We’re on track to get 50-60k+ miles out of our tires!
Here are all the details:
We took delivery of our R1S (Gen 1, Quad, Large) on Sept. 30, 2023 and made a beeline directly to Discount Tire to take off the 21” road wheels and put on a set of (5) of the EV Sportline R800 with the Falken Wildpeak A/T3W in the OE size of 275/65R20. Why the Falken Wildpeaks? This discussion thread is exhaustive, but extremely informative, and solidified my decision for these tires. 11 months later, and I don’t regret it!!
“Why 5 All-Terrain tires?” you ask? First, they look SICK!! Also, I do some REAL off-roading every few months, so AT tires and a full-size spare were a must. I live in Boise, ID and we get a fair bit of snow here, so the 3 Peak Mountain Snowflake rating is a good idea. The OEM Pirellis have thin sidewalls compared to all other AT tires on the market (see the weight differences below) and they start at 14/32” tread depth. The biggest reason for choosing the Wildpeaks over BFG KO2 or Toyo Open Country was the starting tread depth of 18/32” vs. 15/32” for the KO2 (and others). That added tread depth means a massive difference in usable life!
“How often are you rotating?” you ask? We are doing a 5-tire rotation every 5,000 miles. I just hit 20,000 miles, threw the spare in the back, and ran over to Discount Tire for the 5-tire rotation. This rotation means all 4 of the tires on the vehicle now have the same 15k miles and the current spare has all 20k miles on it. All of the tires currently measure at about 14/32” tread depth. That means about 1/32” per 5,000 miles. Assuming replacement between 8/32”-5/32” remaining, that means anywhere from 50k-65k miles. If I wanted to go down to the wear bars at 2/32”, I might get 80k!
“Do you drive like a grandma?” you ask? ABSOLUTELY NOT! I drive it like I stole it. Anytime a Rivian newbie gets a ride, I have to show them a launch! I have 908 lb-ft of instant torque beneath my right foot, and I like to use it.
“What drive settings do you use?” For around-town driving, we like the look of the high ride-height and we have the MegaWatt Rockslider/Step, so kneel mode isn’t needed. We drive around for our daily stuff in Off-Road Rally Mode, High ride height, soft, max regen. We’ve taken road trips from Boise to Anaheim & back, Seattle & back, and Hillsboro TX & back (for the eclipse). For those long road trips, we use conserve mode in standard/low ride height. The tread wear has been very even on all 4 tires.
“But what about efficiency?” you ask? The R800 wheels are about 6 lbs lighter than the OEM 20” AT wheels from Rivian. The Falken Wildpeaks are about 17 lbs heavier than the OEM 20” AT Pirellis. At a net increase of about 11 lbs per corner, I knew I was going to take a big hit on efficiency. But since I’ve never even driven around on the OEM tires, I have nothing to compare it to except the efficiency I’m seeing others achieve. I also run at about 63 psi to try to reduce the contact patch a little bit. During the first 5-6 months of ownership when it was cold here, we generally saw about 1.75 mi/kWh. Once it started warming up, we started to see about 1.95 mi/kWh. Over the 20,000 miles total and almost 4 full seasons, we’ve averaged 1.87 mi/kWh. Electricity in Idaho is CHEAP (about $0.10 - $0.12 per kWh), so the efficiency losses aren’t really a big cost factor for daily life. The efficiency has really only been a problem on I-80 in Wyoming where the 212 miles between Evanston & Rawlins charging stops meant I had to charge to 97% at the EA stations and get creative by drafting close behind a semi for 100 miles of the stretch.
“What about performance and ride quality?” you ask? Again, I don’t have any experience with the OEM tires aside from demo drives and service loaners. The Wildpeaks seem to be comparable on-road in terms of noise and responsiveness. Off-Road, the Wildpeaks are light-years ahead of the OEM Pirellis! One downside seems to be balance. One of the Wildpeaks has a hard time getting balanced. I have had to run back to Discount Tire after a rotation & rebalance, and have them do the balancing again. Even after they give it a second shot, I still have a slight shimmy when that tire is on the front axle. Once it gets rotated to the rear or as a spare, no problem!
When it comes time to replace these tires, I don’t know if there’s a good reason for me to try anything else!
