About the 285/55R20 size
Popular no-lift upsize (32.3 in) for 20 in half-tons; LT load range D/E and some P-metric. A/T, R/T and hybrid-terrain patterns.
The numbers mean: 285 mm section width, sidewall height 55 % of that width, and a 20-inch rim. Overall diameter works out to about 32.3 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

What is the best 285/55R20 tire?
For most drivers our mid-range pick, the Toyo Open Country A/T III, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Nitto Ridge Grappler is worth the extra. On a tight budget the Ironman All Country M/T is a sound choice.
Can I replace just one or two 285/55R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
