What sizes are close to 235/55R18?
Among common sizes, 225/65R17 (about 28.5 in) is within about 1.2% of 235/55R18 in diameter, and 225/60R18 (about 28.6 in) is within about 1.6%.
These are narrower tires, and one needs a smaller wheel. Keep any alternate within about 3% of the original diameter, and confirm it against your vehicle placard before you switch.
Should I buy used 235/55R18 tires in pairs?
Yes, if you can. Tires on the same axle should match in size, and ideally in brand, model and tread depth, so the vehicle brakes and corners evenly.
When you replace only two, many tire makers recommend putting the tires with more tread on the rear axle to help with stability in the wet.
