Yes, I know, do a forum search - that's what I've been doing for over a week know, and I'm still not sure what to get.

I'm placing an order for Dueler Revo 2 A/T tires today from costco (70 bucks off set of 4). I'm want to get them ASAP because of two things - my dunflops have no tread left on them (dangerous to drive) and second, I have my daystar spacer lift and wheel spacers ready to go, so I want to to all of it in one shot.

I'm getting 265/70R17 tires. About 10-15 times a year I'll do some light to moderate off-roading. Other than a short daily work commute, I mainly use my runner for road trips (camping, skiing, etc). 90% of the time the 4runner is on streets, but in mixed conditions (dry,wet, slush, snow, etc), but when I see an off-road option, I'm more than happy to take it.

It boils down to this...P or LT (Ps weight at 41bs, LTs and 47). I never had an LT tire, but I'm OK with harsher and nosier LT tires. Logically P tire make sense, but having an LT ones would make me much more comfortable for longer tips and those rare time that I go off-raoading (I'm planning to dump Xreas and get a proper lift in few years). But I guess my biggest concern is air pressure. There are so many different opinions out there that I don't know what to run (as low as 35psi to as high as 44psi). On top of that Costco's filling them with nitrogen. If I go LT should I just ask them to put air and then adjust it to what I like?

Help out a nub thanks

The LTs are intended for towing and carring more weight. Yes they may be a little better for off-roading but for easy off-roading they are not needed. Just remember you may lose a mpg (or two) because of the extra weight/size.

I would go with P rated. I have them and I tow and do light off-roading and they are great.
IMHO and for my use of the 4Runner extra noise and harsh ride with LT was not worth it..

Yeah, going P. LT is a nice idea...but that's about it (in my case)
At what PSI are your Revos?

The pros of on are the cons of the other.

"P" series pros:
softer sidewall and tread belts- a smoother ride
lighter- better acceleration, gas mileage and braking
less expensive

"LT" series pros:
the tread depth is ~2x as deep when new- better traction and longer life
stronger sidewall and tread belts- better puncture resistance on trails
firmer sidewall and tread belts- a firmer/controlled ride on road
firmer sidewall and tread belts- less squirm when carrying loads and towing

Note: The LTs will have a max pressure on the sidewall. most people will want to run them at the same pressure that the stock "P" tires run. The max pressure is to carry the max weight rated on the tire.

Not much to add except the tread depth difference is nowhere near 2x. In the case of the Revo 2 the LT tread is 25% deeper. I don't think I've ever seen a difference that went past 50%.

Despite the shallower tread, tire companies often restrict mileage warranties to the P-metric tire only.

The LTs do not ride much different then the "P" tire (unless using max pressure). Max pressure for the "P" is 44psi and 80psi for the LTs. Also the thread depth is only a couple 32nd deeper on the LTs. The "P" come with a 5 year/50K mile warrany and the LT has none. LTs will hit the mileage.

If you only do easy off-roading (not much rocky roads) there is no need for LTs. I recommend the "p" tires. If mileage is a concern I would stay with the 65s. 70s are thinner, heavier and will change the center of mass, causing less mileage. The 65s will provide a little (not much) better handling at highway speeds. If you go with the 70s you may want to have the alignment checked after the install.

35 PSI for all, I am running stock size 265\65R17

I am not sure what you meant by “thinner”… 70's will have larger radius by ~13 millimeters vs. 65, so they will be “taller”....
Also, IMHO you will feel a big deference in ride quality between LT and P even with the same air pressure.

This may come as a shock but 65s are the better on-road ride. The ONLY advantage a 70 series tire has is adding a 1/2 inch of ground clearance. 65 series tires have more tread (wider) on the ground then 70s. Here's another shocker, I have found that 40 psi is the perfect psi for "P" tires (on 4WD light trucks) and 60 to 65 is best for LTs. LTs are constructed differently than "P' tires and need more pressure. These pressures provide the best handling/mileage and wears just like the recommended pressure. Try these pressures before the flames.

How do you figure that a 65 series is wider than a 70?

A 265/65Rwhatever is the same width as a 265/70Rwhatever. The difference in the two tires (ceteris paribus) will be the side wall height. The side wall of a 265/65 will be 65% of the 265 and the 265/70 will be 70% of the 265, resulting in a taller sidewall.

The 65 has 8.1" of tread width and the 70 has 7.8".

Off hand I can think of two. More load reserve and probably cheaper. Currently, In fact, it's $84 cheaper for a set of four 265/70/17 Revo 2s at Tire Rack.

I went with P Revo 2s.
P265/70R17, 5 tires, $1150 Canadian total (with installation & 13% tax)
There's a rebate in Costco, 25$ off per tire on any Bridgestone, and 70 off on 4 Pirellis.

Congrats. I think you'll love 'em.
