That size could be weak in the load carrying capacity. Typically 95 or maybe
96 load index. Make sure it is rated for inflation to 44 psi and you should
be OK.
A 215-70-15 will put you into a 98 load index which is more than ample.
However this is almost a 27" tall tire (stock is 25.5") and this much change
is noticeable for the gearing and braking.
The 15" wheel is the hardest to get properly rated tires while maintain a
reasonable diameter.
Depending on planned use you may want to consider a tire more designed for
highway handling or winter use.

Was thinking of getting some of these to go on my Westfakia. 205-70R-15.
Anyone have any feedback they would like to share. Thanks. Merv
