About the 325/30R20 size

Extremely wide 20 in rear. Made in single figures of models, usually to order, and a set is a four-figure purchase.

What the numbers on the sidewall mean

A 325/30R20 tire is 325 millimeters wide, its sidewall is 30 percent of that (about 3.8 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 27.7 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded.

Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.

Useful if your vehicle came with a different wheel package, or if you are comparing an upsize: the same tire usually costs more per inch of wheel, not per inch of rubber.

Winter and this size: summer tires are not winter tires

Many tires sold in this size are summer tires, and the manufacturers advise against driving them in near-freezing temperatures: the compound hardens, grip drops sharply and the tread can crack. They also carry no M+S or 3PMSF marking, so a car on summer tires fails Colorado's Passenger Vehicle Traction Law outright on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, unless it is all-wheel drive with at least 3/16 inch of tread; fines start at $130. If the car is driven year-round in a state with real winters, either run an all-season or all-weather tire in this size or keep a second set of winter tires, often on a smaller, narrower wheel that is also less expensive.

What is the best 325/30R20 tire?

For most drivers our mid-range pick, the Toyo Proxes R888R, 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 Pirelli P Zero (PZ4 is worth the extra. On a tight budget the Pirelli P Zero is a sound choice.

Can I replace just one or two 325/30R20 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.
