[Lil' Sparky's owner]

I bought a Spark EV about 6 months ago. Love it. Took it to a chevy dealer and they tried to rotate the tires. Car would not move. That is how they figured out the EV has two different wheel sizes. Looks like I need to look further than a dealer to get the best information about Lil' Sparky. So I am here.

Same thing happened to me a couple years ago, dealer didn't realize the wheels were staggered. OEM has 185/55R15 on the fronts and 195/55R15 on the rears.

If you plug those numbers in on https://tiresize.com/comparison/ you can see the difference in width and height. It's a taller and wider by about a pinky finger.

Thanks for the website! I figured the difference would not be that much since the chevy guys did not notice it at first.

The problem isn't the tires, it is the rims (metal wheel thingies). The front and rear *rims* are different sizes (I think that the front ones are smaller, but not 100% sure). If you can buy used front rims, you can put them on the back. The 185/55R15 and 195/55R15 *tires* have the same load capacity, so you can run 185/55R15 all the way around. (In fact, I put 185/55R15 on all 4 tires when I replaced them, since I couldn't find 195/55R15 OEM tires *anywhere*.)
