Tire Circumference, not tread pattern, is the determining factor. Have the seller measure the distance around each tire.
Then you measure yours...they should be within 2% for proper operation of the RT4WD.
One CRV owner had a blowout on a newer CRV...got another Bridgestone Dueller (OE Tire) with the exact same tread...but the aftermarket tire was a different circumference! Caused some problems.... :nervous: Eventually the tire dealer had to order an OE replacement tire to make everything well...
