I purchased a set of R888 (195 for the front and 235 40R 17 for the rear) from Tire Shoppe and have been running them for a week now. So far, I am very impressed with their wet weather performance and they stick so much better than my warn out AO48s in the dry. I do find that they feel less precise than the AO48. I have not yet played around with tire pressures to see what suites these tires best. Anyone have any experience with street and track pressures for these tires?
