I just got a 2018 SQ5 with 21inch. I want to install 265/40/21. Please let me know if there is any problem to install it.

Thank you!

1010 Tires has a tire size calculator that shows the impact of different tire sizes. Looks like your speedometer will be off by 1.5 mph (too slow) at 60pmh. You'll be increasing the overall diameter of the tire by 1/3 (.32) of an inch.

I have 265 40 21's on currently for winters. I also test fit summers (pics/info below):

No rubbing at all without spacers? Thank you!

I am running 265/40R21 Pirelli Scorpion Zero All Season Plus. No problem. Options are very limited as you know and this was the only A/S tire I could find that mentions use for light snow use. They perform okay in the dry. I do feel a little drift compared to the OE summers. But that is to be expected. I do drive the car hard though when I see that.

Hi Batman -

No issues on this end at all (no spacers, zero rubbing). I have the air suspension as well (so may sit a bit lower).

Good Luck,
tgt

Sorry Batman, I cant figure out how to post pictures. It just goes grey screen on both my PC and Ipad.
The tires fit and look good. They pretty much are your only option.
