Help choosing Hoosier tires for Formula Student

Hello everyone, We’re finalizing the reference for our 13-inch tires and found several options on the official Hoosier website. Here are the ones we’re considering (20.5x7.0-13 and 20.0x7.5-13).

Which one would you recommend for a Formula Student car? Also, do you know if there are other suppliers or distributors that sell Hoosier tires at a lower price?

Thanks in advance
