Tire Replacement Info

[Strobe]

Just in case anyone else would find this useful...

My vehicle: Gen 1 quad R1S, large battery
I'm at 34,500 miles on my OEM 20" Pirelli Scorpions. When my snow tires go on this winter (Nokian Hakkapeliittas), I'll be replacing my non-winter tires. I had no less than five tire threads bookmarked on this forum and have read over 300 posts about replacements. With information overload, I decided to summarize the parameters that are important to me (of course, there will be other opinions and priorities in the forum). We do mostly highway travel and trips to national and state parks that require light or zero off-roading, and trips to Colorado ski areas. I want low noise, good efficiency, good wear, and good to excellent rain/snow performance. Even though I have dedicated snow tires, I have been surprised more than once by a late-May heavy Colorado snow after removing snow tires. I don't care at all about the looks of the tire. Two winters ago, as I was sliding sideways in 23 inches of snow toward a ditch, I never once thought, "well at least my Pirellis look awesome." (epilogue: my brand new traction boards at the time worked great!). I also don't care about price. With 7500 lbs of car under me driving through the Colorado mountains in all weather, and after a couple white knuckle moments, I want the tires that are going to keep my family safe.

The tires below have all been discussed in forum threads. What struck me was that for every one of these, for every person that said "I love these: improved efficiency and greatly reduced noise," another person would claim "I'll never buy these again: reduced efficiency, and louder than my Pirellis." So that is why you don't see a column on "Forum Reviews." But I did get some good info from the personal experiences of others and greatly appreciate all those that provided comments.

The prices all come from TireRack.com. All the tires are 275/65R20 except the Goodyear Wrangler ATs that are 275/60R20 (and not available in the 65s). The reviews come from TireRack, but some of these tires are too new to have published reviews.
For me, and for what it's worth, I am leaning toward the Toyo Open Country- SL. I like that it is designed for EVs, has low rolling resistance and a 3 Peak Mountain Snowflake rating, and still provides an off-road capability. It's still a close decision between the Toyos and the Michelin LTX M/S2s. Over many years of driving, I've had great luck with Michelins, but I'm leaning toward the Toyos.

I have a '24 R1T large and for my summer tires have chosen the Toyo Open Country H/T II in 275/60/20 LT config. These come with a load rating of 123 (3415lb). They also come in 275/65/20 LT. I don't offroad but do travel on gravel roads at times. I don't care about appearance - I look good enough driving past gas stations without stopping. I do tow big loads at times with a heavy tongue weight. My criteria in order were:
1) optimal efficiency
2) quiet
3) can tolerate towing heavy (10,000lb)

The H/T II meet that bill nicely. Well mannered on the highway, quiet, and I don't have to worry when I hitch up my trailer to get wood.

I haven't seen anyone mention this tire on the forums and am curious why.

No reason other than matching the specs of my original tires. However, I am aware that Rivian is delivering new vehicles with 33" Goodyears, so I probably should be looking at more 275/60R20 options. Thanks for pointing this out.

Per @usulio 's recommendation, I updated the chart with 33" (275/60R20) options where they were available. These options showed a 1 to 6 lb reduction in weight. But combined with the smaller diameter, there should be some improvement in efficiency. So now I have more options to mull over.

Went from pirelli AT 275/65 to defender all season 275/60/20 and saw a very negligible increase. On my commute I gained about 3 kWh better

That's a good data point. Thank you.

That's a good data point. Thank you.

I’ll continue to compare some things. I started a log shortly before I swapped the tires. But honestly with the ride quality and noise improvements, I’d give up efficiency with these Michelins lol

I wanted to close the loop on this thread.
Until the last minute, I was on the fence between the Toyo Open Country AT III EV (SL), and the Michelin Defender LTX M/S2. I liked the 3PMSF rating of the Toyos, but the potential efficiency gain on the Michelins.
Ultimately, rational analysis won out. We do a lot of camping, but no moderate or extreme off-roading. I already have dedicated rims and snow tires. And, we do a lot of cross-country driving.
So when the snow tires went on this year, I swapped my 20" OEM Pirellis, with 38,000 miles, for the Michelin Defender LTX, and went with the 33" diameter (275/60R20).
I just need to go into settings when they're mounted next year, and change the tire size. (Of course, I'll forget to do this and marvel at my efficiency gain!)
I won't have any feedback on the Michelins until next May when the snow tires come off.
I really appreciate all the suggestions and feedback from the community on this forum.

You won’t regret the traction and ride of the Michelins.

I've had a great experience with Michelins over a number of cars and multiple decades.
I think you are correct!

I ran into the same issue and ended up going with a shop that handles heavy truck tire repair Montreal style—big equipment, solid gear, no fuss. They were quick and knew their stuff working with larger electric trucks. If you're in the area, it's worth checking out since they didn’t flinch at the R1T’s weight and had the right tools to get it done safely.
