We've only had the truck a few months and I think the spokes are all the way around. We've never had a big truck before so I just glanced at them and the tires. All looked like new. Never new there were issues like "widow maker" until I joined Stovebolt a couple days ago. I've been researching brake upgrades and while surfing forums ran across wheel issue.
The truck is at our farm about a 100 miles from here so next time we go over I was going to really look at all wheels. Just wasn't sure what to look for that's why I posed question.

There are various lock ring type open center wheels available and tubeless drop center wheels are also available.
Not sure what this comment means.
Thanks
