In regards to duallies: why can't you just get thinner tires to increase the gap

[vintageracer]

Just make sure your rear dually tires do not touch at the sidewalls!

Lots of guys put Big Tires and wheels on there dually with the rear tires rubbing one against the other on the sidewalls. This causes HEAT which can and will degrade the tire and cause tire failure that is typically internal tire belt separation.

Good friend just replaced all six tires on his 4x4 dually as the rear oversize TOYO tires he was running would touch at the sidewalls creating extra heat within the tireswith the result being belt separation in 4 different tires in the rear all with 7K miles or less on each of the tires. Last Saturday all 6 TOYO'S replaced with new tires in the proper size for his truck with the proper gap between the dually tires. No TOYO would not warranty all the tires due to the improper size of tires mounted on his 2001 Ford F350 4X4 Extended cab dually as well they should not.

Duallys are designed to have a gap between rear dually tires for a reason!!!

How wide are the trails where you go off-road?

As wide as I make them...

The booger-eater's "solution" to that problem, is to use wheel spacers...on a 350, 450, 550, 650, or 750 truck- often towing a giant trailer at 85 mph...

I've been told that duals don't do as well in the muck and mud since the rear track is different.

On this, this is also a problem with some single rear wheel pickups where the rear track is narrower than the front.

Also an issue if the vehicle is a different width than the ruts, In ‘96 we got 3’ of snow over night. We see so little snow that the city doesn’t have much snow removal equipment.Following the ruts left by a full sized vehicle in my Fj40 was terrible. It kept Sliding back and forth and was all over the place. So width is s big issue when there are ruts. I’ve also had the same happen in mud, and it has nothing to do with tires and wheels,

I have a dually thats near maximum rear axle weight and I would argue against trying to run on one tire in the event of a flat. The single tire will be grossly overloaded and will flatten considerably carrying the extra weight. This will create lots of sidewall flexing which will heat up and damage the remaining tire quickly. You may get away with it at low speeds on an empty dually pickup, but I have removed an outside tire on my van and even at max rated pressure the inside tire flattened to the point that I wouldnt drive it ten feet.

You would be extremely shocked on how far you can go with one tire missing or blown. your tires are capable of carrying much more weight than what is stamped on them. At least 50% more.

I am not aware of an american-made diesel DRW truck made in the last 15 years that has not been uprated in stock form to over 40,000 lb. Some of todays 1 ton trucks are really medium duty class trucks with creature comfort

Of course use common sense and get your vehicle back to 100%.
