ORV torque spec for wheel lug nuts

Just noticed (after 5 years! ) that ORV has different lug nut torque specs for steel and alloy wheels. According to the manual that came with the trailer:

80-90 Ft-Lbs for steel wheels
125-135 Ft-Lbs for alloy

Any idea why?

The lugs and nuts are the same.

My truck uses the same specs irrespective of the type of wheel (steel spare or alloy).

Anyway, I've been using 125 Ft-Lbs for both.

Could be because the manual is for all models in 2014. The smaller creeksides used a 3500 lb axle which had 9/16" wheel studs vs the 5200 lbs which have 5/8" studs, which require different torque specs.

Thanks, that's a good point and makes a lot of sense.

Wonder if they clarify that in the newer manuals ...

My manual shows torque specs for both aluminum and steel too. I guess they figure all you need to know is what kind of wheels you have, steel or aluminum, and torque respectively. Since I have steel I torque them to 85.

Makes sense, as your 23RB has the 3500# axles, so like Rickioni says, you have smaller studs than the 5200# axles. And your spare is steel also.

But the manual is confusing when you have 5200# axles with the alloy wheels, but also a steel spare.

And I have two steel spares that I rotate in every year. And use the 125 torque spec on them. (The mix of wheels does look a little funny )

I'm just thinking the manual is written that way for the average joe (or sally). For most its likely easier to differentiate an aluminum wheel from a steel wheel than by their axles or lug nut size. I don't think you'd be under torquing your steel wheels at the recommended steel values or they would say so. But yeah, mixed wheels do look a little funny.
