when i change the wheels and tires to say 15 or 16, will my speed sensor remain the same or will it mess up the reading? i know, the question may be hard to read, but i think you know what i mean...i hope

 

as long as you use the right size tire it will read just fine

or if youre lazy
195/50/15
205/45/16

 

Actually the correct Civic tire sizes are:

185/65x14"
195/55x15"
205/45x16"

 

Or a 205/50/15 will work too. They are easier to find and a little less expensive.

 

ACTUALLY
205/40/16

i was giving sizes that are common and work well

 

thats what i have on mine:thumbup:

 

going to 205/45/16 tires from whatever i had took my speedo from showing 125 to my actual speed at 127.8

 

205/60/15

i know my speedometer is off by 5mph at 60mph

i'm gonna have to drop back down to 195/50/15's when i drop my car

i love my fatass tires

 

im looking at 205/45/16. they will work fine, right

 

I have 205/40/17 and it says my speedo should be off .1% but its def off by more....unless those things coppers set up on the side of the road to say "Your speed is" are off cause this summer I did like "40" by one according to my speedo, but that thing said 37 Oh and my car only had 35k or so on it at the time, so I dont think the speedo would be off yet
