Is anyone running 245/40/19's on the stock wheels?

I'm assuming no issues vs. the 235/40/19's other than a slight speedo difference, but just seem like much more options with the 245 series tires.

Yep, lots of people.

I'm running them, no issues.

There is a software to get the speedo right when changing the tire dimension/wheel size. 245/40-19 is about two sizes too big though, even 235/40 is and I don't know why Volvo specifies that, or if they just were lazy.

Yes, Volvo as an application for various wheel sizes.
VDASH can also do it under ''Wheel and Suspension - Rolling Circumference''.
I have not checked the price however.

Yes, I run that size with zero issues. I didn't bother with the speedo change. It's minimal.

Do you have details on such software? I have not been able to get my car updated to read correctly with my 245/40/19 tires/wheels.

Last I heard VDASH did not work either as the TCM(may not be remembering correctly) threw an error if you attempt to make the change.

In any case it is about a 5% difference vs the stock 235/40/18s and easy to keep in mind while driving

Brought my car in to try that at the dealer after finding that in VIDA but was told it showed as not compatible. I'll have to check the next time I am in
