Respectfully request tire height 275/60 R15 'S

The best answer is, it depends on who makes it. Tires vary in height from one maker to another. They shouldn't, but they do. I have seen 275 60s vary from just under 28" to almost 29". The only way to know for sure is to go on the manufacturer's web site.......or a site like Tire Rack, and look up the tire height for a particular size in a particular brand, because each brand can be different for each size.
