Hi, this is Mike, I'm an adventurer and a dad and this will be a quick one. We're going to talk about wheels, and why you might want to use a wheel that's different than the stock wheels that came on your 4x4.
So, I've been modifying our 2017 Toyota Tacoma TRD Off-Road with suspension and tires, and if you want to learn about some of the decisions I made to enhance the performance and comfort of the vehicle for our off the beaten path adventures, check out the playlist in the card.
In order to open up some more options in tire sizing, I needed to change the wheels from a 16" wheel to a 17" wheel. There are a lot more options from almost every manufacturer if you have a 17" wheel.
I decided to go with the Method Race Wheels trail series 703. These are a 17 by 8 and a half inch wheel with 0 offset and 4.75" inch of backspacing. Which makes for a nice tucked in wheel tire setup.
There are three main reasons I went with Methods, and the 703 specifically. Other than the fact that Michael Shaffer from Rogue Overland is running them. But if I'm being honest, that's the main reason.
Anyway.
Bead Grip Tech
The main reason to choose these wheels is that these have what Method Calls, Bead Grip Technology. To understand what that is, you need to understand what a bead is.
When they make a tire they start with two coils of steel wires wrapped tight, then encased in rubber.
These beads are the interface point between the wheel and the tire and are the basis on which the rest of the tire is built.
Check out the video in the description for how tires are made.
These are the stock Tacoma wheels and they have a little cove that is an extremely tight fit with the bead. When pressurized, the tires will snap into that cove and the air pressure keeps it seated there and the friction of the bead on the rim transmits torque from the axle through the tire to the ground. So the bead has a lot of work to do.
If you are lowering the pressure in your tires for improved traction, at some point when you get down below about 12 PSI, there isn't enough pressure to keep the bead in that cove and they'll slip off and basically unmount the tire completely. At which point, you'll have a bad time.
The Method Wheels have two things to prevent this and allow you to go down to a lower pressure than you would with a regular wheel.
First, and most obvious, they have these rough ridges where the bead rests that dig into the rubber and make it harder for the tire to slip sideways out of the cove.
Second, they have what Method calls an "Enhanced Safety Hump"
This enhanced safety hump keeps the bead from sliding off to the inside of the wheel.
Lastly, Method has a whole range of wheels that use Bead Grip Technology, but I went with the 703 specifically for weight reasons. This wheel weighs 27.6 pounds while the 704s are 32#.
These Stock Tacoma Wheels are 25#. And of course, anything with a fake bead lock ring is going to be considerably heavier which is not what you want.
Check out Michael Shaffer's Little Black 4Runner on the Rogue Overland channel for some footage of what the Bead Grip Wheels can do. He told me he has no problem going down to 10 PSI with these and not loosing the bead. kzbin.info/www/bejne/rIm8Zq1_dp2Ehbs
So how strong is that bead grip thing really? Well, I can show you...
When we mounted these up at Silver State Off Road, Lance had to use a lot of air pressure to get them to slip over the enhanced Bead Hump. The inside bead snapped on first and it was pretty loud. But you can tell from the camera shake here when the outside bead went on that it was quite loud and shocking. All 5 times.
It took several minutes to develop enough pressure to snap them on and it surprised us each time. I've even heard of tire shops having trouble getting them to de-bead with standard tire machines.
So The take home is that they are strong enough for anything I'm likely to ever do with this Tacoma. Unless things get really crazy...
How low can I go?
That remains to be seen. I got these mounted up towards the end of summer and haven't had time to get them out and really stretch their legs.
For overlanding, these are great down at 20 PSI. I've run them at that pressure a bit and they do really well.
For rougher stuff I'd probably lower them to 15psi. I've had good luck with my 4Runner at that pressure.
If we get into sand and snow, I might try taking them down to 10 PSI. In those situations, flotation is really important.
