LT Load Range E Tire on 4Runner

Overkill for a 4Runner. Great price for that tire. I have E-rated tires on my F250. You will notice a stiffer ride.

+1 I have them on me Dodge diesel. When I upgraded to E rated tires I could feel the ride become stiffer. My truck weighs almost 9k pounds. Unless you are rock crawling, you don't really need E rated. But if it is a great deal, then go ahead and give it a shot.
 
I guess it will improve handling and cornering.

It would depend on suspension as well. I would not buy E load for the 4R but they do not feel punishing on road on my friend's GX470, which is heavier and has a more plush suspension.

When I had D-load KO2s on my H6 Outback, I loved the handling due to the stiff sidewalls and they also helped offset the 2.5" total lift (2+0.5 from tires) whereas my city tires, P--metric Geolander ATS were awful in comparison. I had upgraded brakes and never felt their weight when braking.

The ONE performance issue with tires made for much heavier vehicles is that if you run the street pressures tire makers recommend (email them and they will calculate it for you) when converting from P to LT, you end up with very high pressures and if the vehicle is empty, you may literally have too little contact patch.

The reason I never ran the KO2 in town, in addition to preserving them for trips, was that they rode terrible on an empty vehicle. If you air them down to the P metric pressures, you lose capacity and you may wear them faster as well though that depends. And they are still not that comfortable.

The other issue with D/E is that they force you to air down not just when needed, but also for any dirt road or the ride is unbearable.

And of course D/E tax the powertrain so that's another reason a GX470 may find them just fine whereas a V6 4R may feel sluggish.

You'll have less potential issues with blowouts or piercings due to gravel roads (rough gravel roads) and other surfaces not considered usable to Subaru vehicles...

Excellent tires though...they are much heavier so you will have a small decrease in MPG...but one doesn't buy these rigs for efficiencies, right?!

That's true on average.

But it is not necessarily true in every case. Unless you drive on the sidewalls or drive all the time in the desert, the E-load won't provide any strength advantage over a good P metric or C load tire. Lots of people lose tires and complain on the internet because they aired down too much unnecessarily.

Next, it depends on the tire. For tires known for punctures, like the Cooper Discoverer AT, going E makes more sense than for tires that do quite well in P like the Falken Wildpeak.

Considered suitable for Subaru is indeed the correct word choice :) . We have driven a few dozen 4wd trails not considered suitable and that's why I had the KO2s--I did not want to worry about tires at all.

They have the same tire in P load (SL) for even cheaper. If you mainly drive on roads and some dirt roads every once in a while these might be more comfortable and you save some weight. The also have a 255/75/17 in P load if you want a slightly taller tire, although that one is a bit more expensive.

There is only 1 tire left in stock.
 
I have E-rated tires. You can find pretty much two completely opposing pieces
of advice about any tire-related subject on the internet, so good luck trying to come away confident in the information you get.

First, the ride is stiffer than P-rated, or non-E-rated LT, since the sidewall is stiffer, and therefore has less flex. The weight difference over P-rated is significant, and will really hurt MPG, but comparing E-rated to C-rated tire weight and you'll see the difference is minimal, because it's just a few extra sidewall plys.

You can air up much higher, which allows you to carry heavier loads, but the amount of weight you'd have to be carrying for that to matter over C-rated is beyond the capability of your vehicle.

You also can't air them down as much as tires with softer sidewall, because it can put too much stress on the less flexible sidewall to be bearing more of the weight.

I'd suggest starting with this: Understanding Tire Load Ratings
 
If you are towing anything heavy with a V8 model, the load range E may be beneficial... since the V8 has a higher tow capacity.

As to the mention of the cooper tires by MAST4R, I agree that they puncture easily... not just the A/T. I'm running Discoverer HTP and they certainly seem to be slightly magnetic.
 
I run E's on my 06, and in general I like them ... they are noticeably stiffer, but not bad if running proper air pressure. There are pros and cons to any tire. Is it worth the extra weight, lower MPG, etc? Truthfully, only you can decide.
 
id suspect a good proportion of ppl would sacrifice some ride quality for assurance that they wont get a flat, especially those who offroad regularly.

while on the subject: i have brand new KUMHO at51 LT255/75/17/6ply/108R getting installed in the next
couple weeks. how come they advertise them as LT and 6ply with 108r? ideally id have something between LT load E and the soft P or whatever...is that kind of what i got with those or?

How did they affect your MPG?

There is no promise of no flats with E load. And the plies is just a rating, not like you actually have 6 or 8 or 10 plies! An E still has 2 or 3 plies sidewall but they are thicker plies. I would also get an E on a trailer king (built rock crawler), but for a normal vehicle, it is really meant for towing and heavy vehicles.

I use weight as an approximate indicator of strength within one and the same class but some tires are as strong in P as in LTC like mine, per the email I got from Falken.

And your 275 70 17 AT51 weighs the same as my P metric Falken Wildpeak. The 275 70 17 Wildpeak is 10lb heavier than the Kumho.

Soft is good for offroading, actually, both for traction and comfort. It is not like "soft" means "bad." But you may like a bit of a stiffer sidewall on road as the 4R will corner and handle better with stiffer sidewalls.

Anyway, the Kumho should be nice all around tires.

thanks - mine are 255 75 17, but good to know about my tires, i thought since they are labelled LT that was always load E, but im pretty sure mine arent load E. is the 108R indicative of the load? what load are mine? P S R E?

Well, the problem is that most LTs are Es but thankfully not all.

The Kumho table does not label the 255 75 17 for whatever reason but the maximum psi is only 50 which indicates it is an LT-C.

ROAD VENTURE AT51 - ALL-TERRAIN LIGHT TRUCK/SUV/CUV | BETTER ALWAYS KUMHO TIRE USA

EDIT: yes, the numbers are the load. Mine are noticeably higher though mine are P metric. Not sure you want to tow heavy loads with those. But the letters are the speed, not the load.

SO: speed: R, S, T, V
load: 108, 113, 115
type: P, LT-C, LT-D, LT-E

I'm running E, but only because it's the only rating available for the tire and size I wanted

Ride is firmer but not terrible. My only issue with it is how little the footprint changes when aired down. We'll see how much that changes as they break in and that will decide if I choose a lower-rated sidewall for my next tire
 
thanks!! you possibly confirmed exactly what i was thinking when buying them (i wanted that tire size, at, and mid grade load or w.e. and free shipping new from amazon $155 each, hell yah)

OP i bet you will enjoy your tires regardless knowing they are strong and you got a good deal!
