What happens when you stick twin 36-inch wide tires on a Silverado Duramax with 6 feet of wheel spacers between them?
Perhaps unsurprisingly, performance suffers just a bit.
Generally speaking, a dual-rear-wheel configuration is reserved for larger pickups that want the extra cushion for a large payload. The Silverado 3500, Ram 3500, and Ford F-350 are all good examples of such vehicles that can optionally have two tires on either end of the rear axle.
Also generally, those wheels are placed close together. They don’t normally span half a football field, else they wouldn’t be able to drive on public roads.
But the internet is a place that is always asking the question “What if?” So what if a bunch of custom made wheel spacers were placed between a set of tractor tires and then slapped on the back end of a Chevy Silverado 1500 Duramax turbodiesel?
Then you get this abomination from YouTuber WhistlinDiesel (which comes courtesy of Jalopnik). Here we get to see what happens in real time as this ultra-wide pickup drives through the mud of a damp cornfield.
First step is to put a pair of 2-foot spacers between the rear axle and the first wheel. Then after that, a 36-inch tractor tire is placed. Next, another, custom made 4-foot spacer is placed on the other side of that wheel, and then finally another 36-inch wheel. This causes the rear end of the Silverado to span 24 feet, give or take a few inches.
In the front is a pair of skinny wheels that don’t so much direct the Silverado as much as they continually dig up the soft loam of the cornfield.
It takes a LOT of power to turn those massive tires. You can hear the tuned Silverado’s engine really work just to even crawl through the mud. The entire time, the Silverado’s motor is screaming like it’s racing down the highway, and plumes of black smoke belch from the straight-out-the-hood exhaust.
Initially, WhistlinDiesel is afraid of blowing the transfer case and keeps the truck in 2WD mode, but then gets stuck in the mud and forces it to switch to 4WD. By the end of the video, the engine light is on, the axles are all but bent, and god knows what has happened to the rest of his pickup’s drive train.
Worth it? That’ll depend on how many views he gets, we suppose.
