Mickey Thompson | Street Comp | 245/45R20 | ultra-high-performance street radial | Extra Load (XL) | Sold individually
The Street Comp is an ultra-high-performance street radial for modern muscle and Pro Touring builds. Its asymmetric pattern and responsive casing aim for predictable cornering and steering feedback, with compound tuning for dry and wet road use. For 245/45R20, the listed overall diameter is 28.7 in. and the tread width is 8.6 in.; these measured figures help compare fender clearance and the actual working tread. It is approved for 7.5–9.0 in. wheel widths and a 8.0 in. measuring rim. The 9.5 in. section width describes the casing at its widest point, which is different from tread width.
