Thanks. Added sliders a week ago and it rounded out the overall look! Almost time to start using the new additions, can’t wait.

My $0.02.

I always like the idea of having 255/75R17 on the 4runner, so couple of years ago (at that point I had 4th gen (4x4, V8) I switched from P265/70R17 Nitto TG gen1. to Copper AT3 255/75R17…

I only had them for about 10 days and went back to P265/70R17 Nitto TG gen2.

The main reason was the lateral stability of the 4Runner… with P265/70R17 Nitto TG the truck felt great (for body on the frame SUV) in any turn taking at a reasonable speed…. with Copper AT3 255/75R17 I felt my suspension \tire is collapsing at every turn… the unsafe filling and lean in turns were not acceptable to me… and I have tried played with air pressure with no meaningful changes…

I know I am not comparing apples to apples here (Nitto to Copper) and possibly the biggest contributor to a poor lateral stability was very weak sidewall of the Copper… but I thought I would share my experience.

Thanks for posting this. The chart really puts it into perspective. Maybe it’s just the pictures that were throwing my eyes then because the difference is pretty marginal.

So @Jetboy posted about this in the previous pizza cutter thread.

The tall skinny tire will "squish" more at the same psi as the wider tire because both tires will create the same square inch footprint at the same psi with the same vehicle weight. The fatter tire will have a wider footprint and the skinny tire will have a long footprint.

Because of that the tall skinny tire will be compressed more vertically and have less ground clearance under the axle.

So really the only advantage of the pizza cutters is better highway fuel mileage.

you have a gift for filling this forum with nonsense

Excuse me? The hell are you talking about?

I am just paraphrasing what @Jetboy said about this in the last thread about "pizza cutter" tires.

Have at it:

Anyone running 255/80/17 Tires Pizza Cutters

I'm familiar with the thread.
To say that this is the only advantage is wrong.

please consider,

Less rubbing problems-- many people run 255/80 coopers with no rubbing at all.
less rolling mass: less unsprung weight, less reciprocating mass for shock dampening
less wind resistance
less turning radius scrub; less wear on bearing and steering components
less shit flinging down the side of your truck
less cost

More MPG from items 2 and 3 items above.

Less friends on instagram I suppose.

I don't have a dog in the fight. I was simply sharing some interesting information from the other thread that this one is essentially duplicating. Go argue with those guys if you want.


^ This is the part I want you to address.

Maybe not everyone is trying to use their vehicle as a way to compensate for "toughness."

The way I understand it, is that skinny tires are far better in snow, sand and loose rocky situations. The idea is that you have more psi on the tread of your tire the more narrow you go. Who cares how it looks as long as it performs. I understand that aesthetics are important to people but I like the way the narrow tires look. In fact, to me it makes you look like you know what you are doing.

By that logic you'd get better traction not airing down and in fact would do better to run really high pressure to get more psi to the ground via smaller tire footprint. In reality that doesn't help.

Maybe not in mud or on massive boulders where you want your tread to touch as much uneven surface as possible. Airing down also helps with cushioning the blow when you run a little faster in 4HI. But in the situations I mentioned previously, wide tires don't work well. Tread pattern is also important for specific scenarios. If you are just on dirt single track type roads, im going with the skinnies all day.

You're saying wide tires don't work well in sand and snow?

This is all correct. It doesn't take a leap of faith or logic to reach the conclusion that - all else equal - wider tires = better offroad performance. There's a reason road bike tires don't look like mountain bike tires.

What needs to be recognized is that it's rarely a trade off between equal height tires. Usually given a vehicles drivetrain (power, gearing, axle strength), the choice is between a taller narrower tire or a shorter wider one. In that instance, the taller tire can often be a better option for certain types of use. A taller narrower tire is often a better choice in soft terrain than a shorter wider one. But not better than an equally tall wide one - assuming you have the power to push them.

I chose taller narrower tire over a shorter wider one in my last purchase. Although relatively similar in size I chose a 34x11.4 (285/75) over 33.4x11.9 (295/70). I agree that the two are pretty similar in fitment requirements for a 4runner, one is about half an inch taller, and one is half an inch wider. As between those options, I personally chose the taller narrower one because I think it'll be better for my use. Had there been a 35x10.5 tire in something not made by interco (I love me some interco tires - but not for a dial driver) I probably would have gone even taller an narrower.

BUT... that doesn't mean a 35x10.5 would be better than a 35x12.5 if they both fit. The 12.5 would be better in practically every offroad function.

And the narrower tire is often better for highway use as well. Taller narrower tires have lower rolling resistance and lower wind resistance. For mixed use it's often a better choice.

Finally, narrower tires are not better on snow or ice in almost any situation. Icelandic trucks look like they do for a reason. Those who speak should do. Those who do should speak. People who favor narrow tires on snow and ice have rarely ever used them on snow and ice. People who drive on snow and ice quickly learn that wider is better. The exceptions to the general rule are for highway driving scenarios - not off road. In slush for example a tire that doesn't hydroplane will be a better option, so a narrower tire may be preferable on slushy highways for example, just like a narrow tire will often be better in the rain to resist hydroplaning. But the narrow tire would not perform as well on a muddy road - unless the mud is only a few inches deep with sold soil underneath. So if your driving is primarily highway use and you occasionally encounter an unplowed road, or thin layer of mud on a logging road, narrow tire might work just as well for you without the highway penalty of wider tires. But if you're comparing which tire will be better for 3 feet of snow - it's not really even a question. Wider tire with lower ground pressure wins every time.

This. Anyone ever use a snowshoe?
