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
I have been running Sailun 637 for 3 years now they are a solid quality tire. Sailun's have been around for quite awhile now and I have yet to read a post from someone that actually owns them that is dissatisfied or had any issues at all. I am a totally satisfied with them. Every bit as good as the Goodyear. But almost 1/2 the price. Sailun's are truly game changers
