Just installed the recently launched Pirelli Scorpion XTM All-Terrain Tire with gas and EV variants. 34" Tires on 20" wheels.

I just got the new Pirelli XTM AT tires installed on all 4 corners with road force balancing on my Rivian R1S with 20" wheels to clear the OEM calipers.

Car and Driver Review of Pirelli XTM AT

The new Pirelli XTM AT is a 34" All terrain tire with Three-Peak Mountain Snowflake (3PMSF) requirements (275 /65 R20 116T SL BS) and 55,000 mile tread warranty.

It’s supposed to be better off-road and better Sidewalls for improved puncture protection along with better mud traction + snow/slush compared to OEM Pirelli Scorpion AT+ tires made for Rivian with 50,000 mile tread warranty and 3PMSF rating.

You can see the “Elect” marking - for electric vehicle on the new Pirelli XTM AT tires I recently installed. The ELECT™ marking on the sidewall identifies Pirelli tires, specifically developed for high performance electric and plug-in vehicles, in line with the Perfect Fit strategy.

I feel like the only compromise is grip is good but not great when compared to OEM Pirelli Scorpion AT+ made specifically for Rivian to perform really well. They did a great job being able to hold grip on twisty roads while using up all 800 + HP / 900 TQ.

Next up is alignment with Rivian tomorrow.

I’ll post my full review once I get it back from Rivian and put some miles on it.

For now what I noticed is the steering is very responsive and grip is good.

I still need to test some more after alignment because that my impression with 4 miles.

I got like 1.92 miles per kWh in those 4 aggressive miles which is in line with what I expect.

Normally I average 2.00 miles per kWh with road trips in the mix with my lead foot on 34” AT.

After driving 60 miles on my way to drop the vehicle off for alignment / service my impression is it’s very cushy / comfortable tire for on road and does a solid job soaking up potholes, dips and manhole covers compared to OEM Pirelli Scorpion AT specifically made for Rivian. The OEM tires did a great jobs with holding grip and taking 800+ HP / 900 TQ with no problem but got loud roaring noise around 15,000 miles, snow performance was not the best and off road performance was good but not great and / mud performance was okay.

For me to get the excellent on-road grip I am looking for that can handle back roads / twisty roads or launches will be to get a set of 22" Sport wheel with Pirelli Scorpion Zero All Season tires made specifically for Rivian with grip / handling in mind (HL275 /50 R22 116H XL BSW RI).

I got 27,700 miles from OEM Pirelli Scorpion AT+ 20" tires with fronts at 2/32 and rear at 3/32. I cross rotated the tires twice in that time. I went off-roading and used all 800+ HP / 900+ TQ daily on road. I liked the overall grip / performance from the OEM tire but did not enjoy the noise after 15k. The Rivian OEM Pirelli Scorpion AT+ tires typically come with 50,000 mile tread warranty 640 A B for treadwear / traction / temp.

The New Pirelli XTM comes with 55,000 miles tread warranty and 660 A B for treadwear / traction / temp. The XTM AT is a lot quieter / comfortable ride even when compared to a new set of OEM Pirelli.

Feel free to check Discount Tire if they have the new Pirelli XTM AT tires for your lightning already available for your wheel size or possibly later once they release all tire sizes.

I paid full price out of my own pocket and did not even get a discount for buying 4 tires or any sort of mail in rebate ($80 - $100 prepaid card when you buy 4 of a certain brand during sales)

https://www.discounttire.com/promotions

I was not compensated a single penny for it.

Every dime came out of my pocket for the tires / alignment and mounting / balancing.

You can try the tires for 60 days under the Pirelli guarantee and if you don't like it you can exchange it for another tire made by Pirelli.

That is what I plan to do. Try these and see if I am happy with them or I want to go back to OEM Rivian Pirelli Scorpion AT+

I would be happy to take a donation towards my tire fund that is running low thanks to my lead foot

You can see the below receipts from Discount Tire and delivery information.

Why are you a diamond sponsor then? There’s gotta be some upside.

Why are you a diamond sponsor then? There’s gotta be some upside.

No upside at all for any sort of tires.

I am a diamond sponsor so I can post affiliate links for A2Z EV / Lectron charging adapters / products.

Now you do bring up a good point about upside and I might have to check what sort of affiliate options Discount Tire, Simple Tire or Tire Rack have.

Feel free to go anywhere to buy your tires and buy any brand you want.

I just wanted to share my experience on a recently launched tire (April 8th, 2025) that has very little real life reviews on it.

Thanks for the review!

And some of us recognize you can be a sponsor AND an a contributing member.

 

[Nolander]

Interested to hear your findings on range impact.

Thanks for the review. Looking forward to your results of the 60 day trial. Pirelli, although pricey, was my goto motorcycle tire when I was an avid motorcycle racer. The reinforced sidewalls is of interest as our NM mountain roads are brutal on tires. What kind of tire pressures are you running? Are you doing any towing?

 

[F150ROD]

So did you choose the Elect variant which is what is kind of relevant here, we already know what regular AT tires do to our range...... what difference in Range have your noticed?

It would be an interesting comparison with the Toyo Elects

Yes, I got the ELECT version.

No towing at this time but at some point during the life of the tire I would like to tow a small airstream. I can report back my experience but I am sure someone will end up towing with these tires before I get to it.
