Just ordered a set of Sumitomo HTRs for the MR2 for $47 a pop. Not the greatest tires out there but when you're working with 14 inch wheels there's no actual summer tire option you've got to take what you can get. Plus, the Sumitomos are widely regarded as the best in terms of "performance" short of Direzzas or Azensis in the 14 inch range and as I'm not using the MR2 for autocross and driving it through rain and such there's no way to justify them.
