Bolt Pattern on Sierra 330RLS

I need to buy a spare rim for my 2015 Sierra 330RLS 5th wheel. I know that it has 8 lugs and I think that it is the 8X6.5 pattern but not sure. Can anyone verify for me exactly what the lug bolt pattern. The reason that I want a second spare is that we are heading out to the Grand Canyon from North Carolina in April and I will feel better if I have two spares for the trailer. I already have two spares for my truck. I have measure the trailer as best as I can but did not want to jack it up and take a tire off unless I had to. I even looked in the owners manual but it said nothing about the bolt pattern.

Luckily, 8 lug is a pretty standard 8 on 6.5 pattern so odds are you're right.

How accessible is your current spare? That should be easier than removing one of the regular wheels.

Here's a link showing the measuring pattern, in case there was a question.
