Aftermarket Wheels for CT5-V Blackwing

[1Evil55]

Pardon my ignorance. When changing wheel and tire sizes is there any effect on the speedo, transmission or other devices that determine maint based on mileage. I have purchased aftermarket wheels for my other vehicles but always kept the ratio as close as possible ( reduced tire sidewall to compensate for larger wheels etc. using an online sizing tool.) Does the BW use the same type of tech and is overall sizing a factor with the mileage etc? PFA previous vsport went from 18 inch to 19 inch wheel but changed tire size to keep almost the same circumference

It boils down to the OD. As long as you don't change that you won't have any issues related to your speedo.

Yeah, so best bet to shoot for the same overall diameter compared to stock. My rule of thumb is always close to stock but never over 3% difference. I use a wheel offset calculator and tire calculator to figure out what is stock and compare the sizes im going for. For the most part, my specs are like .7% within the stock specs iirc.

yes I planned on using the wheel tire comparison tool. Just wanted to make sure it was still required in case they had some new tech I wasn't aware of on these cars.
