Currently have 555 on the front & 555R on the back. Intend to do more Auto-X this year & would like to try the 555R on the front.

Car goes out every day it not raining & the temperature is over 45*F. have not had any issues with the rear tires in DD.

255X40X17 555 - 315x35X17 555R. Have a set of unused 245X40X17 555R sitting in the garage getting old.
