Test #3: Rock Crawl
Now off to my favorite part, a short rock crawl. I picked a spot again that I have done on 4x4 quads before. It not only has ledges, but has loose shale type rock that is
hard to get traction on.
Haim again went first and took Johnny along.
Once again we talked after we both had our turns in each vehicle. My first thought as I watched Haim having some problems with the Bighorns Radials was that the
Moapa’s Bias ply did better since I breezed through the rocks. Then I switched to the Bighorn Radial and made it look equally as easy. I believe I just happen to take
a better line. Both tires grip the rocks extremely well. I would have no problem running either tire on my vehicle. I navigated the 2 wheel drive machine up a couple of
ledges that I didn't think was possible in 2 wheel drive but both tires flexed on the jagged rocks and gave me all the grip I needed.
Test # 4: Cornering
As we were heading back towards our staging area I stopped where the road makes a 90 degree turn. The road at this spot was fairly smooth with a loose granite surface.
I asked Haim if he would take each TomCar and see if he could get them to slide. He made three passes with each tire and for the first time said he could feel a difference.
He said the Moapa Bias ply tires did not slide and wanted to track around the corner.
The Bighorn Radial on the other hand could be pitched sideways and slid around the corner.
The difference does not make one better than the other, just different. There are situations where you may want the tire to either stick or slide depending on what you are looking to do.
Test #5: Sand
For our last test of the day we headed over to some small sand hills. We tried them again back to back with the same results. We were able to go about the same
distance with each tire before digging into the soft sand. On one run in low with the Bighorn Radial, I went until I was digging in and engaged the diff-lock lever then
floored it. We started moving but were soon buried to the frame.
It was fun though, throwing a huge roost of sand. Oh well, Haim was there to pull me out. We did one last run with each machine in low and with the diff-loc engaged.
Both machines made it with ease.
Test #6: Visual Inspection
When we arrived back at the trucks we inspected the tires for any damage. The only thing we found was that the Maxxis Bighorn radials showed some signs of wear/chunking
on the tread blocks. I say this was probably due to a few instances during our rock crawl test. The rocks in that section of the test were very jagged and sharp. The DWT
Moapa bias tires showed no signs of wear from this ride.
Both tires performed remarkably well for the extreme conditions we put them through. Our original thoughts were that we would see some very stark differences between
the Bias ply and Radial ply tires but for our test we found very little difference. We even remarked if we were blind folded when we got in the vehicle and never look at
the tires we would not be able to tell which tires we were riding on.
If we look at the prices there is a pretty good difference between these two models (Moapa being less expensive). Given the very similar performance characteristics we
experienced here the Moapa may be a better buy if you are on a budget.
The two biggest factors that may have affected our results are the TomCar's suspension and weight. The Tomcars we were testing have 17 inches of travel so they can soak
up a lot of bumps and imperfections in the terrain. Also, the TomCars tested weigh in at 1848 lbs dry. These two factors help give the Tomcar an exceptionally smooth ride
but may have made it difficult for us to feel subtle differences between these two tires.
The only spot where we felt there was discrepancy between the two tires was trying to slide the machine sideways. The Maxxis Bighorn Radial would slide through the turn
but the DWT Moapa Bias ply did not want to slide. They would grip and pull through the corners rather than slide.
We would not be disappointed with either of these tires after seeing the results of our testing. They both held up very well, especially considering we were trying to see if we
could destroy them. Future tests on other vehicles may be down the road.
