Hi @gaijin. What would the recommended tire pressure be for a BFG KO2 285/70/R17C 116/113Q on a 2008 LC200?
Yes Thank you!That would be the LT285/70R17 Load Range C 116/113Q tire, correct?
If so, the RCTIP (Recommended Cold* Tire Inflation Pressure) for those LT285/70R17 tires on your LC200 is 39psi Front / 41psi Rear.
* According to Toyota:
Tire Pressure vs. Tire Temperature
Tire temperature is dependent on “cold” tire pressure, driving distance and speed, ambient temperature and road surface temperature. As the temperature of the tire changes, air in the tire expands and contracts, changing the tire’s air pressure. The cold tire pressure for all Toyota models will vary and will need to be adjusted accordingly.
“Cold” tire pressure, as shown on the tire pressure label on our vehicles, is generally considered to be the pressure in a tire that has not been driven in the past 4 hours and has been parked outdoors.

Hi Gaijin, needed tyre pressure recommendation for the lx600 luxury with ahc.
Wheels 18" OE black edition and tires continental terrain contact ht 265/70/18 SL
Thanks in advance
I'm actually 90%+ highway, 175 miles around the bottom of Lake Michigan to O'Hare. Mostly dry and 75mph. The few times I'm running in challenging conditions, these tires have been amazing in slush and snow. As heavy as these tires are, I suspect they can handle this lower pressure without heating or internal layers breaking down. There is no perceptible sag with that pressure change.^ yep, real-world use case is the best method for tire pressures. There is no one set best pressure for all brands, all weights, all conditions. The only caution would be shoulder wear from that pressure, but with those being snow tires and the amount of white roads you travel your treadwear on those will be very low. And I would much rather shave a few percents off the life of the tire than be in the ditch. My guess is at 35 you're still well within the load limit, but would be wise to double-check the inflation tables.
This is the first year we've gone from 3PMS to a true winter tire. Running studded Hakkapeliitta 10 on the Yukon XL and are very impressed. If it were deep snow I'd still prefer a floatation sized AT3W/AT4W but for highway use the Nokian is very competent.
Not sure if this is right thread to post or not; but I’m wondering what’s the safest/ lowest tire pressure I can run on my factory wheel and ko2 tire 285/55/R20 (load D) for heavy trail riding without fear of breaking bead? Stock weight. Currently running ~25 psi off-road and 38psi on-road. Thanks in advance!

Not my damage per say, but saved a buddy from not 1, 2, but 3 tire failures this weekend. 1 tire absolutely destroyed. 2 tires just popped beads that the LX dual Viair OBA was able to re-seat. Of course the popped beads happened in a pinch where he simultaneously lost both rear tires and was outright stuck on sliders.
Where this is relevant for the 200-series is probably the LX that has similar stock 20x8.5 wheels sizes to the F150.
PSA - don't run a 275 width lower profile tires on a tall wide wheel, as many LX owners seem to do. Namely a 275/55R20 on an 8.5" width wheel. At 20PSI, tires failed all too easily. IMO, needs more sidewall height either by taller diameter tires or smaller diameter wheels. Also, poor mans beadlock is a thing, and for a 8.5" wide rim, really need 285s or wider.

Exactly the information I was seeking! And that is the exact scenario I’m trying to avoid. I have a feeling after these tires, I’ll be upgrading wheels. I just love the stock lookSorry for the late reply but playing catchup this week. The pressures your suggesting are about right. I would be cautious to go much lower from an experience with a buddies rig on the trail. It's one of the factors to why I recommend wider rubber.
Checking my assumptions, your setup is a 285/55R20 KO2 on a factory 20x8.5" wheels. Recommended wheel width for this tire size is 8 - 10". Generally for airing down and bead retention, you really want to be on the upper end of wheel width for a tire. Losing a bead can be a very real liability as you'll see.
My buddy ran a 275/55R20 KO2 on a 20x8" wheel. Recommended wheel width in that size is 7.5- 9.5". So similarly within .5" of the lower end of spec. We literally lost 3 tires off the bead in a matter of a couple miles. One tire completely destroyed doing a mild turn at speed. Fortunately we were able to get the bead back on the other two wheels when losing them over a technical pinch obstacle as he had no more spare at that point. He was running 20psi.
Here's more of the backstory
