1,000 mile efficiency report on Nitto Terra Grappler G3

[PowerBugs]

If you ever wondered which AT tire should not be on your list if considering efficiency, then the Nitto Terra Grappler G3 should NOT be an option. My lifetime efficiency on my large quad R1T on 21’s was at 2.5 and wanted to have AT tires for our February trip to Yosemite so I end up switching to @Atomic Wheels AW09 20”.
Reset my tripmeter B to reflect my new wheels and tires and initially getting 2.2 but after over 4 miles it went down to 1.9 mi/kwh. I just got 1,000 miles with mostly mixed city and Hwy driving with only one long trip to Yosemite from the Bay Area and currently sitting at 1.7 mi/kWh
I have no complains the way it handles the road wet or dry but haven’t tried it on snow yet. There is some noise as you expect on an AT tire but not annoying. Overall, despite the hit on efficiency, it looks better than the OE 21’s.

In my experience, you’ve gotta give the tires a while to break in. I saw a pretty major improvement on our Nokian nAT after a few thousand miles. Started off great. Went down a ton and have bounced back to equal to the stock ATs.

Hopefully that will be the case.

Also remember all wheel combos will take a hit in efficiency in cooler temps. More heat is used and the denser air causing more wind resistance. It would be interesting to see what winter vs summer trip efficiency will be to Yosemite and back.

Nittos have good snow capability when new. I had some 3 peak ATs but the soft tread goes away pretty quick and then the hard section is not so good in the snow.

Looks like an awesome trip though!

I had Nitto's on my Audi a few years back and noticed the snow traction was not near as good as Nokians. That's my go-to now and fortunately they fit my 22's.

Go big or go home?

Any update on efficiency? Which version do you have?

Did you have your vehicle calibrated for 20" wheels by Rivian? If not, then those efficiency numbers are off.

The previous s/w update allows owners to change the tire size themselves so you might want to re-run your test for another 1000 miles.
