    Okay who has really thought about doing this?
    How close have you landed to this?

    I have seen lot of lowered prius but I've yet to see one that is setup for off roading!
    Why? why not? :)

    High lift jack, LOL. CV joint angles would be extreme and probably need to be changed with each oil change or sooner. Very little articulation/flex but great approach and departure angles.. Power would be sucked up by the large diameter heavy rotating wheels and tires. Definitely a conversation starter.

    I'll stick with my 4Runner TEP. ;)

    We've done a lot more than just THINK about it! ;) Everything was designed to keep cv axle, ball joint, and tie rod angles within an acceptable tolerance. We put over 60k miles of abuse on our original 2013 prototype platform and are still on original EVERYTHING including battery and brake pads at 220k miles (with the exception of the struts and shocks which we replaced when we installed the kit 60k miles ago.) With just the 1.5" lift we aren't seeing any noticeable reduction in mpg and a MASSIVE increase in drivability. No more scraping bumper on driveway approaches, parking curbs, speed bumps, etc. With a 215/70R15 all season tires the MPG get reduced by about 5-7% but its well worth it in our book. Hard to find something comparable that still gets 43-45mpg.
    Our 2019 AWD-e is an absolute blast to drive with the lift and 205/75R15 General Grabber AT2 tires. Once again with just the lift we saw no reduction in MPG and minimal power reduction. With how large and aggressive the tires are and how soft the rubber compound is it takes its toll on MPG though, bewteen 10-15%. We will most likely swap out to a less aggressive LRR all season tire in a 215/70R15 after winter to get those numbers back up but the combination of the lift, tire, and awd is incredible, especially in snow. :) Email Photo.jpg IMG_0977.jpg Prius Prarie (1 of 1).JPG image.jpeg image.jpeg image.jpeg

    Awesome. On my 2017 Prime, I ran for 63K miles on a set of 205/65R15XL 99T Michelin X-Ice 3 snows that I installed when the car had 700 miles on it. I bought an extra set of wheels to swap summer/winter tires twice a year. But the snows handled amazingly even in Arizona well over 100 degrees out while driving through Salt River Canyon like Mario Andretti, so I kept them on year-round. That they lasted 63K miles was unexpected, but the tires are 10 load ranges above stock, they're expecting the weight of a minivan, and I run them at 50psi, so they barely feel the weight of the car on them. The 6.5mm lift from tire size (plus quite a bit more from 50psi inflation) made a noticeable difference in where I could go without trashing the car's body. I drove it up to some powerlines on a rocky Jeep trail high above Arco, Idaho, for instance. I wouldn't advise that for everyone, but the car and I came out of it unscathed.

    When their tread was finally gone, I decided to try 205/70R15 X-Ice3. A guy with an old CR-V was moving from Maine to San Diego, so for the first time in my life, I bought used tires. $100 tires for $40ea. He had one winter on them, they were in great shape. So the tire lift went from 6.5mm to now 16.75mm. The taller sidewalls do take away the perfect handling, but they're still fine and corner well, just a little more body roll and some squirming in strong crosswinds.

    I'm considering a small lift, now that I'm planning to do some camping in the Prime, out west. Angle of approach is not the Prime's strong suit, but just raising it a little has made a big difference in where I can go and what I can do.

    This thread is of great interest to me, living where I do and going where I go. I too use mine for getting to places to ride. The one thing about the Prime I really didn't like is it's lesser ground clearance, my '13 PIP is bad enough on rough roads.

    I just bought another set of Ice X's for my '13 PIP, after getting 47 K miles out of the first set. Left on year round, all 4 at 45 psi, and rotated every 5 K miles. The tire shop remarked on the very even wear.

    I am pretty sure I am buying a '19 Prime today, and it HAS X's on it already! 9 K miles.

    That's not bad, especially when I assume yours were the stock 195/65 size, while mine were both oversize and XL rated.

    I rotate my tires only once per set, at the point where I guess is halfway to their being worn out. If an alignment problem is causing odd wear, I'd rather find it sooner rather than later. While rotating (front to back only, these are directional tires than can't be swapped left/right) spreads the problem across two tires, it also hides the problem for twice as long before you can notice it and diagnose it. You have to do a certain amount of bad stuff to a tire before noticing it. I'd rather do that to one tire than two, plus find the problem sooner. Having said that, I've had a 2001, 2005, and now the 2017 Prime, and never had uneven tire wear, an alignment problem, or even an alignment performed. after putting 80K on each of those, with the 2005 being the only one bought used, at 151K.

    A second reason I stopped rotating tires long ago, is that on some cars, the brake rotor's exact center of rotation relative to the brake pads, is determined partially by where it's at when you tighten the lug nuts, not being perfectly located by the wheel bearing/hub assembly. I had a GM minivan where even just loosening the lug nuts, jiggling the wheel around around and tightening it back up, it would make the brake pads scrape a different track into the rotor. Extra noise and wear for hundreds of miles. So I learned to leave well enough alone, and only rotate once so that all 4 tires wore out at the same time.

    Can you post a closer pic of the sidewall of the AT2 on your prime.
    How's it handle on the freeway?
