Your preferences may vary of course. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  Not saying there's anything wrong with 235...just that there's really no reason to avoid 245 on this car either.I'll also mention our other Tesla came with 245mm on 8.5" wide wheels from the factory, and so did my last ICE car.  Very normal tire width for 8.5" wide wheels.</blockquote>
