In short, lowered = extreme inner edge tyre wear. It's as simple as that.
Also, lower profile tyres = inner edge tyre wear.
You can claim some back by using the adjustable bushes - I have some fitted to the Holden, BUT these are only suitable for the outer position. The inner position relies on the bush being quite floppy for the suspension to work. Remove this and you'll get some very interesting handling traits as the wheel won't be able to move through its full arc properly. This is different to the Pedders information ( Omega B is subtly different to Holden at the rear )
unsure how low my car is..
its loaded atmo so i will brave the -3 outside
& measure from arch to wheel center front/rear & maybe some one could work it out??
right im back... front is 330mm rear is 310mm
the pair of rear conti 275 30 19s lasted 500miles before the inside edges egged to hell 10 in fact on 1 wheel!!
i tried a pair of nankang 245 40 19s like new with 7mm they lasted about 2000miles but rear toe was way off!! 2 replacement tierods & all adjusted up perfect!!
been better with the 255 35 19s the last pair of Pzero rossos did 1600miles but only had 4mm tread
the dunlops ive fitted atmo have done 1800miles so far but did have 7mm tread when fitted & down to 4mm on inside edge atmo but mostly motorway use last month,
