E Rated Toyo tires?

Rocks are the deal for me, especially sharp ones. I don't need 80 PSI, I need something that isn't going to get cut to ribbons.

 

the stronger construction of an E rated tire is going to ensure it doesn’t get sliced. The extra durability for the weight capacity is what lends itself to its off-road durability.

Ignore the psi rating on the side of the tire. That’s max pressure. It’s irrelevant to the 4Runner application.
The construction and composition of the tire is what you are looking for.

Or buy an SL and get good at changing tires in unfortunate circumstances.

 

For those that need it.

if random information on the internet is to be trusted:

there would be no need to select a pressure that exceeds the max axle capacity, running an E rated tire.

 

I know, I was just answering the question as asked. I honestly don't think the max PSI is really that relevant.

 

oops, my bad!

 

I cannot really compare since I never drove mine with the factory tires (I had stock size Toyo AT3's in load range E put on before I picked it up). I do not find it harsh at all...but I also came from an F150 running 33's on 20's (it came with them). They *can* run 80psi but unless you needed that load carrying capacity (or do not understand that Max pressure does not mean that is what you run them at), you would never run them there. I run 42-44psi in mine (your size is different so the required pressure will be too).

 

Well, today went to crap - so I didn't get to do much experimenting with pressures as I had hoped. That'll have to wait for another day

Toyo AT3 in E's installed (OE Size). Had them set the pressure to 45psi to start, I'll go down from there (likely).


Initial impression: can tell they are heavier, but it is what it is. Notice it slightly in the steering and acceleration - which I expected. At 45psi, I feel cracks in the roadway a little bit more, along with our ample potholes. I only got about 8 miles on them after install, I'll put another 50ish on them tomorrow and get a better feel for them. After that, I'll try 42-43, 40ish, 38ish PSI for ride, road manners and chalk testing.

 

Since you are running stock size i would suggest 34 psi and work from there, just a suggestion.

 

There is absolutely no reason to run those high pressures in your new Toyo tires unless you are hauling a lot of weight! Again, the Toyo MTs I've run on my Jeep TJ for the past many years I run no more than 20 psi. At that pressure there is a barely visible bulge in the sidewalls under the Jeep's weight. For a stock 4Runner I think you need to run 35 psi or less for highway driving. Air down to no more than 20 psi for rough dirt roads where you are not driving fast.

 

35 psi is the minimum for these tires per Toyo. (In off road situations, I’d be fine going lower. On highway, too little pressure builds up heat and becomes a problem)

I’ll do some testing and figure out what works best. I’m not that concerned about it right now.

I have a plan and know how to proceed. Did the same thing on my truck, and past vehicles.

 

Recently bought my 24 TRD PRO and swapped them OEM Nittos for TOYOS Open Country RT Trail in 275/70/17 E Rated. I wanted the slight addition in clearance and get a good strong off-road tire.

Went back and forth between the Toyos and Falkens. Read all threads here and could not decide. I was freaking out going with E rated and the new Falkens Wildpeak AT4s come in C rate for 275s. Ordered both to compare at Discount tire. I was also concerned with the added weight. To my surprise when I got to DT we checked the specs and the C rated Wildpeaks were about 58 pounds while the E rated Toyos were 52 Pounds.

Since I found the Toyos much more aggressive and visually nicer, it was a no brainer for me. Not sure why the Wildpeaks are heavier being C rated, but that sealed the deal for me. Got me the Toyos OC RT Trail, lighter, stronger and visually more aggressive. The DT manager also told me Falkens are not even close to Toyo's quality. In his words, Totos are the Cadillacs of tires and only recently during pandemic the Falkens raised the prices to be closer to Toyos.

Now, on ride quality I felt like maybe a 5% less plush ride when compared to the OEM Nittos. One caveat though, mine is a TRD PRO and those Fox shocks make a HUGE difference. I know because my wife's 4Runner is an SR5 and I drove both back to back. It is night and day between the two suspensions. The SR5 is comfortable, but in the PRO you feel like riding in clouds.

So, maybe with the PROs an E rated tire is less of a problem then with the ORs and SR5s when talking about harsher ride. I am very please with the Toyos and would recommend them without doubt for anyone with a TRD PRO. I am running them at 37 to 38 psi.

 

Do you have any pics of your 4R with these tires?

I’m guessing you had no issues fitting them with no trimming or anything?

 

Here you go. Right after install. No issues fitting these. But again the PRO is a bit lifted when compared to the other trims.

 

Those look great! Thanks for posting pics and the initial ride report. I'd love to hear how these affect your gas mileage to once you get a feel for it.

I really like the RT Trail, originally that was the one that I wanted to go with. I just think it may be a little more aggressive than what I need with the miles I put on, and also I would prefer something three peak snow rated.

 

Aired down to 40 today, smoothed up the ride a bit. Going to try 37 next. Don’t plan on going lower than that.

Barely any road noise, wet road handling was great today with a ton of rain.

 

LT requires more pressure to carry the same weight as the OE passenger rated tires. In stock size, 44psi is the correct pressure in an LT (whether C, D or E) to match the load carrying capacity of the stock, p-rated tires. Run lower pressure at your own peril.

The Explorer issue in the 90's was caused by underinflated tires, not because of a design defect in the explorer or the tires...

 

I run 35-36 psi on my E load 265’s. Ride is great and the tread contact patch is even.

 

And this is why the chalk test is trash. The tread is not super flexible so a few psi off isn't going to show up as lack of contact, especially when low because that requires the center to bow up to show lack of contact (which it is less inclined to do than it is to bow out under higher pressure) however low pressure allows more sidewall flex (which is why people want to run a lower pressure on these) but sidewall flex generates heat (see 1990's Explorers). The manufacturers association publishes a pressure guide for a reason (and I didn't think it took an engineer to figure it out but maybe it does).

 

Op, id just run 265 70 17 toyo rt trails which comes in c load.

 

Well that didn’t take long. Allen wrench stuck in the tire today.

 

It does. Tires are quite complex parts of a vehicle.

 

Yes, tire manufacturers are very clear about proper inflation: Nitto specifically states 43psi cold for it's Terra Grappler G2 LT265/70r17 (E Rated) mounted on a 4Runner. A good question to ask when considering which tire load ratings to get: What is the most hazardous road I will be driving on? Get tires that will get you home from that road.
