Outer Limits 4x4 Board

my mates had his spare tyre off his 75 troopy at my place and he came to pick it up. we got talking about them and and as i was looking at his tyre i noticed it had a machine like cut right round on the inside wall that i new wasnt meant to be there. he told me it was off the front passenger side so i stuck my head under and sure enough that tyre had the same gouge in it.

with a bit of testing i noticed that when turned to full right hand lock the nipple on the tierod fitted perfectly in the cut. the whole drag like feels sloppy but i dont know why it would be hitting there.

hes running speedy rims with 285 75 16 bfg at's

any ideas please ?

Rubber flexes ...

Offset of the rim? With the extra width and height of the tyre, you need a bit more offset to get them out and away from the steering on lock.
Have a look at the steering stops and see if one side is adjusted more than the other (this could be why it hits only on one lock).

thanks guys, will have another look when im over his way soon. he wants to get new rims so may kill 2 birds with the 1 stone........
