Summer racing tire for track use

The Mickey Thompson ET Street S/S is a DOT-approved high-performance summer tire built for racing vehicles. Its directional tread pattern and R-compound construction deliver strong dry and wet grip during competition. The 305/35R20 size fits a 20-inch rim with a 305 mm section width and 35 aspect ratio.

Sustained grip on hot pavement

The R-compound maintains consistent traction as temperatures rise through repeated hard launches and cornering cycles. Directional grooves evacuate water efficiently to preserve contact patch integrity in wet conditions. A tread depth of 6/32 inch provides the rubber volume needed for extended track sessions without rapid wear.

Street-legal limits of a racing compound

DOT approval allows legal highway travel, yet the summer-only compound loses elasticity in cold weather and offers no winter traction. The SL load range and absent speed rating reflect a design focused on maximum grip rather than load-carrying versatility. Buyers needing year-round usability or higher load capacity should consider alternative tire categories.

Questions about this item

How much road noise and heat should I expect from the 305/35R20 ET Street S/S during extended summer driving?

The directional tread design and R-compound prioritise dry and wet grip over quiet touring comfort, so expect noticeable pattern noise and rapid heat build-up during long highway runs.

What wheel width and vehicle clearance do I need to fit the 305 mm section width on a 20-inch rim?

You need a 20-inch rim of appropriate width for a 305 mm section, plus enough wheel-well clearance for the 28.4-inch overall diameter and 35-series sidewall.

Will the 6/32-inch tread depth on this DOT-approved racing tire wear evenly alongside older rear tyres on the same axle?

The shallow 6/32-inch tread depth and soft R-compound wear much faster than standard street tyres, so mixing them with older, deeper-tread rears will create uneven grip and handling imbalance.
