Will the off-road tires reduce the range like 22s on MX?

[Xenoilphobe]

I agree it's going to take a hit with larger tires, My Supercharged FJ with 33"s and tons of gear on it can barely go over 200 miles when towing my off-road trailer, I think the Cyber truck will do a lot better and it doesn't drink 93 octane!

If i can get my hands on one she will be 150 miles a day of low grade clay roads with not much gravel, See how she goes!!! Im opting for the TRI motor because all the mud will reduce range big time i imagine. Im still debating this or a new JL Diesel. I really would like a CT to work for me though.

I have a Ford F-150 switched from stock tires 265/70R 17 to the same size in Toyo open country M/T 10ply/load E very aggressive deep tread. I lost 3 MPG, 22MPG to 19MPG at 70 MPH. A loss of 13.63 percent. The physics of rolling resistance, (see Mitchlen Tire "tools" Rolling resistance comparison). Increase tread depth, tire size, load rating, Load, all increase rolling resistance.
Add my tools, 95 gal diesel fuel tank for tractors. Now at load capacity around 7500lbs. MPG is down to 15MPG at 70 MPH a 31.81% loss.
I believe the Tesla pickup will be much efficient than the Ford F-150. These are the numbers I have to compare. Tires are Tires.

I would argue rolling resistance is a bigger part of Tesla's energy consumption, the aerodynamics of the body and aerodynamic improvements of drastically reduced cooling needs. So if making the same exact tire change on the Tesla I would expect a bigger efficiency sacrifice.

 

[3axlift]

I believe it will. Not everyone wants/needs the biggest offroad tires. Some will want road tires, some heavy duty trailering tires.

My bet: Road tires standard for highest range and quietest interior noise. All else optional with range degradation.

I would like believe that Cycberytrucks posted ranges are with aggressive offroad tires it was shown with. I have not seen these Goodyear tires before. I think Tesla asked different tire manufacturers to design a low rolling resistance offroad tire for the cycbertruck, Goodyear won.

yes, you would increase efficiency if you switch to a low rolling resistance street tire.
Use the reverse of my switch from Michelin 265/70R17 to Toyo MT 265/70R17. A lost 3 MPG, 22 MPG to 19MPG.
If cycbertruck was range tested/projected on paper to have a 300-mile range and switched to a light truck street tire, you should/might see an increase of 13.6% - of range 40.8 to 340.8

Why off road tyres as you’re hopefully never gong into places that require off road tyres

I live in AL where people love to hunt and drive on their properties. Heck, there are guys that build hill climbers and rock crawlers and take them “exploring” every weekend. My point is that loads of people look for opportunities to get off-road in their well equipped vehicles. Most just “jack up” their truck and never take it off road . Status symbol. If you think about it Jeep has built and entire platform of vehicles on getting off the pavement.

 

[RHINO SKIN SOL]

I would guess the Tesla range estimate is way above what we would see in real world driving. Just like the MY i drive or any other vehicle. Our MY LR Tesla estimate is 326. Driving like a normal human on the open road we see about 210 mile before we get anxious and the car would probably go 250 before dead. So i assume we can knock the Cybertruck range down by 1/3. This would still put it in a great road trip range. We got stretched out this weekend Winnemucca, NV to Hine OR. 300 mile highway range would be a game changer.

Elon did say 500+ miles. Hopefully its on the higher end of that number.

500 is a super heavy estimate. You Lucky to get 200 from the 320 estimate with those nobby tires.

 

[vcor]

The range testing is with the stock huge nobby tires, custom-made for Tesla. So 470 EPA (dual motor) with the range extender seems reasonable. With off-roading far slower than freeway speeds, you might get more range. The best range in an EV is at 35 mph or so - often 30-70% beyond the EPA range. If you go a lot slower (10-15 mph), then the range will likely be below the EPA numbers. Not sure how terrain would affect those numbers, but likely similar to any ICE car. Driving in mud or deep streams could really reduce range.

 

[SpicyPaneer]

I'm wondering if the 500 mile range of the tri motor will be subject to the *rated range reduced by 20% with these tires and rims language that the model X was subject to.

That'd be a real bummer, would hate to have to sissy up the CT to get 500 miles instead of 400.

Thoughts?

Only way to get 500 mile or near that is on a railroad track with no tires.

Then how did the Model 3 get 600+ range?

Loose snow on the roads reduced my model 3 range by 30-40%.

Modern AT tires don’t affect range at all. I have 0% deference between my summer tires and studded Nolan Hakka 9 in the winter with my model 3.

Wut?

WLTP testing… MAYBE.

Absolutely AT reduce range, chunky big ole tread blocks. You may be thinking of AS or all season tires on your 3.

My nokians are a dedicated winter, which are a more aggressive tread then most AT tires (see picture) and a very soft compound.

Don't those Nokian Hakkapeliitta 9's go on the car once the temps drop below 50° F? Doesn't the range drop in Lower temps? If you left them on in the summer your range would drop due to the softer compound.

The range drops in lower temps due to running the heat and driving on snow covered roads.

But when I swap to them in early October and from them in late May. Before the snow falls I notice no difference at all in wh/min on the Same weather, same drives, same roads.

UPDATE #3: Tesla Model 3 Sets New Range Record At 606.2 Miles

Well, the second Tesla Model 3 hypermiling attempt has come to a close and we're pretty impressed. These guys endured over 32 hours of driving a repetitive one-mile loop with cabin temperatures over 108 degrees at times.

LOLOLOLOLOLOL hypermiling != real life.

108* interior temps, yeah. That sounds like something every member of this board will do. Especially those that get mega sad that hvac pulls range.
