My setup has been on the road for 4 years now.I just over the winter switched from a 6" wide radial tire wheel combo to a 40 style 16" wheel with a 4"wide front a 4.5" wide rear.I just noticed the fronts are wearing with a taper.I went back and checked the radials and they show signs of the same wear but not nearly as definitive due to the width of the tire.I went back through and made sure the toe in was at 1/16 to 1/8" in so standing back looking to front there is a definite positive camber on the wheel.Front setup is Pete and Jakes super bell axel with round spindles and hairpins.Just wondering if I may be missing something or it is possible that there is just that much camber built in.I am currently leveling the car to I can get a exact degree but came in for a break real quick to regroup.-Drew
Ok, a couple of things here. What kind of negative or postive offset do the front wheels have? What is the camber now............should be around 5/8 positive. Usually, wearing the outside or inside of the tire is because of camber, not toe in or toe out. Also, just for fun..................take the center line of the king pin straight down to the ground and it should intersect with the center of the tire...... called Scrub Radius..........and let us know what you find.
I belive that my Super bell 5'' drop has a 1+ degree camber already set in the axle. You can of course take it to an alignment shop that use to do the old Ford twin I beams , and have them bend the camber to your specs.
I have included some pics to show wear and take some additional measurements.It appears that the stock 40 style 4" wheel has around 3" offset.The closest I can gather on my scrub radius is zero,Both lines intersect at tire to ground level if not king pin angle being a little outside the centerline of the tire.
OK, good picture of the tire. It looks like what is called "Feathering" which is normally caused by toe in or toe out. Can you give us some very specific information on the car; What car is it What kind of axle, tube or I beam and how old is it What kind of steering and how old is it Are the spindles new or how old Are the drag link/tie rods new or older Why are you setting the toe at 1/16 low and 1/8 high Just off hand, if the steering box is brand new....not rebuilt then I guess I would agree with the toe setting If however the box is used and has some miles on it I would say 1/32 low to 1/16 high How doe the car handle on a straight and level road........how about a straight road with a crown.
Toe in wear. That looks like a toe in problem to me and not a camber problem. We call that scuffing around here. The tire is actually sliding sideways going down the road. This is a camber problem.
