Looking for wheel size suggestion

[Puttyandnapalm]

I'm going to swap out my 20" tires when they're worn out with downsized 275/60R20 Pirelli all seasons. That'll get me to an overall diameter that's about the same as the 21" wheels.

But with my current 20" and factory tires, I'm averaging 2.5mi/kWh going 70mph 100mi a day. All purpose, standard height, high regen and stiff suspension settings.

$180 bucks from Rivian to change settings, plus potentially another $400-500 if your cameras need adjusting.
I’d stick with the 275/65/20. Plenty of all seasons in that size

It depends if you're coming from having stock 20" wheels or the stock 21" or 22". The presumption is that if the diameter stays the same then you don't need to recalibrate.

Totally a side note, but I'm waiting for someone to put some much smaller summer tires on their R1* to see how it effects the 0-60 (probably better) and 1/4 mile (probably worse) times.

Would you mind sharing a screen shot of the life-time miles showing 2.5 on the 20"?

I hear people often quote these kinds of numbers, and they are such a wild world away from my real life experience, that sometimes I wonder if it can be real...

Below is my experience with 22s since December. It was a tough winter and truck handled it like a champ. Mild off road. Stock tires are shot and will be changed for Toyos next week (quoted $1600 by a local shop). I hope it helps your decision on size and style.

General Grabber HTS60 on discount tires is selling for 950$ per set. That is the cheapest and there are a few others other than the OEM. Specs including load ratings are comparable. I have checked a few other sites and there are options below 1000$. I dont know how to check or know the rolling resistance.

Consumer Reports tests tires for rolling resistance. They rated the General Grabber HTS60 as "Excellent".

For comparison, the stock 20" tires (Pirelli Scorpion A/T Plus) are "Good", and the stock 21" tires (Pirelli Scorpion Verde A/S) are "Excellent". The stock 22" tires (Pirelli Scorpion Zero A/S) weren't rated.

Similar topic, but starting with a different wheel size:

I've got an R1S with 20's coming. I am thinking of replacing the stock tires with General Grabbers in the same size (275/65/20). So far, they are the only same-size option I've found with "Excellent" rolling resistance that also have sufficient load and speed ratings. (Michelin Defenders are really close, but just miss the speed rating at that size).

I will also look at 275/60/20 tires that are the same circumference as the stock 21's (for example, the Scorpion Verde A/S also come in that size). But then there's potential issues with tire shops not wanting to install them and Rivian reluctant to adjust the tire diameter. Some here have have been able to overcome these, but not all and I hate rolling the dice.

Good piece of information on the settings!

I have the 21". They're great for efficiency, but I think the 20" wheel size is the way to go, based on:

• 20s are much easier to find A/T options if you want them.
• 20s are cheaper to replace, so you'll save $ in the long run.
• 20s have quite a few A/S options out there that are nearly as efficient as the 21s.
• The deal-breaker for me, is that if you damage a tire, you can get new 20s pretty much anywhere you are and get back on the road. If you have 21s, you're possibly looking at a multi-day delay while trying to track down an OEM replacement.
• I personally think the 20s look better.

The only thing I worry about is the fact that some folks are mentioning that the load/speed rating is different and low for the non-OEM 20s. Haven’t done enough research on this though.

There are plenty of options with a load and speed rating that will work. What I don’t understand is what makes a tire EV specific other than the sound dampening part…

Based on positive experience with majority of responders, I changed my configuration to 22" wheels at the risk of losing my spot in the line. Learnt a good deal from all of you. Thanks.

After I did so, I saw the response from Fencer. Can you please clarify. Did you get 25k miles with the stock 22" tires? Is 2.16mi/kWh your average for the last 25K miles. Isn't your estimated range on full charge well short of 303 miles for 22" wheels.

Below is my experience with 22s since December. It was a tough winter and truck handled it like a champ. Mild off road. Stock tires are shot and will be changed for Toyos next week (quoted $1600 by a local shop). I hope it helps your decision on size and style.

Thanks very much for checking. Glad to know that < $1000 tires are excellent replacement tires.

Driving on 22’s on my loaner truck and I haaaate it. I can feel everything on the road and I am nervous about pot holes plus they’re so ugly. 20’s are really great and 21’s are amazing they feel like you’re gliding.

I went with 20" just because of the wide range of readily available replacement options. Both in stock 275/65R20 and -1 275/60R20 sizes.

That's fine with me to have them do it once. I drive at least 40k miles a year so the difference in tire cost and electricity over time will pay itself off

Totally agree.
