Hoosier Launches the TrackAttack Race A8 and R8, Replacing the A7 and R7

Hoosier replaces the A7 and R7 with the TrackAttack Race

Hoosier unveiled the TrackAttack Race at the PRI Show in Indianapolis on 12 December 2025. It is sold in two compounds, the A8 and the R8, which take over from the A7 and R7 that have been the company's DOT competition radials for around a decade. The new tyre carries a 040 UTQG rating, and while it is DOT approved Hoosier does not recommend it for highway use.

Positioning

The TrackAttack Race is the second product in Hoosier's TrackAttack line, following the TrackAttack Pro of September 2024. The two are not interchangeable. The Pro is rated 200 UTQG and is recommended for road as well as track use; the Race is rated 040 and is built for dedicated track environments only.

Joerg Burfien, Hoosier's president and chief executive, presented the launch as a naming change as much as a product one, saying the company had historically named products after compounds or internal codes in a way customers found hard to navigate. "Our new family naming makes it easier to understand each product's core purpose," he said, adding that Hoosier expects the TrackAttack family to grow under the same name.

The two compounds

• The A8 is the medium compound. Hoosier describes it as providing "ultimate race traction and performance", which places it in the A7's role: autocross and short sprint work, where peak grip counts for more than how long that grip lasts.
• The R8 is the harder and more heat tolerant of the two. Hoosier says it offers consistency and durability, the R7's role: circuit sessions long enough that holding a lap time matters more than setting one.

Hoosier refers to the underlying technology as H-DNA, but has not published the compound or construction detail behind the name, so what has actually changed against the previous generation is not public.

Manufacturer performance claims

Hoosier says the TrackAttack Race is engineered for faster lap times than the A7 and R7, with "unmatched consistency with minimal fall-off" and what it calls instant responsiveness and planted stability. Those are the manufacturer's own claims, and no supporting figures were released with them: no lap time deltas, no venue, no reference car, no comparison set. Mike Edmiston, Hoosier's head of R&D, described the tyre as the product of "years of focused refinement and real-world testing" without attaching numbers to it.

For independent context on the generation being replaced, our own Hoosier TrackAttack Pro vs R7 vs Slick test from 2024 measured the R7 against both the street legal TrackAttack Pro and a Hoosier medium slick. Neither the A8 nor the R8 has been through an independent test on this site.

Sizes and availability

• 51 sizes, covering 13 to 21 inch rim diameters.
• The range runs from 195/60ZR13 at one end to 345/30ZR19 and 335/25ZR20 at the other, with both compounds offered across it.
• Hoosier said at launch that selected sizes were already with distributors, with the remainder to follow.
• A7 and R7 supply is winding down as the changeover proceeds.

What it means for drivers

The A7 and R7 ran for around a decade, so replacing both at once is a real change for anyone buying DOT competition tyres, and the 040 UTQG rating makes clear these are not a tyre to drive to the circuit on. What the launch does not settle is the part that matters: whether the A8 and R8 are genuinely quicker over a lap than what they replace, and how well they hold that pace once heat is in them. Hoosier claims both. Both are measurable, and neither has been measured in public. We will report on how the claims hold up once we have tyres to test.
