I ended up with some used RA-1s of a size no longer legal for Pro-3. They were my rain tires back in 2007 but never used until I put them on my street car. There are no track heat cycles on them but many street miles. There is 2-3/32s on each tire. Manufacturered in the 46th week of 2005. $50 per tire OBO by Seattle race. Pick them up at my house in North Seattle or I can bring them to ORP or PR.
