How different setups will affect the Model Y’s Performance and Range:
Before we get into fitments, we first want you to have a firm understanding of how different fitments will affect your Model Y in regards to Acceleration, Braking, Handling, Comfort, and Range (if you would like to read the details & physics explanations of how different wheels affect your Model Y you can learn all about it in the “Physics Reference Section”). We want to consider each of these factors in regards to how you will be using your Model Y and what you want out of your new wheel setup. The factory wheels and tires were selected for a balance between all 4 of those categories. The 255 wide tires provide a decent contact patch for performance while offering limited rolling resistance to keep your range respectable. Unlike the Model 3 though, the Model Y has a narrower range of potential sizes between factory and maximum capacity.
For Fitment’s Sake: Only Looks Matter
Some enthusiasts want to run a specific size wheel and tire combo to achieve a very specific level of fitment, or to achieve a wider wheel and tire setup than everyone else. These fitments typically have an adverse effect on performance, but the owners don’t seem to mind (or at least say they don’t). With this in mind, before you pick a fitment just because of the way it looks you should be aware of the downsides.
Because of the limited size options between factory minimum widths and the limit of how large you can go, we probably won’t see a lot of fitments that would be considered extreme. That’s not to say someone won’t tell you that you can run an 8” or 8.5” wide wheel on your Model Y, but most people have the common sense to not try to downsize from factory specs that far. Especially on an SUV that weighs over 2 tons. I’m sure you will see some Model Y’s running around at one point that have been slammed and running crazy stretched tires. Just keep in mind that if you like that type of look you probably need more detailed and specific advice than this blog will cover.
Form and Function: Performance and Good Looks
Many enthusiasts fall into this category and make up the majority of the customers we see. These setups are all about balance between form and function. This doesn’t mean these setups are not without their drawbacks, but they will tend to be more acceptable.
Modest Plus Sizing:
An example of this would be something like a 20×10 square setup (same size front and rear) with a flush offset (see fitment guide section for offset references). The majority of Model Y’s come with 19 or 20 inch wheels which are already a decent diameter but a little wider never hurts. A 19×10, especially in flow formed or forged construction, gives you a nice balance of weight, width for wider tires, and improved fitment to look flush and aggressive. The only drawback of a setup like this is possibly a slight decrease in range (see why in our Physics Reference Section). However, you can also use your stock tires (or stock size) with such a small increase in width.
Another example of this would be something like 21×10.5 front and 21×10.5 rear with a flush offset for the Performance Model (see fitment guide section for offset references). Again this gives you a nice balance of weight, width for wider tires up front, and improved fitment to look flush and aggressive. The increase in tire width up front offers some additional balance in performance and makes it easier to find matching concave profiles for the front and rear.
Practical and Stylish:
If range is your top priority and you want to be as efficient as possible but you still don’t want to have your car look like every other Model Y out there you have a lot of great options.
Sticking to a Factory size or 0.5” narrower with a flush offset (see fitment guide section for offset references) is a great option. You can keep the same size tires that normally come equipped on a Model Y, but you can save extra weight by choosing a flow formed or forged wheel which will improve your range and even ride quality. If you do not increase your wheel diameter you can easily reuse your factory tires for cost savings. When you are ready for new tires you can also go the “extra mile” and select something with a low rolling resistance for ultimate economy like the Michelin Energy Saver A/S. The only drawbacks here will be no improvement in traction for performance and some negative impact on handling.
