TR2/3/3A Extreme tire wear

[TRclassic3]

Need some suggestions here. Experience rather extreme tire wear on the inside of the right side front tire. What's the most likely cause? Alignment? Something bent causing camber issue? I had replaced bushes a few years ago with delrin/poly. Heard of a possibility that they will become oval with wear. Anyone else experience this?

If it is only right front, then camber is where I would look first. I've learned from experience that some alignment shops will not actually check it, even if you ask them to (and they say they will). From their point of view, if it "can't be adjusted" then it must be right. If you have a reasonably flat floor to work from, you can make your own camber gauge from a carpenter's square plus a couple of small C-clamps and 6" rulers. Hold the square with one leg on the floor and the other leg vertical, then clamp the rules in place so they are horizontal and touch the wheel rim just inside of the outermost edge. For a 15" wheel, each 1/4" measured is almost exactly 1 degree of camber.

I'd also consider looking for torn/broken lower wishbone mounts and similar (hopefully obvious) problems.

The setup the fella made on Piston Heads is a very unique and cheap way of checking camber on pretty much any vehicle. An attached dial micrometer on the thread end of one of the bolts would even give a tighter reading once set up from level. This should be done only with all the weight on the wheels, not jacked up.

Also, no one mentioned, they are assuming that the floor is level. Many garage floors have a slight slope to them (mine does), which will affect the results when using a level or plumb bob. My method only assumes the floor is flat (which can also be a problem, but usually less of one).

I agree Randall, a level surface is surely needed using this method. PJ
