Good one. The rubbing is in the front part of the liner when turning. Hmmm .... so I will have look into those adjustable tension rods I suppose. Is this what those people who have bigger tyers mounted use to get rid of the rubbing? It is never mentioned in those posts and I did some serious searching on the subject.
:If they are rubbing the front or rear part of the liner when turning, changing the caster setting may correct it. Not much you can do if they are rubbing the top part of the liner. My 275/40/17 fronts are really close in height, they are just touching the rear liner enough to polish a small spot at lock. You will need adjustable tension rods to adjust the caster setting.
