i have heard that if u get larger rims on a civic that u have to like recaliberate the speedometer. beacuse the tires are bigger the speedometer would be slightly off. is this true. also what are the largest size tires i can put on and still be able to turn in every day driving?

when you get larger rims... you get lower profile tires to keep the outer diameter the same. If the outer diameters are the same... you shouldnt have to worry about the speedometer.

Just make sure you get the right size tires to keep the overall width of tire+wheel the same. If you don't then you will need to get it recalibrated. If you want help figuring that out check out this web site. http://www.miata.net/garage/tirecalc.html

205 = the width of the tire in mm
40 = the thickness of the sidewall in mm
(I believe that is correct w/ mm)
...and if I can remember correctly 205/40/17 come out to an almost exact diameter as the stock wheels!
I imagine 215/35/18 would be almost perfect too!

The second number is the 'aspect ratio.' The height of the sidewall is x% of the width.. For example.. 205/40R17.. The height of the sidewall (thickness) is 40% of 205, which equals 82mm in thickness for the sidewall..LX98Civic said:
