The stock tire size for my truck is 205/75/R14 I was wondering what all sizes I can get on the truck and still not have to recalibrate the speedometer? I am looking at taking it to the trails (nothing heavy) and would like a tire worthy of sustaining the terrain. Also, can I bump up a wheel size and still not have to recalibrate? Thanks in advance. It is a 1987 Mazda B2200 2.2 litre 4-cylinder SE-5 cab plus w/ Manual Transmission and 2-wheel drive.
