255/75/17 KO2 Pizza Cutters

[1jzgte]

I'm running 255 Blizzaks for that winter tough look.

I'm swapping to Michelin LTX 255-75-17 after these Dueler Alenza Plus's
wear down. Yes boring simple functional tires that do their job too damn well.

I agree with the utility in the skinny tires, but with the huge weight of our runners they can be pretty scary during evasive maneuvers while at speed.

Hmmmm. You might have a valid point there.

I have been debating between 275/70/17 and 255/75/17. Was leaning towards the 255 due to the lighter weight and larger selection of tires. I'm not overly concerned about off road performance since taller and thinner can sometimes be better than fatter and lower and visa versa, depending on the situation.

However, ON road I think I would prefer to be on 275's during evasive maneuvers.

I think a 265/75, 265/80, or 275/75 would be awesome tire choices. How come there are no tires in that size?! With a 17" rim of course. I know the 265/75/16 exists.

 

[Decipher]

Agreed.



Form < function.

I knew I’d kick the beehive with my comment but it’s true.

People don’t do this because it looks ridiculous. I am typically a function over form kind of guy but not in this case. I want both. I’m sure they perform well off road except perhaps in sand and I would think mud.

I do more off roading than any of my friends and have never once been in a spot where I wished I had a more narrow tire.

To each their own. Love the look from the side! Do what makes you happy...just not for me or most.

Plus you get less rubber to protect your wheels. I just can’t understand the benefit other than, of course, weight, MPG, and cost savings.

I’m running the 255/75R17 KMs from a stock rubicon. OME light kit and spidertrax.

Nice looking rig! The spacers help the look.

At least you get better options if you’re not interesting in just E range tires. I off road but I don’t crawl rock and really don’t need the overkill E range so I see this option opens some doors with that.

255's are roughly .45 inch taller from the curb; i think its invalid that wider tires provide better wheel protection from off roading.

I feel like most speedometers read 1.5 to 2 mph too fast; so this taller tire will keep things more accurate at the speedo. This also means you'll accumulate fewer miles on our 4runners thus helping resale value.

Then again, these changes are so small that no1 would even notice any changes except in vehicles handlig behavior

I had the 275/70/17 KO2's for a couple years. When I got new tires, I went with 255/75 in load range C.
The difference in ride quality is night and day! The truck feels 1000 lbs lighter and it has more grip now. The old ones still looked new with a lot of tread, but seemed laborious to drive and added a lot of drag I could really feel when I let off the gas. Also, wet traction on the road was horrible.

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 [MENTION=118321]Jetboy[/MENTION] 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.

Excuse me? The hell are you talking about?

I am just paraphrasing what [MENTION=118321]Jetboy[/MENTION] said about this in the last thread about "pizza cutter" tires.

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.

 

[damthemainstream]

Because, quite frankly, it looks ridiculous to me.

I’m not criticizing those who are doing it. Life’s too short to be unhappy. I just can’t get over how bad the slim width looks and I think a lot of people feel that way which is why a lot of people upsize their offsets or do wheel spacers.

From the side, cool. From every other angle it looks awkward and not tough.

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. :deadhorse:
