1983 RX seven tire upgrade to Sumitomo HTR 200?

I'd like to upgrade the stock 185/70HR13 tires on my
1983 RX seven GSL. Rims are stock aluminum four spokes.
Tire Rack has a great deal on the Sumitomo HTR 200. Ideally I'd like to go with 215/50HR13. But other choices are
205/60HR13 or 195/60HR13.
Does anybody know if the 215's will fit? Thanks a lot.

I do not exactly know the rim width of the stock rim, but depending on the stock tire being a 185 it is probably 4" 5".

You could fit a 195 onto a 5", but not a 205 or 215. A 215 could best fit a 7" rim and may squeeze onto a 6", but you'd have lots of pinching in of the sidewall which could adversely effect handling.

GET YOUR TAPE MESURE OUT AND FIGURE IT OUT . They may so DUE NOT CARRY ANY MOER THAN YOU AND A INVISABLE AND WEIGHTLESS FRIEND WHEN YOU DUE GO ANY WHERE UNLESS YOUR GONNA DUE THE KONI SUSPEINSION KIT UNDER IT.
