Im more of a 37" tire guy, are we going to need a lift kit or will these squeeze in?

  • From all of us at Scout Motors, welcome to the Scout Community! We created this community to provide Scout vehicle owners, enthusiasts, and curiosity seekers with a place to engage in discussion, suggestions, stories, and connections. Supportive communities are sometimes hard to find, but we're determined to turn this into one.

    Additionally, Scout Motors wants to hear your feedback and speak directly to the rabid community of owners as unique as America. We'll use the Scout Community to deliver news and information on events and launch updates directly to the group. Although the start of production is anticipated in 2026, many new developments and milestones will occur in the interim. We plan to share them with you on this site and look for your feedback and suggestions.

    How will the Scout Community be run? Think of it this way: this place is your favorite local hangout. We want you to enjoy the atmosphere, talk to people who share similar interests, request and receive advice, and generally have an enjoyable time. The Scout Community should be a highlight of your day. We want you to tell stories, share photos, spread your knowledge, and tell us how Scout can deliver great products and experiences. Along the way, Scout Motors will share our journey to production with you.

    Scout is all about respect. We respect our heritage. We respect the land and outdoors. We respect each other. Every person should feel safe, included, and welcomed in the Scout Community. Being kind and courteous to the other forum members is non-negotiable. Friendly debates are welcomed and often produce great outcomes, but we don't want things to get too rowdy. Please take a moment to consider what you post, especially if you think it may insult others. We'll do our best to encourage friendly discourse and to keep the discussions flowing.

    So, welcome to the Scout Community! We encourage you to check back regularly as we plan to engage our members, share teasers, and participate in discussions. The world needs Scouts™. Let's get going.


    We are Scout Motors.
Published range numbers will become an important consideration for buyers (once the configurator is launched), so if Scout Motors offers 2 or 3 different OEM tire / wheel combos, buyers will make different buying choices based on estimated range and efficiency numbers that get published, and what their unique requirements are.

Of course the industry pundits will do their testing, and there will be a bunch of YT videos comparing OEM tire and wheel options (certainly between the pure BEV and Harvester). Using Inside EV's as an example, they took all of the possible combos for Rivian and published this range comparison which includes motor, wheel and pricing differences:

With Scout, I would envision the comparison between pricing, range and configuration will be really interesting (based on offering BOTH the EREV and BEV). With Rivian, the comparisons were pretty interesting when comparing Quad VS Dual motors. *** This chart is out of date since there is now a Tr-Motor variant too, but looking at pricing, and if you don't need all the performance characteristics of the Quad, you can essentially get slightly better range on a 20 AT wheel & tire combo in a dual motor for $17,750 LESS COIN. However, Rivian was also packaging more features with the higher level trim / Quad variant too.

Again, my only point being that whatever Scout drops for OEM tires and wheels will be a consideration for many buyers when it comes to efficiency. So, there is an advantage to Scout making the truck capable of accommodating larger tires BUT not necessarily offering highly inefficient tires as an OEM option straight out of the gate (if the efficiency hit is large). I remember the Hummer EV getting hammered for being so inefficient.

Also - Being inefficient doesn't always equate to less range! If you have a massive battery pack (like Hummer) you can still get decent range, but it will come at a higher MSRP and higher charging costs:

 
I had a bunch of text here, but it was mostly esoteric and with lots of caveats, so I decided to just delete most of it.

TLDR:
Going from 33” to 37” is likely to involve a loss of range of up to about 25%, maybe more.

In @R1TVT table above, you can see a range loss of 13% due to change in wheels from 21” to 20” and change in tire diameter (33” to 34”). This is caused by increased rolling resistance, the increased rotational moment of inertia due to higher mass at the extremes of the mass distribution, and slightly taller vehicle.

For off-road travel, you can expect losses to be higher (compared to similar speeds for on-road travel, not compared to highway speeds). Especially if you’re deflating the 37” tires. The increased rolling resistance, increase contact patch size, etc., will have an increased impact. I would guess you could lose 50% efficiency (again, compared with similar speeds—wind resistance is negligible when you’re in situations of extreme tire deflation). This may matter to some people.

I don’t change my tires or tire pressure while doing very mild off-highway travel. If I’m just running forest service roads and not doing a lot of stop-and-go type off-roading, I see an increase in range. But if I’m climbing hills and digging through sand and rocks, I see a decrease in range of about 5%, sometimes 10%.
 
I guess my experience is a bit different and perhaps some of it has to do with my driving style (grandma most of the time, NASCAR only when needed for safety or soul). 2018+ Jeeps in Rubicon trim can fit 37s in stock form on the road and require the tiniest of lift depending how rowdy you get with them off pavement. With 4.10 gearing from the factory I have never felt regearing to be necessary even when towing a 7,000+ pound trailer. I did choose one of the lightest 37s I could find at the time (72lbs I believe, which is something like 5 lbs heavier than OEM). Perhaps my driving style, lighter tire choice, and constant tire pressure monitoring is what typically keeps me in the neighborhood of 17-20 or so mpg. One of my last tanks was 21.7mpg without a ton of highway miles, although I did put premium in on that tank. Still surprises me how well it does. I hear of others with the same vehicle and 37s doing MUCH worse, but I don’t know the details of their setups.

I think one of the main reasons tires matter so much more on EVs than gas vehicles is that gas is already so inefficient that the changes in tires aren’t going to show up.

A gas engine loses about 79% of the energy in a gallon of gasoline before it even moves the vehicle. So a loss of 5-10-25% due to rolling resistance won’t be felt because it’s no more than 25% of the energy that gets to the drivetrain (or 25% of 21% = ~5% or less).

Oh I have faith in Jamie. He’s been with Scout since the beginning. I can’t wait to see the Terra and Traveler now. Maybe 😎is our Easter Egg??

I’m totally a Switfie. Taylor has trained her fans to look for Easter Eggs. 😹
I wasn't referring to Jamie. :) I was saying someone may have been speaking prematurely.

It was just a cough. I’m sure it wasn’t implying the Terra update will have 37’s and be rigged up alike a Baja contender-that’s just my crazy pipe dream since there’s been heavy focus lately on the Baja campaign. Fingers crossed
 
Yeah but what about the Traveler. It could get 37s!! Right, right?!!!
I don’t know. Based on some others and being NYC I like a more urban feel, 35’s or 33’s and maybe no tire carrier (even though I know we both like it but seeing a new color and no carrier would make it more viable in more urban areas-parking spaces and garages way easier to contend with. I am interested to see how it looks without carrier even though I I tend to have the spare carrier. Guess we will find out soon. And I will get pics up close and personal 😀

You better!! If it wasn’t such a long drive I would be there myself, dragging my husband and his camera behind me. I have high expectations!
 
I more concerned if the steering rack - tire rods - drive by wire systems -motors -axels are strong enough for upsizing off-road tire for 37 etc
The drive-by-wire and motors aren’t a concern. But the mechanical components (axles, CV joints, tie rods, etc) are always a concern when upsizing, just like on ICE vehicles. As mentioned by @Chavannigans earlier in this thread, upsizing to 37s can easily result in missing $40k from the bank because of the need to upsize critical suspension, steering, and other components.

I had no idea it cost that much! 37s look great but not at that cost for me.
