" From: "John W Rosa" <JohnRosa@xxxxxxxxxxxxxx> " " " My Hornet's original tire size is D70-14, " which roughly equals (correct me if I'm " wrong) P195/70-R14. " " Now my understanding is 195 is millimeters " of tread width, while 70 means 70% of the " treadwidth is the sidewall height, and 14 " is naturally the wheel diamter in inches. " " I'm looking to find out what is the near- " equal size in width and height for a 15" " tire. Is P195/60-R15 the closest? And is " 225/60-R15 too wide/tall for a stock Spirit " suspension to handle? going by with others said, that 205/70r14 is the direct match -- # tire 205/70r14 215/60r15 235/55r15 255/50r15 Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 205/70-14 5.6in 12.6in 25.3in 79.5in 797 0.0% 215/60-15 5.1in 12.6in 25.2in 79.0in 802 -0.6% 235/55-15 5.1in 12.6in 25.2in 79.1in 801 -0.5% 265/50-15 5.2in 12.7in 25.4in 79.9in 793 0.5% i wish i could recall where i found 'tire'; it was on the pre-web internet -many- [15?] years ago. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
