Hey all I chickened out on the auto tranny to manual swap I think I will do it in the next off season. So I bought A brand new set of 255/60/15. I bought a 235/60/15 for the left rear is that the correct way to get stagger cause that gives me close to 2 inches? Should that be enough on half mile dirt. Also I no you cant go wrong with new tires but I went from a 205/75/15 6 inche tread tire to the max 8 inche tread and I never had new tires will I feel a difference or just have good rubber?

car should handle better with the wider tires as for your stagger thats one way to get it air pressure is another. if it's a metric car i would go much more than that and take some out on realy dryslick

The first number is the width of tread in millimeters, and the second is the height of sidewall in percentage in relationship to the width.
a 60 series is 60% of the 255 so the sidewall height would be 153 millimeters.

the first number(265) is the section width(not neccesarily tread width) in millimeters. Divide by 25.4 to get inches.

the second number(60) is the aspect ratio or percentage of section width that equals the sidewall height. ex. 265 x 0.60=159mm divide by 25.4=6.26". This is the sidewall height.

The last number is rim diameter.

To get the tire rollout add (rim diameter+section height+section height)x3.14 = 84.8"

If you wanted a shorter left rear tire you could also go to a 255/55/15 which would give you the same section(and tread)width but shorter overall tire, equal to your 235/60.

or run a tape messure around the thing and get the roll out thats the only true way to figure out roll i've seen two brand new tires same size from different manufacturers be 2 inches different roll wise right off the shelf the size rim you use will play a part in it to. i go by this simple rule 255 is how tall 60 is how wide so a 205/75/15 is gonna be taller then a 205/70/15

Section width is the measurement bead to bead.
