Critical Tire/Wheel Measurements
for rear tire fitment on 1983-88 Monte Carlo SS

Please note!  The fitment data listed below is based on the current tire/wheel combination on my vehicle which includes BFG P275/40xZR17 tires mounted on 17" x 8.5" wheels.  The wheels are manufactured with a +15mm offset.  In order to fit this tire and wheel combination correctly, it required the use of a (19mm) 3/4" forged (6061-T6 plate) aluminum wheel adapter from Vette Brakes & Products, located in Saint Petersburg, Florida.  This gave me the -4mm necessary overall offset to fit properly.  If you would like additional information on how these adapters are used or what they look like please follow this link.
