Is it normal for blockier treads to pick up more nails and stuff, and therefore get more flats?
I'm looking for an alternative now, maybe Toyo open country RTs. Those puppies sure are costly though.

Maybe you should drive a different route. Nails will make any tire loose air.

I'm surprised you are getting so many nails etc. embedded in a steel belted tire as opposed to others that have no steel belting. My preference to
BFGs was heavily influenced by the steel belts and the extra thick sidewalls to reduce rock slashes, especially when underinflated.

I'm in full shopping mode and turning up lots of unknown brands. The nomad earlier was right -- there's a "Baja Boss" tire  .
I was under the impression my Tacoma couldn't take wider tires, but Walmart online seems to say this will fit:
https://www.walmart.com/ip/Venom-Power-Terra-Hunter-X-T-All-...
That one looks really wide, to a degree I might have assumed wouldn't fit a Tacoma, but which might help on the Mag bay marine mud I sank into a
couple years ago . . . |
That is the factory stock size for a TRD Off Road Tacoma (265/70-16, or ~31").
Once the factory tires were replaced, I have always gone up to the 265/75-16, or ~32" tires, any brand. This gives you 1/2" more ground clearance and
will not rub, even when turning, as a larger size will (without a lift). Another plus, is that the speedometer will read correctly! The factory tweeks
the speeometer to read about 3-4% faster. I heard to keep you from getting speeding tickets? The negative is that the odometer will read about 3-4%
less on the highway, but when deflated for off road, reads spot on!

David, I also run 265/75/16 tires on my Trooper. They are a load range E tire which is designed to carry much more weight than I will ever carry, so
I run them at 28psi highway, and 20 on long dirt adventures.
Even at that low pressure, they seem to have a stiffer ride on pavement than the 265/70 load range C tires that I used to run. The stock size was
245/70/16, which did ok, but larger is better for where I go.
I think that the C load range tires were better crawlers, and have been told that the stiffer sidewalls will actually suffer more from over flexing at
low psi than the lighter weight tires. Does anybody else have any direct experience with that theory?
Edit, No flats or leaks on my last adventure from spines, or nails, even though just about every time I walked my dog around the area of recently
constructed homes where I was staying, I was picking up screws and nails!

Mine are not the heavy load ones... Chalk-tested, idea street pressure is 34 psi and they float on Shell Island's bottomless sand at 18 psi.

I run bfg ko2 load range e, because i tow trailers. Great tires.
Truck tires are a bit rougher ride. I would run p tires if i wasn't towing, as p are softer ride.
Woke!

It's fully possible that I've been doing it all wrong RE tire pressure . . . for driving a Tacoma TRD off-road around, usually with light to medium
loads in the back (usually pretty heavy on Baja trips), is 40 psi reasonable? Too high, too low?
I feel sheepish asking among obvious truck/mod experts, but I'm so focused on kayaking and fishing that the truck is mainly a means to and end -- but
of course it has to have clearance and non-flat tires to perform that important role!
In my previous truck, I was happy with Yokohama Geolandar AT tires, so I'm thinking maybe to go back to that with some added off road tread with the
X-AT.

David I too went to the 265/75R16 (32 inch) for my 2004 Tacoma and the speed odometer is dead on however on my 2006 4Runner I went to the 32 inch and
the speedometer is now off by about 2 to 3 mph. At 60mph I'm doing 63mph. Stock was 265/60R18 (31 inch tire) speedometer OK. 265/65R18 (32 inch tire)
speedometer off.

So you are saying the Nitto is the best tire for a pavement princess?
I kid amigo. That's a sweet looking truck. Why load F? Did you look at the AWT on the Nitto?

Normal psi on my truck when not towing is about 70. Max 80.
I run it a little below 35 in the dirt.

I had 3 sets of the Nitto Trail Grappler before these. Those were ATs. The Ridge is more of a hybrid.
Have done thousands of miles offloading in Baja with it.

Sorry if this is a bit off-topic, but we talked about a decent pressure to run KO2s on a Canyon crewcab for dual purpose use on another thread. I
found 35 psi on hiway was fine as per the specs on the door, and 25 psi for off road and hiway combination helped a lot to reduce the washboard
vibrations and body shake damage on the off road sections. Thanks to all those who contributed advice on another now buried thread.

Subject: What are the best Baja Tires?
Your flats have nothing to do with your choice of tires, but it is your choice of where you drive.
I am sure you can find better tires with regard to less flats, but I believe you will get the same results regarding frequency of flats for any other
brand.
Bottom line the BFG KO2 tire is just fine in Baja.
Tire pressure matters. Correct tire pressure is based on the weight on the tire. The manufacturer has charts to tell you what the correct pressure is
after you go to the scales to determine the weight.

Use the vehicle placard air pressure if running stock size/type of tires. If using non-stock type/size, then use the load & inflation tables to
select tire pressure (based on load) for paved roads. The “chalk test” is nonsense.
Woke!

Do the chalk test... perfect pressure for your vehicle's tires on your vehicle.
This is the photo post on Tacoma World of when I did the chalk test, 10 years ago, when I first ran the Hankook Dynapro tires: https://www.tacomaworld.com/threads/chalk-test-dynapro-atm-a...
If you don't want to click the link and see the photos, here are the steps as I posted them:
Step 1, check that your tires are all at the pressure you assunme to be correct.
For my Dynapros, they all are at 37 psi. I have (by feel) determined 36-40 psi to be a good range for these 44 psi max. tires on my lightly loaded to
unloaded 4 door Tacoma.
Step 2, with big sidewalk chalk, make a one inch bar across the tread.
Step 3, drive for approx. 100 feet and then see how the chalk wears off.
If it wears mostly in the center, too much air. If more wears on the outsides, then too little air. If wears is even across the tire, you are gold!
OH, and after doing the test, I have lowered the psi to 35 on all 4... soon I will re-test and see if we have improved wear even-ness...
* a final adjustment to 34 psi was made, since I retired and no longer drive with a load of irrigation parts and tools.

My old post still stands the old BFGs great on my Turbo diesel Ram 50,000 plus. KO2s total crap history less then 20,000 miles Im needing new tires
now. Since the Ko2 anytime I see someone with them half ton 3/4 ton. Or suv. I ask how long they last all report shot at 20,000 miles or less. So lets
hear it on big truck 3/4 ton how long they last ? Not knocking handling BFG only short life no go for me

Chalk test is pure garbage. Tire mfgs publish load inflation tables for a reason. Figure out your axle weight, look up the appropriate tire
pressure.
If tire tread is differentially worn, chalk test does not account for differential wear.
If tire is stiff, like most LT tires, then low air pressure may result in false positive.
Why run a chalk test when the mfgs publish tables telling you correct air pressure for your load?
It is much less effort to look up tire pressure in a table than it is to do “test”

Agree with Goat. Never ever did a chalk test Never had uneven wear because I use the tire company pressure vs weight chart.
Yes I have adjusted pressure for varying weight for the truck and I adjust the pressure for my off road use as well

I have 2 tire pressures: one for empty vehicle, and one for max towing/loaded. Worrying about gradations between empty and max load is not worth the
time and effort.
