Show original supplier description
The GT Radial Champiro SX2 is an extreme performance summer tire engineered for enthusiasts who demand superior grip, traction, and control. The high-grip silica compound further enhances its ability to grip the road, making it an excellent choice for track days, spirited driving, and regular street use. Key features include a wide center rib for improved handling, traction, and braking performance, and dual shoulder blocks that enhance cornering stability and grip. The Champiro SX2 also incorporates a gradient step design in its central tread ribs to reduce heat generation, contributing to more predictable performance and potentially longer tire life. Available in a range of rim sizes from 15 to 18 inches, with aspect ratios from 35 to 50 and section widths from 195 to 265mm, the Champiro SX2 offers versatility. It carries a speed rating of W and has UTQG ratings between 200 AA and 260 AA. For the 235/40ZR17 90W size, the tire measures 24.40 inches in overall diameter, has a section width of 9.5 inches, and a maximum load capacity of 1323 lbs. A note from one retailer indicates that vehicles selected may not be compatible with aftermarket TPMS sensors, advising to enter a different vehicle if TPMS sensors are needed.
