You should find a LOT of recommendations (and experiences) on tires. For example :

I have 195 45 15 proxes t1r on all 4 corners with helium 6.5 x15 rims 7 lbs lighter per corner than stock I'm doing some test to compare range per kwh with stock rims and tires. But this set up gets rid of plowing and makes the car way more fun at the expense of slightly rougher ride and noisier tires

On the stock rims I have original tires on rear and ecopia 422 plus just installed will update on my findings

And yes I will compensate in my calculations for smaller diameter tires
 
With the 195 45 15 proxes I get 5.58 mi / kwh on a certain round trip. This is compensating for tire diameter (actual on display was 5.74mi/kwh)

With brand new ecopia 422 up front and stock not new tires in rear I get 6.5mi/kwh on same round trip

All this is with no AC or heat FYI

Supposedly as the ecopia wear my mileage should increase we shall see
 
Come on. Race tires. And your running efficiency models? Take out the abs fuse and tell me your g forces instead. And can anyone tell me if my 195/65r15 tires are going to fit in the rear? If 215/45r17 on et40 fit. I think 195/65r15 is smaller. For sure not on the front. Biggest I’d run is 205/50r15.

I wonder if I will have to drop the rear to match the front after adding the larger tires in the rear. Can anyone recommend something beside. 0010/250/0300. 10inch 2.5 ID 300lb/in.

And what size washers to add camber to the rear. And if it would be possible to zero out the tow in the rear with a washer. I’m getting outside should wear in the rear. Maybe low profile tires are in order. 195/45r15. Is the smallest tire sidewalls available in 15. In truth . I’d rather run 14s
 
In the front it’s overall diameter that more the problem than width. The spring perch and the inside fender offer interference. Width? Just add a spacer and roll the fender.

I wonder if a 2014 with the altered suspension for the new battery pack replacement will have the same geometry...

I seriously question that anything needs to be done to 'the suspension' if a '14 were to qualify for a replacement pack and they gave you a pack from a '15 or '16.
What could the weight difference be?
Where is it written that all this extra work is required?
The weight difference would not be more than having 3 of your LARGE in-laws sitting in the car. :cool:

Side note: Has there been any reported pack replacements under warranty from degradation?
 
The issue in the front is overall diameter more so than width. Interference is provided by the inside fender and the spring perch. Width? Just roll the fender and add a spacer.
 
Installing 185/60R15 tires on the front of a vehicle means using tires with a width of 185 millimeters, an aspect ratio of 60%, and designed to fit a 15-inch wheel diameter. This tire size can impact handling, grip, and ride comfort, and it is important to ensure it is compatible with the vehicle's specifications and requirements.
 
The issue in the front is overall diameter more so than width. Interference is provided by the inside fender and the spring perch. Width? Just roll the fender and add a spacer.
So 5/16" taller than a 195/55 up front is too much for my 2015 Spark 2LT EV?

I'm not concerned about the width, I would like some tires that do 5-6 miles a kw rather than 3.0 miles a kw like my current V-rated Achilles ATR Sport tires do.
 
Ok I think I came up with a solution to a 185/60r15 tire on a Spark EV on the front, they have these for the back too, a strut lift kit by Spaccer, to me it's currently $305.66 from Germany, this includes a 12mm spacer and a 3mm rubber spacer, note the amount includes shipping and is subject to change since I'm going to pay in Dollars and Spaccer will get paid in Euros. Both provide 0.59" lift and as many as 4 can be stacked, but the cost goes up as each is custom made and is not off the shelf.
 
I use 185/60-15 on all four corners. Works great, no issues beyond a 3% higher top speed and actual miles traveled being 3% more than what the odometer shows.

I mounted them on a set of wheels from a gas Spark.FB_IMG_1717333801761.jpg

A better solution is a Tema4x4 front strut lift kit in either 20mm or 30mm, they come with nuts, bolts, and spacers and are on ebay and all that I mentioned requires an alignment. On ebay the kits are $124.00 and $139.00 respectively. There is a 30mm kit for $99.00 but it is just 2 spacers. Spacers also should solve scraping from a steep driveway.
