Harold M Posted January 7, 2012 Report Posted January 7, 2012 On 47 Ply. how much, in inchs, should the top of the tire lean in or out thanks Quote
james curl Posted January 7, 2012 Report Posted January 7, 2012 On a 26.22 inch Diameter tire, the maxim camber is 3/4 of a degree. The most that the tire can be out of plumb would be .343 of an inch. Between 5/16 and 3/8 of an inch. Take a 24' level and place a 26 1/2 inch 1"x4" board between the tire edge and the level, then plumb the level. Measure to the same spot on the side wall that corresponds to the location on the bottom where the board contacts the sidewall, now measure to the corresponding spot on the top side of the sidewall, it should be less than 5/16".

busycoupe Posted January 7, 2012 Report Posted January 7, 2012 James, your method for checking the camber seems like it would be difficult to use. The tire sidewalk bulges out on he bottom side of the tire, more so with radials but some still a noticeable amount on a bias ply tire. Perhaps with a little calculation your method would work with the top and bottom edges of the rim. Dave Quote
Niel Hoback Posted January 7, 2012 Report Posted January 7, 2012 Thats how I checked mine. Drive two nails into a 1X2 with about an inch sticking out. Make certain both nail heads are the exact same height. Use this against the wheel edges with the level to check the angle. Quote
Harold M Posted January 7, 2012 Author Report Posted January 7, 2012 I have clamped two wood blocks to a 18 inch level so they just hit the rim but I didnot know which way to lean it or how much thanks alot Quote
james curl Posted January 8, 2012 Report Posted January 8, 2012 the manual does not specify negative or positive camber just 3/4 of a degree as maximum amount. On a 15" wheel that would be a maximum distance at the top of the wheel of .196" or just a little more than 3/16" in or out at the top of the wheel. Quote
james curl Posted January 8, 2012 Report Posted January 8, 2012 If you have positive camber then the tire leans out at the top, away from the car. Negative camber the top leans into the car. The manual just calls for a maximum of 3/4 degree, does not specify either way. Quote
Alshere59 Posted January 8, 2012 Report Posted January 8, 2012 (edited) Why not just get an inexpensive magnetic gauge and measure the spindle? Granted it would need to set at roughly the ride height with the drums removed and on jack stands. If you have disc brakes it is very easy, you can just place the gauge on the rotor. I have disc on the front and it worked for me when I did my front end rebuild. It just went up for a quick check by the alignment shop and I went on my way. This article gives the why I think neg camber is the way to go. http://www.familycar.com/Alignment.htm Edited January 8, 2012 by Alshere59 Quote
