@omarsultan Thanks. Not sure on the tires since I do not know the new sizes that will be on the refresh version. Went to 22" on last rover and found teh sweet spot on psi to give a good ride, Have a dedicated 20" set for winter but have not used winter tires in two winters. Found that even though the winter tires made it unstoppable, the good A/S I have been worth the loss of hassle to change out.
If I find that I need to switch out or there are issues with the 21's - I will probably go 20" There are great choices at 20" and they are cost efficient.
