Toyo Open Country AT3 - P vs LT?

[Popplemer]

Thank you for this.

I ended up ordering the Falken Wildpeak AT4W’s today, in 285/65/20… it is an E rated tire.
Probably overkill for only having snow 3-4 months a year at our cabin, but the snow/ice reviews I’ve read have all been exceptionally positive.

I nealry died last year rolling off a cliff, in the mountains, in snow conditions, due to inadequate tires on a rental SUV. After that, I’d rather be prepared than risk it on these sketchy nittos. ?

Jeez that's terrifying. Glad you made it! I cant fault your logic for sure. I know everybody is different but the ride quality is more important on my end of things. I'll also say I have Wildpeaks on my F-250 and with the added weight of that truck I absolutely love the ride. I hope the Falkens treat you well!

We run their P rated tire on our Gladiator EcoD. It has 50k miles almost exclusively over-landing with heavy trail use. We've never had so much as a minor puncture. I was worried enough to get a full-sized spare and haven't needed it since. In rocky areas I'd air down to 20psi and still no issues. They are a fantastic tire. That said we'd avoid pure rock crawling so if that's something you're into for sure get something with a 10-ply or better sidewall.

Might I ask what tire you're running? As stated I'm a p rated fan

Facts, but I think it depends on where you live and if you're able to just stay at home for a day or two when it snows heavily enough.

It seems to get warmer and warmer with less and less snow with each passing year in the MD/PA area. We would typically have winter tires on all cars but we may go in the direction of just having one AWD/4WD vehicle with winter tires instead of all our cars.

When I lived in a much flatter part of the country, I had no issue running all-season tires year round despite heavy snowfall and I was able to get around just fine even during snow emergencies when all emergency services were suspended due to road conditions.

When I moved to an area where steep grades were common, it became clear that this wasn't a good option anymore. Last winter there was decent size crash on the long winding 10° hill at the end on my street. With my Blizzak DM-V2 snow tires, I was able to confidently drive down the hill and weave between the disabled cars without any real concerns about losing traction and sliding into them.

When I ran Falken Wildpeak A/T3W tires on my 2014 F150, driving down the same hill in the winter was dangerous as I had to choose between braking to maintain a safe speed and steering to avoid running off the road. If I tried to lightly drag the brakes and turn the steering wheel at the same time, my truck would start sliding almost immediately.

The Falken tires were basically brand new at the time, but they weren't ideal for the steep roads I drive on. Climbing up the same hill they were fantastic and they did exactly what the 3PMSF rating claimed they would. Coming down the hill was an accident waiting to happen as I had very little control over my vehicle. On flat roads I would feel comfortable going with the Falkens again, but I won't run them where I live now. The Falkens are one of the best rated all-terrains with a 3PMSF rating, but they just don't compare to Blizzaks.

Nitto also rolls with a SL rated 305/55/20 (33.2") Ridge Grappler. I actually plan to get this tire for my 2024 KR Powerboost. It is aggressive with a 12.5" wide tire and only weighs 52 lbs.

Better off with the 275.65.20. 34" tire fills the wheel wells better and you won't have to deal with the range reduction the 305 brings. 33" tires, especially on a leveled truck just look entirely too small. I have one of the lightest LT275.65.20s and saw no mileage hit doing the same exact course back to back vs factory 33s. The only thing a 305 does in comparison to a 275 is decrease in mileage and increased risk of hydroplaning.

What tires are you running at 275/65/20?

Revo 3s. They were already on a set of wheels I bought and haven't found a need to change them. Not really an endorsement of the tires. The wheels/tires were cheaper than the wheels I was going to buy so just left it as is. I was going for 275/65s in the first place and it was a super good deal so I truly lucked out.

I thoroughly enjoyed that thread. Thanks for taking the time/effort to do that because it dispels some of the myths about moving to LT tires of similar (not identical size). It confirms that a change in compound and tread design may matter more than simply load rating (weight of tire).

I hadn’t thought about differences in tire compound affecting mileage so much but that makes sense. Comparethetire.com says Toyo AT3 has a harder compound than Yoko G015 leading to better mpg.

I know weight has a notable effect and rolling resistance from aggressive tread pattern has some effect. When I switched to 295/60/20 Nittos I lost 3+ mpg with the biggest drop coming on short trips. I‘d guess that is the cost of getting heavier tires rolling. On the highway I can get 22-23 if I keep it under 70.

There's a bit of a misconception regarding tread width and grip. Tires have really become niche to vehicles. The Mach-e for instance on its 245s weighing in at 5klbs can pull more Gs on the skid pad than a 3klb C5 vette with 245s front and 275s rear. Compound hardness and widths really need to be matched to a vehicle. Going with a 295 kills mileage and gains nothing. The piggyboost coming in at 6klbs is plenty of mass to shove a firmer rubber at 275mm into the pavement to retain grip. There's really not a one size fits most any longer. Take into account compound / mass / size etc for best performance.

I got the 295s because I wanted a beefier look and found a killer deal. I wanted 285s but the deal was too good to pass up. Now i’m thinking 295 is beefier than I prefer and would rather regain some mpg with 275 or SL rated 285s.

IMO the recon grappler in SL 275/65/20 is the clear winner if you live in the south. There’s just not a lot of similar options. It would be the first thing I’d do if I moved.

Up north there’s really nothing available atm that is similar with softer compound and preferably three peak

Agreed.

Even from a performance perspective, your track oriented cars already have what I would consider optimum sizing of tires straight from the factory - ie. C8 Z51, S660 DH + Handling Package, BMW M cars, etc. The only changes you're really making are:

1. Compound - stickier compound
2. Sizing - but I think most of the time this is done to try to get to a square setup if possible to enable tire rotations for better wear and lower cost without being a detriment to performance

Compound will matter more for dry traction than tire sizing.

I live in Atlantic Canada so needed a better winter tire than stock hancooks, I could barely get out of my subdivision with them. I decided to put on SL 275/60R20 Toyo at3 to save some weight and help with maintaining power boost MPG. As 90% of my driving was highway or city and I don’t do much towing and when I do it’s just a boat or utility trailers.
I was worried about punctures when off roading on logging roads with sharp to get to hunting and but after 2 years I’ve had no issues and continue to push through deep snow and fields when hunting and fishing.

I have put about 40,000km on them and they have worn down to 9/32. And I can tell they aren’t as grippy as when I first got them and will likely run them the rest of this winter and summer and get new tires next fall.

I previously had Goodyear duratracs on my ‘19 f150 and the snow/wet grip is not as good as those but I couldn’t stand the noise that developed after 15000-20000km on the duratracs. So far the toyos have worn very evenly and are still as quiet as the stock tires rotating them every oil change.

picture was taken 40km back unplowed logging roads the day after a storm and we were first tracks in. Was 2H the whole way no need for 4wd.
