OK - I did a couple of searches and found some info but not just what I was looking for.

I have a 2006 Nissan Frontier V6 4x4 manual 6 speed. The factory plate shows 265-70-16 tires as stock tire size & suggested tire pressure 35 psi.

What I'm looking for is what tire size came stock on the Pro 4X - 2005 year- and what did the factory plate call for as suggested tire pressure. As a starting point. Did they even change the tire pressure plate from the non Pro4X to the Pro4x????

My new to me 2006 came with different wheels and tires - 265-75-16's E range and the guy I bought it from was trying to make it into a PRO 4X - kept talking about the 4X as a selling point. He changed out the shocks to comparable (he says) to the Pro4X & the tires/rims.

I did a tire comparison and found them to be the same width and the "75" about 1 inch taller. Not a lot of difference but 1" taller does take some measure more of air and does make the gearing a bit taller although I haven't gotten around to figuring that out yet.

Just curious.

Thanks - LBM

35 psi for both 70 and 75.

Takes no more pressure at all, but it does take more volume of air the pressure is still the same...

BUT with that being said these trucks came with P-Metric tires not LT load range E tires. The factory P-Metrics rated air pressure was 35 psi but that LT tire might be better suited with 45 psi depending on load and/or towing etc...

Thanks - I guess I should of said volume other then some measure more of air but basically we are talking the same. So you are saying the fancy Pro4X comes with the same tires as the regular frontier??? I was expecting them to be larger and probably a 6 or 8 ply rated at least. Must just be badging and a bigger price tag that makes the Pro4X different.

I had to go to town for grocery's so I set the tires to 40 psi - checking with 3 gauges to see if they would match - close enough. I picked up a white tire crayon while in town just before I headed back. Marked about 10-12 lines across the tread and on the side to show where I marked. When I hit the dirt @ about 35 miles of hiway. All the white was worn off the tread on the front and back so I'd guess 40 psi is where I'll run them for now.

So I guess the Pro4X plate is about the same as the standard 4x4 Frontier.

Thanks.

Nope the P4X just gets a P-Metric All Terrain tire with a little higher load capacity... My SV came with 265/70R16 (30.6") all season tires rated at 2,403 and the P4X came with 265/75R16 (31.6") all terrain tires rated at 2,610 pounds...

The P4X gets a better stronger rear end with an electronic locker whereas the SV comes with a smaller lighter rear end, splash (AKA skid) plates and a marginally better set of shocks but beyond that the trucks are pretty much the same...

LT tires typically need more PSI to carry the same load compared to a P tire; not unusual to go from 35 psi in P to 40-55 psi in LT.

The thicker sidewalls in the LT tires are going to heat up faster and retain heat longer than more flexible P tires if you underinflate them. They're designed to ride stiffer for various reasons. Airing down isn't usually a problem for people that are using them offroad at low speeds and want the thicker sidewalls for cut resistance.

A note on the stock Pro4X Hankooks - I have a lot of miles on mine aired down offroad on rocks. There are about 2 dozen small nicks (1mm x 3mm on average) in the sidewall showing white rubber on each tire, but I have never had a sidewall puncture. Did have one sharp rock puncture the tread on pavement, though.

I wouldn't hesitate to take them offroad as long as you air them down to about ~24-20 psi hot, depending on whether you're carrying a lot of weight (higher psi for more load). They are good tires.

By stronger rear end are you talking a Dana 226 vs a C200K? Mine has a R180 Front and a Dana 226 rear. No posi locker though. LBM

My 2015 Desert Runner came new off the showroom floor with the Hankook AT-M 265/75R16 and also with the nicer rims too. Not just a Pro4x thing..

Yes I failed to notice that you said 6-Speed in your opening post, oddly enough Nissan used the stronger Dana rear end without the electronic locker on the 6-speed SV and with the electronic locker on the Pro-4X in both manual and auto transmission variants...

The Hankook AT-M RF-10 tires are available in both P-Metric as well as LT variants, but Nissan never used the LT variants as their heavier carcass tends to reduce MPG and can reduce ride quality...

Yep the DR got caught playing dress up in its big brothers closet and escaped with the tire/wheel package, shocks, splash plates and a few other cosmetic items... I'm told the earlier model DR were sometimes found with Pro-2X sticker packages too... At one time they too might have gotten the Dana rear end but I'm not clear on that one...

The stock Pro4x RF10's are indeed the P versions.

I'm really torn on whether to move to an LT tire, because the stock tires have proven their durability for my uses and they're only 39 lbs apiece.


The only thing I don't like about them is that on steep logging roads with wet snow they won't dig down to the gravel very well. If it's really cold, they'll float right over and grip fine, though.

The Nismo/p4x comes with lower gearing to account for the taller tire.

Most P metric tires have a higher load rating than an LTC.

35psi on the stock tires was too much. My stockers ballooned at that pressure wearing out the centers more than the sides.

... The Nismo/p4x comes with lower gearing to account for the taller tire...

Do they? The info below I clipped out of a PFD I found called "2016 NISSAN FRONTIER CREW CAB SPECIFICATIONS" this would lead one to believe that the only difference in ring gears was between the auto or manual options...

3.537 – 6MT 4x2
3.133 – 5AT 4x2

3.692 – 6MT 4x4
3.357 – 5AT 4x4
