What sizes are close to 275/55R20?
Among common sizes, 265/70R17 (about 31.6 in) is within about 0.9% of 275/55R20 in diameter.
That size uses a 17 inch wheel and is often sold in LT versions, so it is a different tire for a different setup. Stay within about 3% of the original diameter and check your door placard and owner’s manual before any change.
How do I check used 275/55R20 tires for curb and bead damage?
Run your eyes and hand around the outer sidewall for scuffs, gouges or exposed cords from curbs. Scrapes that cut into the rubber, not just scuff it, are a reason to pass.
Then look at the bead, the edge that seals against the wheel. Tears, kinks or chunks missing there can cause leaks or a bad seal.
Check tread depth across the full width and read the DOT date. We mount and install what you buy, so stop by the shop.
