Understanding the 255/40R19 XL size
In the size code 255/40R19, 255 is the section width in millimetres (about 10"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 102 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 27".
The load index 100 means each tire supports up to 1,764 lbs — about 7,056 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 Goodyear Efficient Grip ROF is built for
The Goodyear Efficient Grip ROF 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, Performance, HP.
Tread life and grip ratings
This tire carries a UTQG rating of 340 A A. The treadwear grade of 340 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 A 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 $443.24 per tire, a full set of four costs $1772.96. That is about 107% above the average of the 89 tires we stock in this size, reflecting its position in the range.
