Tire question about 285/75-16

[Singtoe]

I need some input from experienced users. I want to upsize my tires and I went to a tire shop to get some pricing. I want to use 285/75-16. The Tire shop said he would sell them to me but would not recommended it. He went into the reasoning behind it because the tires are only available in load range D (8 ply) and or E (10 ply). He said the higher ply tire need more air (65+ PSI) in them to have then wear evenly. It would ride kind rough riding. He said, if I were to get them and run them at 30 psi, i would see bad cupping and poor tire life.

This is for those people who are using 285/75-16 tires.

What brand and model are you running?
What pressures are you running?
How are the tires wearing?
Will you get the 50k+ miles out of them?
How is the ride quality verses the old 4 or 6 ply tires?

I will tell you about my 265/75/16 BFgoodrich All Terrains load range E. This is the exact tire they use on the new FJ Cruiser Trail Team edition. The tire pressure in the door jam said 35 psi on those models. I keep mine a little under 40. Ride is a little stiffer, but not bad. Tire wear is good and I heard I should expect over 70k miles.

I am running load range D Nitto Terra Grapplers. I have already put 40k miles on them and run 38-40 psi on the street and 12-14 off road. I have needed an alignment for a long time and have a little feathering/ cupping on the inside of the front tires. Ride is just fine and no funny wear other then mentioned due to alignment. Rear tires are still showing good very even wear. I should be able to get another 10 out of hte fronts and 15 out of hte rear.

I only rotated twice since I never got off my backside to get the alignment done. With all the hard off-roading I do and the lack of rotation/ alignment I think that they have been good and that running the pressures in the 35-40 range you would be fine. Definitely recommend "D" range over the "E" though. remember our trucks are 4k without any heavy mods.

What brand and model are you running?
28/75/16 Goodyear Wrangler Duratrac's Load Rage E
What pressures are you running?
70 PSI- that's what the shop set it at I believe and said I'd get even thread wear that way. Some guys on here are probably going to say I'm crazy but just going by their recommendations.
How are the tires wearing?
I have only had them for about 1,000 miles but seem to be wearing fine. Can't really tell cause it's too early but there are many threads on these tires so check it out. I have got a lot of guys to buy these tires recently due to sales prices and everyone loves them.
Will you get the 50k+ miles out of them?
I'm not sure if I'll get 50,000 out of them but maybe? We'll see
How is the ride quality verses the old 4 or 6 ply tires?
The old 4 ply rode completely different than the new ones but then again I did lift and tires at the same time so that probably changed ride comfort as well. It is a stiffer ride but in my opinion it really isn't that bad. Rides like a truck but that doesn't bother me... I also have OME 891 Heavy Duty coils in the rear so my ride is harsher. I personally love the tires because they are meaty, aggressive, look bada**, and they ride better than my old ones.

^you're crazy.


But seriously. You only need 70 psi in those if you are using them on an M1 Abrams tank. You'll actually wear them out faster at 70 psi than at 30psi. Your 4runner isn't NEAR heavy enough to make 70psi correct.

Air them down to 35-40. Then do a chalk test on the tires. Or leave them at 70, do a test, then air them down and test it again. (google it)

Sorry OP, forgot about the question at hand.

On my 1996, I ran:

-BFG A/T KO
-35psi
-Wear perfect
-Easily
-Just fine. Slightly stiffer, but hardly noticeable.



Your tire shop dude is feeding you quasi-misinformation. Load range D is perfect for a 4Runner. E's are too stiff technically, but they work just fine. The higher ply tires only need more psi in them to wear evenly if they are on a heavy vehicle. As long as the contact patch is correct, any tire will wear correctly. And you can get the correct contact patch by using the correct psi for the weight of your vehicle. Chalk test! (google it)

Thanks for the info, now just waiting for my old shoes to wear down.

how many inches is the lift?

How many inches is the lift you used?

Ive never in my life had a tire shop tell me this. Higher load tires are for towing so you "can raise tire pressure" when you are loaded. You are never recommended to run full psi in tires unless its needed.

I have ran higher load tires for over 15 years and never had an issue. I have had better tire wear on higher load mud tires with lower pressure because the side walls where so stiff. Needed lower tire pressure to get a good chalk test and even tire contact.

My 10 ply experiences

I run Cooper Discoverer AT3 265/70/16 E tires on my 99 Limited. Pressure set at 40psi all around. I carry about 200lbs recover "uh oh" gear in the back all winter. My experience is positive, only drawbacks are the heavier overall weight, which I notice with braking and the ride is a bit harsher than the P-rated stock tires. But I've also gone from Michelin LTX M/S to the AT Coopers. Pillow slippers vs work boots. I've run two years in them. No troubles. Just had them Road Force balanced and no trouble what so ever.

The weight of our 4Runners will not cause the E tires to deform/flatten enough to get an even contact patch from tread edge to edge at 70psi.

Imagine a soccer ball at max inflation vs 1/2 inflation. Now you kick the max inflated ball at full force. Compare by kicking the 1/2 inflated ball at full force. Then do it all again with a 1/2 of max strength kick. See the difference in the deformation of the ball with different kicks and different pressures? Now apply this to our tires.

Yes, a 1 ton truck will flatten the tires at 40psi, but a 1/4 ton SUV will flatten them proportionally less, thus requiring less tire pressure to get the optimal contact patch on the ground (and therefore ideal tire wear and handling).

If all things were equal, I'd go with an 8ply D rated tire. Slight difference in weight and ride quality, but I'm splitting hairs.

I have the e-load duratracs in 285/75/16 and have run anywhere from 32-35 psi for road use. Wear has been great, I found running higher than 35 would make the truck a little too loose in the wet/snow (especially when low on gas).

 

[gclark14]

I run nitto trail grapplers in 285/75/16 at about 35psi. Tires have about 25k or so on them and I expect another 20k (hopefully)

285/70R17 Hankook Dynapro MT's - LR D - 34psi - 20psi offroad.

-BFG A/T KO
-35psi
-Wear perfect
-Easily
-Just fine. Slightly stiffer, but hardly noticeable.

I don't know if I ever mentioned the final disposition of these specific tires. I replaced them at just over 75k miles, and they had about 2/32" of the tread left.

Got a good deal on the new GY Wrangler Duratrac 285/75/16 load range E, so went ahead and replaced them. Also running the Duratracs at 36 psi. Should get another 70k+ miles out of this set.

What brand and model are you running?
285.75.16 Treadwright Guard Dog, Load Range D

What pressures are you running?
40 psi on the road, 12-15 psi off road.

How are the tires wearing?
Theres a little bit more wear on the outer edges of them, even with regular tire rotations and alignment check.

Will you get the 50k+ miles out of them?
I had the same tire in a 265/75/16 previous to these and I put 36k miles on them before selling them at about 30% tread on my stock wheels for $250. I have 15k miles on my current set and they have tons of tread left, besides all the wheeling damage.

How is the ride quality verses the old 4 or 6 ply tires?
They're D rated and ride fine. I briefly ran a set of E rated BFG all terrains and the ride was substantially rougher. I don't know if it was the load rating, differences between brands, or the age of the tires, but the difference was substantial. Who would have thought a cheap retread would ever ride better than one of the most popular name brand tires.
