That is due to the fact that as most have no shockers the vibrations are transmitted to the bolts/nuts and can loosen them, it therefore follows that to reduce any source of vibration would reduce the cause of the problem and would make the need to do the checks still necessary but maybe not as essentially. The need to have the wheels balanced is then a no brainer. Like most things in life you can ignore them for so long then its a case of "if only".

 

Cheers

One thing I saw at the weekend which impressed me, was marker tabs on Elddis wheel nuts (bright coloured) so you could see at a glance if they had moved.

 

Don't know if they were factory fitted or the dealer had fitted them, but a very good safety factor :)
