  • 18 inch rims triggering traction control

    I got some 18 inch C5 rims in the back and 17s in the front. I programed my PCM for the new height with the 275 tires, but when i go over like 80 the low traction light comes on and the throttle is cut, it drives me nuts. What can I do to fix it (besides turn ASR off)??

    Thanks

    I GUESS at high speeds the car is thinking the front wheels are moving faster then the rear. Being the front is 17 and rear is 18.

        Can anyone help me? When I hit the brakes it triggers ABS as well. Please respond.. No one ever does.

            There rigth . your eithe rgoing to need to buy 18 for the front or figure out a tire size thats about the same as the rear . and i dont think you can flash the abs computer with diffrent tire sizes . it allways thinks its loosing traction

              true, you can only flash it for one size, not two, your best bet would be to buy 18s for the front.

                What size are your rear tires? Use this link to help get your tire sizes for the front and rear to share the same ratio. http://www.miata.net/garage/tirecalc.html
                Like a 235/55/16 and a 275/40/17 share almost the same ratio. That should help you out some, but you can prolly get a closer tire size than that.
