So for a skinny tyre are Q78's a good choise?
From what I remember they are 35/11/15
Not many mini trucks run the the TSL/SX in Australia, most think that the extra side lugs do not flex as well as the TSL on a light truck. Your thoughts?

Q78 is a great size. Very effective in thick mud. You're about right, 35x11.

The problem with the SX's on a light vehicle is that they are a bias-belted tire. That means they have the heavy construction of a bias ply tire (with bias plies, of course) but they also have radial belts to try and achieve some of the on road performance of a radial. This extra construction makes for a heavy duty tire that has to run lower pressures to flex well under a light vehicle like a Toyota or Landy.

They are also a lot heavier weight wise. Size for size they are like 12% heavier than their regular TSL counterparts.

Strong sidewalls though, which can be helpful out in the bush I guess.

Side wall strength is important. The problem is within a 3 hours drive from Sydney we encounter everything from soft sandstone, sharp shale, hard granite, soft mud pits to heavy clay bogs. And most people drive to their favourite wheeling spot.

I know there is no such thing as a perfect tyre, but from what I have seen either the Q78 or Simex Centipede would be a good choise for my mini truck.Simex Centipede

In Oz both the Q78 and Simex Centerpides cost around A$420, not a cheap tyre considering a BFG 35/12.5 MT cost A$270.

Now who told me wheeling was cheap?

The Australian Simex site is currently down thus I pointed to the UK site.

I just needed info on the Q78 as the Interco website does not tell me much.

I have 2 friends who run a different tire (Buckshot Mudder) in the Q78 size that I have wheeled with extensively.

My previous set of tires was P78 buckshots. (33x10-15) I now run 33x12.50 Goodyear MT/Rs. I rolled one of my P78 buckshots off of a 7" rim at 15 PSI once. But they did quite well in mud.

The Q78s my friends run, they typically run around 15-20 PSI. Each lost the bead once at 10-12 PSI and mow runs them harder. They both run 7" generic steel wheels. These thin tires work great in mud, and nothing beats them in climbing out of ruts. They work well in most muddy situations as well.

The TSL/Sx is a very heavy duty tire. Many off-roaders stateside consider them the strongest offroad tire made. I have never seen on torn open on the trail. A friend of mine who runs them (35x15.50!) doesn't even carry a spare anymore, since he has run them 7 years without a flat or blown bead. But he runs beadlocks, and doesn't count on the vehicle for transportation.

TSL SX tires don't play nice on pavement. They wear out VERY fast, and are very seldom actually in balance. But offroad, they are my favorite tire. I just can't run them now because my rig sees too many street miles right now. They can flex VERY well - the sidewall lugs are broken up with cirumferential gaps to allow the tire to flex. But you must air them down lower than a typical bias ply tire to get them to flex, which means eithr you run a beadlock, or risk blowing a bead on the tire. Many of the vehicles around here running SXs run very wide tires (at least a 14.50 width) on 15x10" wheels to minimize this problem.

Basically, I would say that they are well worth the risk, because they are the most durable tire out there.

As far as not flexing, take a look at this:

Mean lookin tire. Looks very much like a directional version of the TSL with the Bogger sidewall tread.
Wonder if Denman makes those for Simex, or do they have their own mfg. facilities?
