The fitment and load rating of the tyre will determine whether you need the 'SUV' version or not, so check with the tyre fitter. The CR-V is not an especially heavy SUV so it may not need that tyre type. Regarding all-season tyres, they are certainly worthwhile if you do find yourself doing journeys off the salted main roads in winter, and with more extreme weather conditions predicted for the future it's well worth considering. Most new all-season tyres perform pretty well in the summer now, too.
