About this deal
I personally chose to go with 18” for the winter (235/45/18) and a compromise between looks and protection for the summer with 19” and 245/40/19. Note that I actually increased my total rolling diameter by 1% but I don’t plan on lowering my suspension and I’m told that staying within 1% is ok (more than that is not recommended). It will mean that my speedometer and odometer are slightly off but it’s minor.
Tesla OEM wheel/tire specs and alternate fitments. Of all aftermarket wheel suppliers out there, I found T-Sportline does the best job of clearly communicating the important specifications and making it easy to buy wheels that will fit the Model 3 Performance. They have a great wheel guide with all the standard OEM specs and their alternatives here:Drainage grooves around mounting edge of wheel hub… apparently, some wheels don’t have these and moisture gets trapped inside the hub while mounting which causes oxidation over time. All that is needed is small grooves to allow any moisture to drain out and evaporate.
The good news is that for the last couple years, video quality included with your Android smartphone is probably top-notch.Wheel width vs tire width. As you can see in the calculator below, there is an “ideal tire width” for a given size wheel. If you try to put a tire on that is too wide for the wheel, you start to impact performance and appearance (and safety when you go outside the max). And if you try to stretch a tire to fit a wide rim, you can also have problems including rim rash! I recommend using the second/bottom of the two “ideal” tire widths shown for a given wheel size. That will give a bit more rim rash protection. I’m also told that different tires have more square profiles (like Michelin) and others more rounded/bubbled (like Pirelli) They show everything, including offset, centre bore for the hub, weight, lug nut specs, wheel load rating, etc.
