To ensure consistent wear and to extend the tread life, tyre rotation should be a frequent component of your tyre care routine. By balancing wear rates from the front to the back and from the side to the side, you can look for the Tyres in Hawkesbury area. T

Why U-bolts may be the Major Cause of Accidents
New Post has been published on https://www.couplemate.com.au/blog/featured/u-bolts-cause-of-accidents/
Why U-bolts may be the Major Cause of Accidents
U-bolts are not usually assessed as the culprit in Caravan accidents or rollovers, possibly due to the enormous accident carnage.
Bad bearings, broken springs, loss wheel nuts are blamed as the cause of the accident.
However, the culprit in many instances is hydrogen embrittlement embodied into the u-bolt during manufacture.
Hydrogen embrittlement is one of the most underestimated processes in the manufacturing industry.
Fact: Hydrogen embrittlement is embedded into all steel products that have undergone some form of heating process.
Example, plating tow balls install hydrogen embrittlement into the tow ball. Tow balls must then be de-embrittled via a slower reheating and cooling process to remove the embrittlement.
Read more about hydrogen embrittlement here.
How do I know if I have the right u-bolts on my caravan?
U-bolts are often overlooked and just not on the maintenance checking schedule before your next caravan trip.
It is difficult for manufacturers to produce a standard u-bolt as there is no Australian Standard for caravan or trailer mounted u-bolt.
Couplemate have decided to undertake u-bolt tests to a standard similar to rated Dee Shackles. The test for dee shackles is breaking load limited (BLL) / 6 = working load limit (WLL). (not the ATM). To calculate the ATM divide the WLL by 1.5.
Example, if heavy duty u-bolts break at 23t, the rated load limit is 5.75t.
ATM is calculated at 5.75t / 1.5 = 3.83t max load.
Therefore, a 5/8″ Couplemate u-bolt kit has been tested to a maximum ATM capacity of 3.83t
The image on the right is from our 200t test rig. A force was gradually applied until breakage occurred at 23t. We called this the BLL or break load limit.
By applying the Dee Shackle or Bow shackle testing regime, we can apply a maximum safe rating of 3.83t per axle for this type of u-bolt.
Heavy Duty U-bolt Kit specifications are
2 x 5/8″ BSW Galvanised mild steel u-bolts
4 x 5/8″ BSW nylocks and washers.
1 x 10mm Galvanised mild steel plate.
Springs, Axles and U-Bolts
It is a common practice by some caravan manufacturers to put spring under the axles to give extra height. Contrary to popular opinion, Couplemate not only thinks this is a bad idea, but it is unsafe and contributes to road accidents.
Axles are usually located above the spring and enclosed by the spring and the chassis rails.
What buyers do not know is there is no Australian Standard to test u-bolts used by caravan and trailer manufacturers.
A process called hydrogen embrittlement causes u-bolts to become brittle and fracture on the bend of the u-bolt.
The u-bolt on the left was bend by bare hands. This is hydrogen embrittlement. U-bolts become so soft. No chance of effectively clamping your axle to your caravan spring.
A fractured u-bolt when the axle is under the spring means the axles can easily break free once the u-bolt fracture and discharge itself out the rear of the caravan. The potential for road carnage to innocent travellers behind you is horrific.
Couplemate tests its u-bolts to destruction under its standards, due to the lack of Australian Standards, so we are well aware of this problem.
Our remedy to combat hydrogen embrittlement inserts an additional process into the manufacture of u-bolts. This process removes hydrogen embrittlement.
When making your spring choices be sure to purchase Couplemate u-bolts.
Snapping U-bolts
Hydrogen embrittlement can be readily determined by breakage at the corner of the u-bolt when it has been bent.
All bends should have a least a 5mm radius otherwise they will not match the 5mm radius curve on your axle. This radius is a critical pressure point. It is easily eliminated.
U-bolts are the only thing holding your entire caravan onto the road. They bind your axle to your springs and then your chassis.
U-bolts are not a disposable item like grease or bearings or tyres. They are in place for the life of your caravan,
Please excuse me if I am OCD about ubolts after witnessing images from accidents.
How important is a u-bolt check?
I installed new u-bolts in Brisbane and headed down to the Hawkesbury River for Christmas with the boat in tow. (top image)
Lovely, uneventful trip but now its time to check a few things.
Top of the list this time is u-bolts. Told my brother-in-law, all about mild steel stretching and how these nuts will probably tighten 1/2 turn.
Now, I’ve been known to twist the truth in a past life, so bullshit was called.
Therefore, the whole caravan park gathered on the bullshit call.
Thank you, Jesus and Merry Christmas. All the nuts all needed 1/2 a turn to make them tight again.
When was the last time you checked your nuts?
Especially on new caravans. Do not wait for the first service for what looks like a faulty spring is actually lose u-bolts.
Grab your wrench and socket. Test them and tell me what you found?
Tip:
Check your ubolts for tightness every time you pull your wheel off to check your bearings. If you have nylocks, they will ned replacing if removed.
Ubolts are made from mild steel, stretch and even break under shock loading. I always check mine, and I ask you to do likewise for your safety,
Finally, I would love to hear your comments below and your opinion on broken U-bolts and how close you were to disaster.
The video below is about a boat owner who had a shock loading event that snapped his u-bolts. What he did not know, was his old u-bolts were likely to have been suffering hydrogen embrittlement.

What are the different types of tyres?
Tumblr media
There are many kinds of tyres on the market, which can make it hard to choose new ones for your car. Tyres are made to fit different kinds of vehicles, like 4x4s, vans, or cars. They might also have various tread patterns to give the best performance for each season.
Before you buy new tyres in Windsor, you should look at the different kinds and choose the ones that work best for your driving style and needs.
1. Winter tyres
Winter tyres have a lot of grooves and cuts in them so that they can grip better on snowy, icy, and wet surfaces. For safety, they are made to stay flexible even when the temperature drops.  
2. Summer tyres
Summer tyres, which are also called standard tyres, are made to offer high levels of performance and are best for temperatures above 7°C. They are made of softer rubber, which makes them more stable and grips rubber, and they have a tread pattern that keeps them from hydroplaning.
3. All season tyres
All-season tyres are made by combining the technology of summer and winter tyres. They work well in all seasons, but they aren't as good for summer or winter as tyres that are made for those seasons specifically.
4. Budget tyres
Debating whether to buy cheap or expensive tyres for your car? Before you buy something, make sure you've thought about everything.
5. Energy saving tyres
Energy-saving tyres are made to have low rolling resistance so that they use less fuel. This helps drivers save money on gas and cuts down on CO2 emissions. Most of the big tyre companies make tyres that use less fuel and are designed to save energy.  
6. Run-flat tyres
Run-flat tyres are made to keep you safe on the road if you get a flat while you are driving. They can be driven on for a short distance after getting flat because the sidewalls are thicker and stronger than those of regular tyres.
7. High-performance tyres
High-performance tyres are designed to respond quickly, grip the road better, and be able to handle high speeds. These tyres are made by high-quality companies that got a lot of their research and technology from their time in motorsport.
8. Tyre pattern
Even though they look the same, tyres are made with different prints and patterns to meet the needs of different drivers. Each tyre pattern has its safety and performance benefits, and you should choose the one that works best for your needs.
Take a look at all the tyres and then take the decision wisely. To get all the information about tyres in Windsor, just give us a call.

One axle needs new tyres, but you might be wondering if it makes sense for the car to use various tire manufacturers. Using cars with mixed Tyres in Hawkesbury is much like wearing two different pairs of shoes.
