The sticker inside the driver's door is still the final word, because trim and wheel package can change the size. Back to every Lamborghini Urus size.

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.
What the numbers on the sidewall mean
A 315/35R21 tire is 315 millimeters wide, its sidewall is 35 percent of that (about 4.3 inches tall), and it mounts on a 21-inch wheel. That works out to an overall diameter of roughly 29.7 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.
Our three picks, side by side
One tire at each price level from what the retailer stocks in this size, with the mileage warranty and UTQG grades as published by the manufacturers and their retailers. Treadwear is the number to compare: it is a relative wear rate, so 700 should last roughly twice as long as 350 on the same car.

Of the 35 tires listed in this size, 30 are in stock today. The lowest price is the Crosswind Ultra Sport Plus at $168.96, a 111W tire. The median is $464.99; a third of the tires cost $424.99 or less, and the top five percent start above $871.99.

Winter on an SUV in this size
Most SUVs in this size are all-wheel drive or four-wheel drive, which is enough to satisfy Colorado's Passenger Vehicle Traction Law on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, as long as the tires have at least 3/16 inch of tread. A two-wheel-drive version must instead be on tires marked M+S, 3PMSF or rated all-weather by the manufacturer. Fines start at $130. Four driven wheels help you pull away, not stop: a heavy SUV on worn all-seasons needs much more road to brake on snow than the same vehicle on a tire with the 3PMSF symbol, so in the snow belt choose the tire, not just the drivetrain.
None of our picks in this size, the Atturo AZ850, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

- Lamborghini Urus (2019-2024, 21 in rear)
- BMW X6 (2020-2024, 21 in rear)
Other years and wheel packages of the same models came on 255/50R19, 275/40R20 or 285/45R21 instead, so read the placard inside the driver's door before you order.

Frequently asked questions
How much do 315/35R21 tires cost?
Expect $169–$425 per tire for a budget brand, $425–$585 for a mid-range tire like the Yokohama Advan Sport V107, and $585–$872 for a premium tire like the Goodyear Eagle F1 All Season. A set of four therefore starts at about $676. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 315/35R21 tires?
315/35R21 is original equipment on Lamborghini Urus (2019-2024, 21 in rear) and BMW X6 (2020-2024, 21 in rear), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 315/35R21 tire?
For most drivers our mid-range pick, the Yokohama Advan Sport V107, 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 Goodyear Eagle F1 All Season is worth the extra. On a tight budget the Atturo AZ850 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.
