Will my speed be off once I put on the 18's?

[FreeStyler]

I just bought the bekkers reps so my classified ad is no longer needed, unfortunately im broke so i went with kumho's, but my real question is about my speed. Since my rims will be bigger, my speed on my dial wont be accurate anymore, how should i go about fixing that problem. Thanks. (i already have two tickets, so a faulty speed guage wont help this situation.)

your rims will be bigger.. but the overall diameter of the tires is still the same as or pretty close to stock.. so you will not have to worry about the speedo being out.
