Description

The Sumitomo HTR A/S P03 tire, model ASP78, is engineered to provide a balanced performance experience for sports cars, sedans, and crossovers. Constructed with a silica-enhanced tread compound, the HTR A/S P03 ensures superior wet traction and long-term wear performance. The tire's innovative tread design includes 3D sipes, which increase the contact area with the road surface for improved bite and stability compared to standard sipes. This tire also boasts a W speed rating, capable of reaching speeds up to 168 mph. Key specifications for this tire include a size of 225/40R18, a load index of 92 (supporting up to 1389 lbs), an Extra Load (XL) rating, and a tread depth of 10/32". The approved rim width range is 7.5" to 9.0", with an overall diameter of 25.1" and a weight of 23.6 lbs. It features a black sidewall and a radial construction. Sumitomo backs this tire with a 45,000-mile mileage warranty.
