About the 315/35R21 size
Urus rear on the standard 21 in wheel, with 285/45R21 up front. A handful of models exist and all of them are made for the car's weight and speed.
The numbers mean: 315 mm section width, sidewall height 35 % of that width, and a 21-inch rim. Overall diameter works out to about 29.7 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.

Frequently asked questions
How much do 315/35R21 tires cost?

What is the best 315/35R21 tire?
For most drivers our mid-range pick, the Pirelli P Zero (PZ4), 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 Michelin Pilot Sport 4 SUV is worth the extra. On a tight budget the Continental SportContact 6 is a sound choice.
Can I replace just one or two 315/35R21 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.
