Bob, I saw the gears also, great to see them available. You may want to to to one of the tire sites such as Tire Rack, www.tirerack.com and check tire heights for different sizes. I checked a couple, I also have the 255/60/15 tires on my car. BF Goodrich T/A Radials 255/60/15 = 27.1 inches high 215/70/15 = 26.8 inches high Firestone Indy 500 255/60/15 = 27.1 inches high 215/70/15 = 26.9 inches high It appears there is a natural variation between brands for the same size tire. It looks like the SG035 may be a close match but for the price you could even get a size up and down also if you thought it was necessary. Good Luck Dennis C.
