Understanding the 235/45R18 XL size
In the size code 235/45R18, 235 is the section width in millimetres (about 9.3"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 105.8 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 26.3".
The load index 98 means each tire supports up to 1,653 lbs — about 6,612 lbs across a full set of four. The speed symbol W certifies the tire to 168 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.
Tread life and grip ratings
This tire carries a UTQG rating of 500 A A. The treadwear grade of 500 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 $176.40 per tire, a full set of four costs $705.60. That is about 9% above the average of the 155 tires we stock in this size, reflecting its position in the range. Backed by a 50,000-mile treadwear warranty, that works out to roughly $14.11 per 1,000 miles across the set.
