LT or SL? Toyo Open Country A/T III

When I began looking for tires I paid close attention to weight but also wanted a durable and aggressive looking tire, but not an MT. I knew I was going with a 285/70R18 and although I'm not sure it's the lightest LT, of those in comparison the AT3's were the lightest. I think I was comparing to DuraTracks, Falken Wildpeaks, and maybe one other? The AT3's were almost 10 pounds lighter on average. One of the nice things about the 10 ply tires as someone mentioned is that they're extremely hard to puncture.

Hi! Are you on stock suspension/no lift? I’m considering 285’s as well (but on 17’s with a + 35 offset).Trying to see if they fit without modification.

I originally installed on stock suspension w/ only the slightest rubbing in full right turn backing up, and not enough to bother trimming plastic. With the other heights I've had the aftermarket suspension set at, +1.75" up front had a decent amount of rubbing, again full right in reverse, but +2.5" up front has no rubbing at all.

What was the diameter of the wheel on your 18s?

AT3 285 on a 17 would be 33 and 275’s on a 17 would come out to like 32. Wondering if I can get away with 285s on 17’s without lifting
 
Not sure I understand your Q... The dia. of 18"s is 18"......
Whoops! My bad haha. I meant overall diameter.

This is for the 285/70/r18

Oh you're talking tire!!!! lol My fault! I believe Toyo says they're 33.7?
Got it! I think I most likely will go with 275/70/R17 E for the AT3’s. The lightest in that size I’ve found so far at 51 pounds.

Do you have photos of your nice ride?

We put Toyo ATIII E series on our LC. We have installed these tires on 4 Toyotas and been pleased with their performance. If you are concerned with rough dirt road travel, a good way to soften the ride is to air down the tires. Obviously this is a hassle if just a short distance but for long dirt roads, it works great. A compressor will allow you to air up the tires when you are out of rough country. Not always convenient but it makes a huge difference. Air compressors vary in cost and efficiency. They are available from multiple sources.
me too. My FE delivered with Toyo ATIII. Amazing Beast Offroad, 8k. Probably my next bet will BF KO3.

You would need to reposition components near the wheel well as well as a lot of body trimming, As 35s are bit aggressive looks

His offset is +20. With less poke (+35 or more) he would have no problem with 285/70/18. He could even go larger in diameter with less positive offset.
Also, you are talking 285/70/17, which is even smaller in diameter. You should have no issues- just watch the offset.
 
Im sorry, I meant to say higher positive offset. Our trucks come stock at +60 which keeps tire tucked in wheel well. The closer you stay to that offset the larger the diameter tire you can go. I am sorry if this is common knowledge.

As noted above a 275 70r 17 is a 32.2 inch diameter tire. The 70r is the ratio of the sidewall to width. The smaller the rim the bigger the sidewall and changes the overall diameter(smaller).
On the 17 inch rims you can choose a 34 10.5 r17 Toyo AT3. It is a 33.6 inch diameter tire a “34” if you will. It comes in a D rating (8ply)which is super durable but not as harsh as the E and fits much better in the spare well and weighs 54.9 lbs. a few of us run them and they need no suspension modification at all as they are a hair thinner than the 275’s. Best blend of on and offroad IMO. I would put them on my rig again in a minute.

Im set on the Nomad 504’s with +35 offset so thank you for reassuring that I will be fine lol

Correct, the TH rims are a +20mm offset. Not a fan at all of a lot of poke out, and there's only mild with these rims. Also, with the front lift set at +2.50" and aligned I have no rubbing at all.
 
I'm running the LT C range Toyo A/T IIIs and can confirm they have a compliant ride and handling, especially if tire pressures are kept close to stock. Great performance off road and in snow, as expected with deeper tread. Tire noise is somewhat elevated and there is probably a 1-2 mpg hit.
I potential alternative for those wanting to keep OEM levels of ride comfort and MPG are the A/T III EV.
I have the ATIII EV, and can confirm - hardly any noticeable difference from the stock tires. Smooth as silk.

Sorry if this isn’t a good question but again, new to this.

For the 275/70/r18, I notice that the C rated is actually heavier than the E rated. Why is this? And what would the benefit be of getting the C rated over the E rated since the E rated are lighter?
