Toyo Open Country III a/t evs on 22s

[plowboy7250]

Hi, guys! I’m new here making my first post and love this forum so far. It’s been extremely helpful both when making a Rivian purchase as well as for daily news and usage tips.

I got my R1T dual max in late November and ordered it with the range wheels/tires which of course come with the 275/50r22 Pirelli Scorpion MS tires. I’ve been thrilled with the truck in general but not so much the tires. Even for MS tires I find them lacking for traction on anything but asphalt, they’re incredible mousy looking, and they’re thin and seem to puncture more easily than I’d like. I’m a farmer and while I’m not using my Rivian for a work truck it still has to go off-pavement fairly frequently.

I had looked at BFG KO3 tires but they look very heavy and inefficient, and I’ve heard bad things about the Pirelli ATs that are a factory option, so I got myself a set of Toyo Open Country III a/t ev tires installed. I was worried that I’d see a big dip in efficiency going to the A/Ts, but my efficiency actually went up from 2.11 to 2.25 m/kwh in my first 100 miles. I think that’s probably misleading as much of my mileage on the Pirellis was in very cold weather on high-speed long-range trips and it’s been 50+ degrees since I got the new sneakers so that probably explains why it went up instead of down, but nevertheless it’s good to know that I won’t be taking a huge hit. These tires are only 43 pounds each instead of the BFGs which would have been 60-some I believe so that helps, though they’re also heavy enough ply that I shouldn’t have to worry as much about punctures. The off road traction has been great so far, the handling is perhaps not as great on-road as the MS tires of course but still excellent, and I really like how much better the truck looks with these Toyos. My only complaint has been the road noise, as these Toyos were advertised as quiet and they’re not that. If you have your radio below sound level 12 you will hear these tires, and they’re worst right at 60mph, though thankfully at higher speeds it seems to decrease. I’m running them at the recommended 51psi but am considering bumping it up to 55 to see if it improves, since even at 51 the sidewalls seem to squat significantly. The noise isn’t awful though and it certainly doesn’t make me regret the purchase. Honestly in a vehicle with an ICE you probably wouldn’t hear the tires over the engine.

It’s really only been about two weeks, but I have taken a long trip from PA to Raleigh and back in that time. The efficiency seems to have settled in at around 2.14 m/kwh which isn’t as good as I’d have hoped but it still seems better than a lot of AT tires, especially given that there was a lot of time at high speed on that trip. Toyo says these tires are the same revs/mile as the factory tires so I didn’t recalibrate the speedometer but they sure look bigger to me, which may mean I’m covering more miles than I think and that my efficiency is actually slightly better as well. I will say that during the trip some idiot ahead of me hauling an oversized load of garden sheds didn’t fit under an underpass and sprayed a bunch of roofing material onto the road. I found two nails in my Toyos that did not penetrate the casing and had I been on the Pirelli M/S tires I probably would have been stuck along the road with two flats.
In hindsight I wish I had run the MS tires in warmer weather a little to see just what sort of efficiency I’d have gotten with them in normal temperatures. I’ve gotten used to the tire road noise and barely notice it now. I’d definitely recommend.
