Trailer / Bearings / Ax Capacities

[Dignity]

The other thing that you need to be careful of is that the rims are a registered trailer rim, many an insurance claim has been voided by people using car rims.

Don't think so, I will check tomorrow and let you know via PM

Noelm, PM sent

Noel that is a bit of a worry, i have 6 of those 6x9 wheels all mine are alloy rims they could become fragile when twisting on dual axle trailers, my dual axle trailer u guys have probably noticed my wheels are really close together maybe for this twisting reason?

I think they are strong enough, they have been made for years and I have never seen a broken one, had them on a few trailers over the years, and I have seen them on big caravans too.

I shouldn't have ignored some cryptic message about leaving the page, resent.

Scared the crap out of me the first time I got a dual axle trlr, now I don't look at them except to line them up with the traffic bollard so I know I have the correct clearance in my carport. The closer they are together probably stops them trying to fight each other either that or the lead wheel blocks the view of the one behind 😉

Not too sure about the "correct" spacing for duals, I know when I replaced my springs recently I had to get them from a place in Sydney because they were the only ones that had them long enough, either that or get them custom made.

Can't figure that one out either but if you check the tyres the dual rating is lower than the single axle rating, this one I understand.

Edit. OK had to think about it but, and this is with dual axles if I go around a sharp bend like the cul de sac at the end of my street or reversing into my yard both front and rears on the duals react differently, sometimes one leans in one direction the other often in the other, only slightly, I guess bigger rims more leverage on the hubs in these situations. Only a guess.

Morning Sam, I had asked the same question when enquiring about re-rating my CT with 17" Prado rims - Apparantly 15" rims are able to be rated higher than 17's - I'm baffled by this, so my best option is to strength my drawbar (currently 75x50mm) with a ladder (20mm roundbar construction).

With regards to varying ratings with increased wheel diameters it comes down to leverage forces on the bearing and axle.
The bigger the diameter, the more leverage and increased forces.

Hence why most extra heavy transport trailers run far smaller diameter wheels at the expense of running the wheels at higher rpm.

I remember that jargon. The other bit of tripe I remember hearing was that I needed to be a certified welder to modify my CT - mind you I did build it from scratch myself - but that's not the issue old mate wanted to hear. I think he wanted my business.

Mike, it is easier to rerate your trailer than you think. How close is your rego due, as time comes comes closer give me a buzz and I'll let you know how.

Sam, we'll catch up for a chat after you return from 1770.
