Whats the factory tire size for 95 buik regal?

If you have 15" mags, you will need 15" tires.
The way tire sizes work is as follows:

• The first number (205) is the TREAD WIDTH in millimeters;
• The second number (70) is the percentage of the specified tread width the measurement between the tread and the wheel is (which means that the distance between the tread and the wheel is 143.5mm).
• The third number, 15, is the rim diameter in INCHES.

Do a little math and you can figure out the proper size tire for your vehicle with the after-market wheels you are using.

The bearing is pressed on the axle shaft. If you don't have access to a shop press, then let a mechanic do the job.

in the USA? (all countries, are different) over 50 markets.

The activation switch at the door is bad or stuck. Buy a new or used one or take it out n un plug it. Tape the end.

Pretty much all car speedometers built since the mid 1980's are electric. Do you mean that your vehicle is equipped with a DIGITAL speedometer?

If so, when you say it doesn't work, do you mean it does not light up at all? or do you mean that it lights up and just says "0" all the time?
