Hiya, as my avater says, i am a noob to this forum and wasnt quite sure where to post my question. Basically im after getting a set of 16 inch wheels for my EK civic.
Question being. Will the larger 16 inch rim size, throw out my speedo reading? I am currently running 15's with 65 profile tyres.

Thanks.

 

Your speedometer will not be thrown off if you put the right size tire on it. I believe the correct size for 97+ civics is 195/55-16. I'll nsxtasy chime in here.

The change in the speedometer reading depends on the tire size, not the rim size. The general objective in choosing a tire size is to keep the outer diameter as close to stock as possible, which also minimizes the change in the speedometer and odometer readings.

The '97-00 Civic in the States comes with 185/65-14 or 195/55-15 tires (which have the same diameter); with 16" wheels, either 205/45-16 or 215/45-16 both work.

However, I think the cars sold in the UK came from the factory with different size tires from ours, so it's possible those sizes might not be best for your car. What is your stock size (e.g. 185/65-15, 195/65-15, etc)?

When changing sizes, you can look up the percentage difference in diameter using a tire size calculator like this one.

This should be written on a sticker on your door jam or can be found in your owner's manual if you don't know where to look.

 

Hiya, thanks for the replies. The size is 185/65/r15. The reason behind the 16's is i want to fill out the arches a bit more. I know that a 15 inch rim would give the best ability, but as its my daily driver and i wont be getting springs for her for a while, i didnt want to put 15s with 50 profile tyres on the car as it would look a bit out of proportion.

Once again thanks for the help

That size is the same as the later (e.g. 2002) Civic EX here in the States.

The Tire Rack recommends size 215/50-16 for 16" wheels on that car. 215/50-16 has exactly the same outer diameter as stock (the difference is less than 0.01 inch) so it would not change the speedometer reading at all.

There are not a lot of tires available in 215/50-16, but there are a few, including some good ones. Good choices for summer tires (if you never drive your car in snow or extreme cold) include the Avon Tech M500 and Dunlop Direzza DZ101. If you need to drive your car in winter conditions as well as the rest of the year, the all-season Kumho Ecsta ASX is available in that size as well.

 

Thanks for the info nsxtasy. I will probably run the steel wheels through winter as it gets pretty salty where i am. If i do get a set of tyres for her, at least i am now safe knowing that the 50 profile choice is the right one and wont affect the speedo rating, as where i live, we have a thing called the speed camera Anyways, thanks once again. I will probably stretch some 195's on the tyre as the width is 7.5

Most 195 treadwidth tires are not approved for mounting on wheels 7.5 inches wide.

Most 215/50-16 tires are approved for mounting on rims 6.0-7.5 inches wide.

 

your car will feel alot heavier though...i've gone from 15's to 16's and man my ej8 felt so heavy...went back to 15's...
