Easiest way is to reduce the profile of the tyres so that you wind up with the same circumference measurement. Otherwise you may be able to get different speedo drive gears in the transmission.

    i sorry can explaine that in some more detial on the part about the profile part?

  • Bill Boyd Apr 20, 2013

    Tyres come in different profiles Ie 195/95 r16---195/55 r16 and 195/25 r16 If you have a look at the side walls of the tyres you will see that the 95 profile puts the rim well clear of the road the next closer to the road and the last looks as if you have no tyres on the rims. So if you had standard 16 in rims and 95 profile ( standart speedo ratio gears) and you fitted 17' rims with 95 profile tyres then you will be going extra distance for every revolution on the wheel.By reducing the profile to the lowest distance then the circumference of the tyre means that you will be moving approx the same distance per revolution. If you are still a bit baffled have a chat with your tyure dealer and he will explain by showing what I mean on the side of the tyres.

    ford sorry it 530 am no sleep hehe

    I have done some rough calculations. 16 "wheels (no rubber) will cover approx 4188ft per 1000 revolutions while 17" wheels (no rubber) will cover approx 4449 ft giving you a distance of 300ft further travelled. By using the c=3.141 x dia of the overall dia of the wheels you can work out how small the dia of the 17" wheels will have to be to come close to the same max dia of the 16' wheels to cover the same distance.

pull the instrument cluster out and check the printed circuit and connector to it from harness, plug it in and out three or four times, this may cure the problem.

Went up in tire size now speedo is off


You can go to Ford give them your vin# and tire size and a mechanic should be able to figure out what pick up,sensor or gear you need to make it accuracte. The easy and quick way is to buy a GPS unit and it reads your true speed.That is how we use to check speedo calibration. Mount the GPS and use it for the speedo. Most Fords are about 3 MPH off from the factory anyway.

What tires can fit a 1999 ford expedition xlt


I believe it will fit. If you go to DiscountTires.com you can use their site for alternate tire sizes. Especially handy is the feature which shows you the Speedometer error for different size tires. The site will also show you recommended and popular substitute tire and wheel sizes.

The 1999 model had a 265/65/17 as an alternative. You may want to ask the Tire store you intend to use if they can reconfigure your Speedo to be accurate. Some of the Fords can be done electrically without changing Speedo gears.

I did something similar by going from a "60" series to a "65" series in the same width. On my Grand Marquis, I gained 5% mileage improvement, but have to watch Speedo until I get it reconfigured. I hope this helps to answer your questions.

OIL FILTER BLEW OFF OR MUSHROMED OUT


Replace the oil filter, fill crankcase with proper amount of oil, drive car away and pray to God it was just a defective oil filter.

How "old" was this oil filter and how long ago was it supposedly replaced? Does the SVT have an oil pressure gauge (I know my non-SVT contour does not) and did you notice anything on the gauge (super-high pressure) before the filter burst?

Unfortunately, the idiot light tells you there is "NO" oil pressure, which is the condition you encountered after the filter went south.
