Following. Please update on the comfort/range/noise/performance. Been looking for AS tires.

Going on:

Those look rally great. Looking forward to seeing them on the R1.

 

[ksurfier]

Very soon…

 

[RivianWonderer]

Very soon…

Need more updates!!!!!

 

[RivianWonderer]

Really want to see the range KWH readings. Also the noise/comfort on those tires.

 

[ksurfier]

Detailed review tomorrow AM, will run the tests again in a week or two, should have at least 500 miles on them by then…stay tuned…

Initial thoughts:
Driving in Sport Mode is significantly improved. The “bouncy” feeling is essentially gone. Road feels more connected and overall a more stabilized and controlled driving experience. Pretty limited data but so far seems it’s at least as efficient as OEM 20” Pirelli. More to come but wanted to share first impression.

Tempting. But, not available in stock 20” size of 275/65r20. Don’t really want to deal with the calibration change from 34” to 33”.

I assume you started with 21” then made the switch to 20”, thus the 60 profile.

“ …least as efficient as OEM 20” Pirelli.”

Calibration? My OEMs were 2 mph off, these are 3 mph off…

Computer can’t tell difference…never had the 21”, but been thinking it’s a great time to pick up a set since nobody wants them..oh wait, they 48# each…

At 65 mph the Geolandar CV 4S was 2.14 MPK, 55F and no wind in All Purpose. Tires are new so hopefully will improve. Guessing they will be about 5% more efficient than the OEM.
No distance adjustment was needed. At 40 mph they are around 5% more efficient. The better ride/handling is the best part for sure.

What is frame of reference, the larger OE ATs? Odometer and trip computer would be off without reprogramming (if original equipment was the OE AT).

What is frame of reference, the larger OE ATs?

Yes 20” OEM, realizing how bouncy they were, driving in sport mode wasn’t possible, now it is. CV 4S seem like a great tire that checks all/most of the boxes…obviously not a hard core off road tire but neither was the OEM.
