New Super Single Tire Option

[MSGGrunt]

New guy into my Fuso build and like a lot of people I am making the switch to super single wheels and tires. I read that a good number of you recommend the Toyo M/T. I did some searching on Tire Rack and they only offer 1 tire in load range F, which is a 12-ply tire, and that is the BFG All Terrain in 37"x13.5"x17". A number of tires in load range E, 10-ply, including the Toyo Mud Terrain. All of these were around $500.00 a tire.

I then stumbled upon these. New company in the tire market. https://www.teschetire.com/308.html
A US designed tire made in Thailand. Load range F, 37"x13.5"x17", 12-ply with 3-ply sidewalls. For $282.00 a tire I thought I would give them a try. My build is in its infancy, so these tires won't see any serious off-road in the near future. Mostly getting acquainted with the truck shacking it down around town and maybe a 45-minute drive back and forth to work.

Here in Australia there have been numerous issues reported with 17" super singles failing.
From my understanding of this issue, most of the failures were caused by over heating due to running at a weight that was near the upper limit of the tyres.
Tyre temperature is something that can be overlooked, but it can get worse when you air down for off road driving, especially if you don't slow down enough.
Just thought I would mention that.

Yep, and a 3 ply side wall will get hotter than a 2 ply side wall at the same pressure, load and speed.

That specific tyre has a load rating of 1800kg (load index 128). That's 3600kg on the rear axle. The front axle is rated 2800kg max, so that's 6400kg all up - that is short of the 6500kg GVM for the Fuso FGB. I don't know about the US, but in Europe and other places that would be illegal. To be safely on the right side of the law, a load index of 131 minimum is needed to achieve 6700kg. I had a look at all the 17" tyres over all five tread patterns, and only one tyre scraped through by 100kg having a 130 load index (285/70-17, equivalent to 33").

@MSGGrunt - What year/model is your rig, and what is the front axle load rating and GVM?

Very long high speed runs across the outback when it's 110F... maybe?

Or driving at 30kph across the Simpson Desert with reduced pressures when you should be doing 20kph.

Load range and pseudo ply ratings don't mean anything. You need to look at the load index as BigSkyBrad mentioned.

In 37x13.5r17, Fury Country Hunter, Toyo Mud, and Nitto Mud, all have a 131 load index, 4300 lbs per.

If you bump up to a 40, the Atturo Boss has a 136 rating, 4940 lbs each.

2005 FG140.

Load index on their site is listed at 121 with a single max load of 3195 pounds. See how these work out during my build while I am still lightly loaded and if I need/should upgrade to the Toyos or Nittos I will.

I can see where going to singles in the rear the load index will be even more critical.

If you are in the US and not registered commercial, you can likely do as you wish. But a 121 load index is a poor choice for this vehicle, if you plan to build a camper on it. I guess you already bought them?

 

[MSGGrunt]

I did already buy them and there won't be a camper on the back for a while, probably long enough for me to wear these out and then in the future buy the Toyos or Nitto's.

I'm running this tire 37x12.5x20 load rating 3980lbs

Weight should be 18% less than the maximum, as a goal
