15 x 8" Wheels - Quality

I bought some sunraysia style rims (4) for our caravan and initially had two fail (small crack appeared in the front bend line of the rim giving them a slow leak). They were Infinity brand, white with a single blue pinstripe) I had them replaced under warranty but they also ended up with the same fault. In all the whole 4 failed. I'm using ROH brand and so far no problems. Aussie made and 5 year warranty

Have a read of thread 63828 and also do a search for sunraysia on the forum, lots of info. Hope this helps.

Cheers

Hi Imsat,

ROH are having a stock clearance at the moment, I just bought ten Black Traks for Dave & myself.

Very good prices.

A guy I work with had sunraysias on his caravan. He would always check the wheel nuts for torque before any trip. Usually they'd be a bit loose, which in itself raises suspicions. Anyway, the one time he forgot to check them, the nuts on one wheel worked loose, chewed out the studs on the hub, wheel fell off at 90kmph and he was left with a hefty repair bill and a spoilt holiday.

Now, working as an engineer for a large Aussie auto manufacturer, we obviously went through a root cause analysis investigation. To cut a long story short, there were two contributing factors.

1. The paint on the wheels reduced friction between the wheel nut and the rim (not the main factor, but certainly a contributor).

2. The biggest contributor was that the area where the wheel nuts clamp onto the rim was flat. This provides no preload onto the wheel nuts. OEM steel rims generally have raised/domed areas which act in the same way that spring washers work. This, combined with No. 1 allowed the wheel nuts to work loose. Explains why his wheel nuts were always loose everytime he checked them.

Other observations were that the rim wasn't a snug fit on the stub meaning that all the weight was being supported by the studs. This is commonly overlooked by people when buying aftermarket rims, and its a huge NO NO. Wheel studs are not designed to carry that sort of force.

He has since replaced the wheels with OEM car rims and after several long trips the wheel nuts haven't moved off 110 Nm. Problem solvered.
