Any regrets running load range E tires?

Does anyone regret putting load range E tires on their Gladiator? What are your biggest complaints?

It might be my imagination but it seems like it is harder to get them rolling from a start. It could be the change in the gear ratio as well, though.

They’re considerably heavier so you’re increasing your rotating mass and unsprung weight. So of course you’ll feel a difference. Part of the reason why I’m doing a 265/70/18 on my Overland (only want to go to 33s) is because other similar tire sizes are only available in E load. I already took a big hit in mpg when I went to my Gladiator from
My 2017 3.6l/8 speed auto All Terrain Canyon so I’m trying not to make it worse.

Heavier tires equal more rubber which in a quality tire equals toughness and durability. Hight end brand E rated tires will ride and drive better then low end D or C rated tires. The idea that E rated equals a bad ride is an outdated thing.

You can’t dispute the increasing rotating mass and increased unsprung weight though. It’s going to make a notable difference. Are E Load bad? No. Not at all. Actually, they’re good to have if you are going to do a lot of off-roading where the stronger sidewalls will help avoid sidewall punctures. I can’t see myself towing anything in my JT that a quality non LT all terrain can’t handle though. That’s my uses. I’m just answering the question.

Not all tires are created equal is what I am getting at. OP, look at all the tires that you like and get the specs on them, weight and tread depth and actual diameter. For example look through the thread about 37's in this forum, you will see that there are up to 15lb differences in weight for tires of the 'same size'.

Which E rated tires are you looking at? Why? Aren't they available in D rating?


Our friends @Discount Tire provides this starting point:

There's also a load rating index that's relevant - here's that info plus the above chart:

https://www.discounttire.com/learn/load-range-load-index

The load range is identified by a letter of the alphabet, usually from A to F, which represents the ply rating and load pressure.

Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.

And the weight of the tire. Then compare them and see how much of a weight difference you're looking at. And then ask yourself how important that weight difference is.

And compare sidewall ply (plies) and ask yourself how much that will matter to you (if it will).

Don't forget to consider how much weight you'll be putting in your truck and if/how much you'll be towing.

Here's a post from an off road forum that's relevant...

"...most 10 ply tires have a harder rubber compound and will last longer than a 6 ply tire. Do you need them? probably not, will they last longer? A good 6 ply will last as long as a cheap 10ply. The 10 ply will ride a little ruffer and will probably net you a little in fuel economy and still probably not enough to matter but, add up the pluses and they will pay for themselves in time."

I'm running Toyo Open Country R/T tires - they're D rated and they're great.

37x12.50-17

Great traction, super "quiet" on the pavement especially compared to most M/T tires and other R/T tires. Extremely durable 8-ply side walls which are great for off roading. Plenty of weight/towing capacity (more than needed). The 78 lb. weight has not been any issue at all but I did re-gear (4.88 front and rear).

Here's a great thread on the JL Wrangler forum posted by aCeMedic13 - it's worth looking at as it lists lots of tires, sizes and weights https://www.jlwranglerforums.com/forum/threads/popular-jeep-tires-size-weights-specs-pics.8603/

Working list... Feel free to add.

Rating (C,D,E) Ply - Thickness of sidewall. Additional protection + load = stiffer ride.
Actual diameters are listed - Width should also be taken into consideration dependent on wheel/rim of choice.

A three-peak mountain snowflake (3PMSF) symbol branded on a tire's sidewall indicates the tire meets required performance criteria in snow testing to be considered severe snow service-rated. 3PMSF-branded all-season and all-terrain tires cannot match the traction of dedicated winter / snow tires in all winter weather conditions and should not be considered a replacement for where and when a dedicated winter tire is needed.

Listed Tire pressures are manufacturer recommendations (See post #25 for explanation).

I wish they made more C loads. Especially, for my 18” wheels and 33” A/Ts.

I would just get over the C vs other loads and get the tires that make you happy when you look at them. How light do you want your tires to be? I high end AT tire is going to ride great even with an E load rating, tire pressures need to be adjusted according to preference.

My Falken AT3W's are E-rated and drive fantastic, very smooth. As for fuel impact I have no idea as they were put on before I picked it up from the dealer.

 

[WhatExit?]

FYI: Jeep selected Falken’s WILDPEAK A/T AT3W tires for the Gladiator. Size is LT285/70R17 (116/113Q-rating) as standard fitment, while also available will be the LT285/70R17 (116/113Q) WILDPEAK M/T (Mud Terrain).

The Falken tire has a 116 load index = 2,756 lbs.


More info - load range, ply rating and max load (at pressure)...

Right, but you can’t tell me that going from a 32“ P rated all season all the way to a 33” all terrain E load on my stock 3.73s isn’t going to make a bigger difference in my mpg than a P rated or C rated all terrain. I’ve been paying attention the weight differences and it’s huge.

I know my case is different than most, I took a HUGE MPG hit going from 2017 Canyon All Terrain (3.6l/8 speed 4wd). I got 24 mpg hwy consistently to 16-17 hwy consistently. I need to take it in and see what’s up, but I definitely can’t make it worse so I’m actually going to probably keep it at a P rated all terrain going from the stock all season 255/70/18 to a 265/70/18 A/T. I’d do a C Load if anyone knows a decent A/T C load in that size.
