22” vs 20” Wheel Comparison - Real World
There are so many examples of the opposite effect of tire weight, LL75 is getting better efficiency with 20ā General Grabbers than the 21ā OEMā¦could you provide one 15-minute constant speed test to support your claim? Check also Anthonysfl, 20ā Pirelli AS+3 got something like 350-360... -
22” vs 20” Wheel Comparison - Real World
?????????????????? Mass and Inertia: Reducing the weight of the tire decreases the energy required for acceleration and maintaining vehicle speed. MORE EFFICIENT! Deformation: Lighter tires may deform less under the vehicle's weight, leading to less energy lost as heat when the tire flexes... -

Need sticky, quiet 20's!
Recommend checking tirerackā¦ ā January 27, 2024 3.9 out of 5 I returned these tires and got Continental TerrainContact HT instead. The Platinums were smooth, quiet, and didnāt transmit noise from control joints or train tracks. However, on snow covered Michigan highways, they didnāt inspire... -

Affordable high efficiency 20" wheels and 33" tires options (275/60R20)
Going to be next to imposible to find 22 inch tire that lasts more than 10-15k miles too, so really expensive if you stick with OEM pirelli's... I also think 22s and good (high MPK) tires can't coexist...if you are in it for the aesthetic factor, then you prob. don't want the boring/bland high... -
High efficiency 20" wheels and ~34" tires options (R20 - 285/60 - 275/65 - 285/65 - 295/65)
Any update on your tires? They look really great! Did you find a lower pressure that works? -
Affordable high efficiency 20" wheels and 33" tires options (275/60R20)
Haven't bothered since the consensus indicates that people with 21/22" tires are removing them and installing 20". The only reason for 22" tires is aesthetics, so at that point who really cares about treadlife, performance, etc.? In my opinion, an 8500# vehicle shouldn't be rolling around on... -
Tesla to Rivian?
While I canāt answer all those, you should find 99% with search function. Since there are different variants, it would come down to the range (400 mi vs 300 mi) and other factors. If in a rush charging to 60-65% is the best practice (same as Tesla most other EVs), obviously longer distances...- ksurfier

Tire rack says it is fine: https://www.tirerack.com/upgrade-garage/what-is-maximum-load-inflation-pressure-for-a-tire# Therefore, if the vehicle's recommended "cold" inflation pressures correspond with the tire's maximum inflation pressure, it will often appear that too much tire pressure is...- ksurfier

50-51 psi coldā¦if itās hot out then Iād make sure tires arenāt above 54-55. I might also do a 5-min 75 mph test at 46,48,50 psi to see if there is any difference. If thereās no significant difference then run them 48-49 cold. For the test, reset trip B once at 75 mph and take photo/reading...- ksurfier

A2Z NACS Adapter unboxing - what was lost is found!
Just tried it, worked great! Adding info aboveā¦ I'm also convinced that charging from 20% to 60%-65% is the sweet spot for roadtrips...gives ~2 hours drive time and then a ~15 min charge stop. -
A2Z NACS Adapter unboxing - what was lost is found!
Update - took it for a test run, worked great! Peak was 217 kwh (460 MPH) till nearly 50% SOC: Overall was 30 kwh added in around 10 min for essentially 6 miles added per minute. Making sure its charging via Tesla and not the Rivian account was the only minor annoyance, just have to confirm...- ksurfier
