* Maintains block stiffness and distributes contact pressure evenly for exceptional grip* Flexible inside compound hugs the road surface to maximize grip in wet and dry conditions* Rigid outside compound resists deformation to boost cornering performance* Delivers optimal contact during acceleration, braking, and cornering* Reduces strain at the sidewall for better cornering traction

Understanding the 315/30R21 XL size

In the size code 315/30R21, 315 is the section width in millimetres (about 12.4"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 94.5 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 28.4".

The load index 105 means each tire supports up to 2,039 lbs — about 8,156 lbs across a full set of four. The speed symbol Y certifies the tire to 186 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

What the Toyo Proxes Sport 2 is built for

The Toyo Proxes Sport 2 is a summer tire, tuned for maximum dry and wet grip in warm conditions; it is not intended for near-freezing temperatures. Run-flat construction lets you keep driving a limited distance at reduced speed after a loss of pressure. Fitment category: Passenger Car, CAR, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 240 AA A. The treadwear grade of 240 is a relative durability score — a grade of 200 is expected to last roughly twice as long as a grade of 100 under the same controlled test. Traction grade AA measures straight-line wet stopping grip (AA is highest, then A, B and C). Temperature grade A reflects heat resistance at sustained speed (A is highest).

Price and value

At $304.16 per tire, a full set of four costs $1216.64. That is about 39% below the average price of the 26 tires we stock in this size. Backed by a 25,000-mile treadwear warranty, that works out to roughly $48.67 per 1,000 miles across the set.
