I'm thinking about getting some 18s or 19s, but i'm leaning towards the 19s. Wondering how bad it will mess with the speedometer, and if the computer be reprogrammed somewhere to recalibrate the speedometer to compensate for the rims?

yeah it fucks up the ready and it changes your lift point up to around 6,100RPM and it slows you down overall, i don't know the exact ratio of how much faster you are actually going but it isn't much say 100km/h is actually 103 to 107km/h
but they look fucken sweet!

Lift is not effected by the speed of the tires, lift will engage at the same RPM regardless of speed or gear you are in. The tires will however change the gearing ratio you have to the road, this will effect torque & the speed you go in & out of each gear. Putting larger than stock circumference tires on a car is a dumb move, especially on a 4 cylinder where your starving for torque to begin with. ![thumbsdown thumbsdown](https://celicahobby.com/forums/images/graemlins/celica/thumbsdown.gif)

Featured Articles >> [WHEELS] Tire Size / Speedometer Error Calculator This script is for comparing original equipment tire size to alternate after market tire sizes. The following is an example to help to decode a tire size like 185/65R14 185 = tire width in millimeters, measured from sidewall to sidewall 60 = sidewall ratio, the ratio of sidewall height to tire width 15 = wheel rim diameter in inches Wheel Speed Calibration script... https://celicahobby.com/tech/speedcalc.html

To calculate, there's also: http://www.miata.net/garage/tirecalc.htmlAnyways -- If you want your celica to look the dogs dangly bits, you go with 19's. They're hella-sweet, and fit the celica perfect. I'm totally lovin' my 19's! ![[Linked Image from img.photobucket.com]](http://img.photobucket.com/albums/v398/markryder/2510f526.jpg)

When I bought my 19's I did a little math to find out how far off the speedo was and it turned out to be almost nothing. using Distance ---------- = Rate Time
I came up w. a 2 mph difference at 35
and a 4mph difference at 65
So basically you have nothing to worry about
