Where did you find a spec chart on their site?

Just received this response after reaching out to BFG... I asked (they knew it was a 2014 GMC Sierra from the questionnaire): I just put BFG KO2s 275/55/20's on my truck and have no idea what PSI to go with. My truck is the 4WD Crew Cab Short Bed, I am currently running them @ 39 in the front and 37 in the back cold (compared to the 32 PSI my stock P tires called for) and they still feel kind of flat. Any suggestions? They answered: Drew, I will be happy to assist you. When installing a different size than the original equipment tire, all vehicle manufacturer specifications must be maintained. The replacement tire should be inflated to provide the same load capability of the original tire size at the manufacturer’s recommended pressure. The original tire size can hold 2,105 lbs at 32 psi. The new tire will need to meet or exceed the weight. We recommend that the new All-Terrain KO2 LT275/55R20 use 50 psi to hold 2,270 lbs.

Sincerely, Natasha Consumer Care Department Certified BFGoodrich Product Expert Looks like I will be going up to 48-50PSI today after work!

Just picked it up, had them go with stock 275/55/20 sizes and 40 psi front 38 psi rear. Is it weird that coming from stock SR-A tires the KO2s feel flat? Should I jack up the PSI? It just feels really slow/grippy off the line and harder to turn, also a noticeable sound increase at cruising speed.

hey guys, i have the shop putting these on today around noon. from what i've read, im thinking blackwalls out and 40 PSI front 36 PSI rear cold?

Haha darnit fondupot, I've been very pleased with my Duel Can setup but now I'm tempted to toss a second evacuation port on the cans!

Mine does it when its cold and if its wet out.

Condensation holds MUCH more liquid than humidity. When its cold and your engine is much warmer than the air around it, condensation forms.

Yea, I think the final model is complete. He just drafted up an adjustable leg for the bottom support on the can last week so I think after I toss that on, update the product overview - it's good to go.

3/8" can(s) designed for our truck's: http://www.gm-trucks.com/forums/topic/170204-official-saikou-michi-dual-oil-catch-can-review-model-s1-gm53-ds/

No worries, I always drain after the trucks been driving at full operating temp for a while to avoid anything like that.

I started a thread on the Saikou Michi cans, half the price of an RX, performs just as good, brackets are designed for our engine bays, holds a good 10 ounces. Ask for a single can system and you'll be in your price range, add another 50-60 bucks and you can get a dual system.

Man I totally forgot about that stuff, I know some other places I can definitely us it! In regards to heat and the CC, I personally am fine with just leaving it in the spare battery location. If I had a car with CC, then I may possibly look into material to reduce heat. Only thing I've added to the system because of possible heat issues was I wrapped all the hoses in split plastic conduit to stop them from touching each other and other hoses.

I agree and obviously I'm just going off what I read but if you google Thermal Mapping of Truck Engine Compartments, you will actually see that those front (and rear) corners of the engine bay are significantly cooler than that areas people have been mounting their cans right next to the engine blocks.
