20" tire recommendations

[feifan]

I'm running Wildpeak AT3Ws, 275/60R20. It's a D-load rating at this size (the 275/65R20 is E-load and much heavier). I usually get around 1.9–2.2 miles/kWh when driving on dry highways around 70–75mph in mid-40s to mid-50s weather.

I'm really curious about the Toyo Open Country EV tire, since it's supposed to be much more efficient than a typical AT tire. If you can wait a few weeks for it to become available, that would be worth checking out.

I've been eyeing this one too based on one of the other tire threads. My R1S is only a month or so old so I'm happy to hold off on switching for now....I just really want some better range in the future though.

I'm really considering moving on from my Pirelli AT's due to range impact. Looking forward to seeing more AS alternatives that aren't garbage in snow.

I moved from the Pirelli AS to the Michelin Defender LTX M/S2 when my Pirellis wore out. Really like the LTX M/S2. Used them in Tahoe this last week in a lot of snowy icy conditions and they worked like a champ. Really confident, solid, plowed through crud way better than my pirellis did last season.

lots of important factors, tire weight, load rating, UTQG, dimensions,

At 53 pounds (123 load) Toyo EV tire is a poor choice for any EV, the warranty is also only 50k miles. First size available is 275/60R20, seems they are chasing Ford or other non-Rivian makes…

better off with the OEM Scirpion AT+ at 48 pounds (116 load) which is snow rated…

another better option than the Toyo is Continental Terraincontact H/T 44 pounds (115 load) and snow rated….

best all around tire is prob the Michelin Defender LTX M/S2, 40 pounds (117 load), long lasting tread compound 70k miles.

only towing at the extreme range would justify the Toyo, great tire if you made a dedicated set for towing/snow…

For towing I would prob. Go for the Firestone Destination XT before the Toyo though at 51 pounds (125) in LT285/60R20 and 33.5” height.

how is your efficiency with the defender ?

@skyote 's video on the LTX Platinum just dropped

Interesting that he went with a load E tire if not going off road at all, 40# tire can achieve 2.7 mi/kw, 60#/40# = 1.5.
2.7/1.5 = 1.8 mi/kw for the heavier tires.
That’s roughly 27 mpge vs 18 mpge. Or for those with cheap electricity ~80 mpge vs 50 mpge. I would also go for the 40# tires (275/60R20 or 285/60R20). Save $1,000 per year with the lighter tires.

Sounds like Defenders come in around 1.8 mi/kw at best…

Thanks for this. Finally some information on the OEM tire size (275/65/20). My takeaway is that while there is a lot to like about the Defender LTX Platinum, increased efficiency over the stock 20" Pirelli Scorpion AT is not to be expected, without sizing down to 275/60/20 (33").

Just as a counterpoint, there are a couple of reasons why I am not doing this:

I already have a full size spare (275/65/20), so I would be out the cost of another tire to convert to the smaller size. Then there is the cost of recalibration, which anecdotally seems to vary wildly, may or may not include cameras, or may not be supported at all according to another thread. I also really like the larger sidewall with the 20" wheels - ride comfort, curb protection and it just looks "right".

I wonder how the Defender is with respect to noise after 10K miles?? My biggest complaint about my OEM Pirelli tires is how loud they've gotten once they passed about 12,500 miles.

Are you talking about the platinum?

That's what I'm looking for, a 2.7mile/kw tire that isn't $500.

Agree, the big question is do you want >350 miles of usable range, or are you ok with only <220 miles usable range…seems like a very easy decision to me…
that said, I’m sure there is a small group that’s totally happy with going 200 miles between charges…

 

[ksurfier]

That’s the tire you want then:
General Grabber HTS60 275/60R20:
34 pounds
$212/tire
