Just for info I ordered set SAILUN 637 G load tires for friend and this size is almost identical in diameter size of the GOODYEAR 614. 30.7 inches so good option to consider
It looks like my credit card was charged $889 for FIVE tires WITH wheels. That was about $79 shipping included I guess. They are arriving today at the garage I had them sent to. With the shipping in there they come out to be $178 a piece, and that's with the wheels too of course.
