Elevation, unless you’ve got wings on that Talon Wasabi......
HAHA That’s what happens when I don’t get enough coffee before posting!
Although... My Talon has gotten some air.

Which tires did you go with? Love to hear what you think after you have some seat time with them. Thanks
I enjoyed the discussions too! I think the confusion came from mixing oxygen content and pressure altitude. A manifold pressure gauge (intake) will read around 30" at sea level, with the engine off. That pressure decreases as you gain altitude. The air is thinner. Airplanes with turbochargers / turbo normalized , can deliver sea level pressure up to a certain altitude based on boost. Above that the horse power declines. Just as it does in our Talons, cars and trucks.
The cabins in pressurized aircraft can maintain sea level pressure up to certain altitudes, but in the 30,000 ft levels, depending on the aircraft, the cabin pressure is at about 8500' level. All they are doing is bringing in outside air and pressurizing the cabin to what ever the aircraft is designed to, perhaps as high as 9 psi.

I mounted 32x10x15 Tusk Terrabite radials on STI HD9's. I have the 6+1 offset up front and the 4+3 in the rear. Track width is very close with no need for spacers.
I've only gotten to try them on the street in my neighborhood, not on the trail yet so I'll try to update when I've logged some trail miles on them.
I will be interested if you have any trouble with keeping air in the tires. Are they the light weight Kevlar or?
Love the wheels. If I had seen those before I bought mine, I would have liked to try them.
Thanks.
The tires are the radial, not the Aramid Kevlar version. I was about to reply that after being aired up for over a week, they've not lost any air although it hasn't been trail ridden yet. I decided to check actual pressures and it seems one is holding the same amount I initially aired them up to (16psi) and 3 of them are at 14.5psi. So they've lost 1.5 psi over the course of less than 2 weeks. It's something I'll have to keep an eye on and glad your post resulted in me actually checking instead of saying "they look ok"!
Is your width more or less the same as stock?
I have an x but I believe the wheels are the same, and I'd like to not go too much wider. I was hoping the common 5+2 all around would keep me about the same in the rear and maybe a little wider in the front.
The end result is a little bit wider. My actual measurements are as follows...
Stock front wheels and tires the outer sidewall to outer sidewall on the front measured 62 3/4" and the rear was 68"
With the STI wheels the front outer sidewall to outer sidewall now measures 69" and the rear is at 70"
I also believe the wheels on the X are the same but don't know if the track width is different from the R.
Member @PaulF has some really good info that he's shared in this post that helped me decide what wheel combo to go with.
Talon - Tusk Terrabite 30x10x15
I'm sorry, but there is no way you gained 6 1/4" of width in the front with . I'm guessing that's a typo.
You're probably right, I don't have the tires mounted on the stock wheels to double check, it's what I wrote down but it wouldn't be the first time my brain and body miscommunicate. According to PaulF's post the STI 6+1 offset in front should result in a 1.3" wider width overall. I just double checked and my STI 6+1 fronts are 69" wide. What's the stock X's front width measure?
64 inches. But that 1.3 will be at the rim outside edge. Run a 10 inch wide tire on 7 inch wide rim and you can stack 3 more inches to that.

hum do i respond to the air pressure, boost, oxygen part of this thread, or the tires portion of it.
I live in AZ, at 7000 ft. i have 32, is it a little slower? maybe. if i were racing it i'd be running 30's but i'm not, and you'd need a stop watch to see the difference from the 28 to the 32's its really not that bog of a deal. i ride from 12K to seal level and the machine does just fine with the 32's.
as for the pissing match over all the oxygen and pre4ssures and what not, really? like get over it, agree to disagree. why have a argument on here for that? brought down the thread. should have stayed to tires.
IMO!!!

I made a whole thread on this, as not to clutter up a bunch of other threads. But no, a 6+1 should actually be a hair narrower sine the stock fronts are basically a 5.25+1.25. Adding a 10" tire probably negates that, but it should not be 4-5" wider by any means.

haha it’s funny you see the discussions on oxygen and pressures as a “big thing” it all happened 2 weeks ago.
Everyone who participated is over it. (Except you)
thanks for your input on 32’s.
Ah yeah. The offset thing always gets me. Then outside of tire would be the most at 3 inches. Unless he put spacers but i didnt see any mention in that above.

Just a first impression, got about 120 miles total today. Not as nimble as the stock set up, but turns well and the extra ground clearance is welcome. I temporarily put the wheels from my Teryx (29x10-15 ITP Ultracross') on my Talon and they understeered and wallowed badly, none of that with the Terrabites on the HD9's.
Started out at 14psi (20 miles of pavement), lowered to 12 on the gravel but still felt a little skittish. Lowered to 9psi in the rocks, had my buddy on his bike looking at the deflection, he says it was minimal.
These tires are much stiffer than the stock tires, so depending on the terrain, I'll be running 8-10psi. I'd be comfortable running lower if I'm rock crawling. There's some fast 2 track stuff that I sometimes ride that should give me good steering feedback, I'll try to get out there next week.
Here's a portion of what we rode today...
