Chris2012 Posted July 18, 2013 Report Posted July 18, 2013 To what extent is this possible? 1992 Lumina 3.1 takes p195/75r14's. Pepboys has a list of acceptable near sizes. This was all news to me until recently. Quote
WhatTheFehl Posted July 18, 2013 Report Posted July 18, 2013 Within 3% overall diameter is generally what is considered "acceptable". Quote
MonzaRacer Posted July 20, 2013 Report Posted July 20, 2013 195/75/14 changes over too 205/70/14. NOW as long as you keep tire diameters identical you can change tire sizes, keep the same diameters you can switch too 15s,16s,17s,18s. Like my 98 Regal has 215/70/15 which means I can run 225/55/17 check here:http://www.rimsntires.com/tireplussizing.jsp?sectionwidth=215&aspectratio=70&biddiameter=15 Quote
