Hi guys, can any of you give a view about my wheel alignment report please? I have quite bad wear on the inside of my front near side tyre. It must be an alignment issue but the report shows green zones in most places. Also, can one even adjust the camber on the rear axle?

Thank you.

I am happy to help you with all your questions. I am not a qualified mechanic but seem to be better at fixing my car than even the most experienced garages.

-1 camber will cause it to wear as they are heavy cars - in tollerance just means the manufacturer thinks its acceptable, the closer to zero the better but its not adjustable so unless you want to replace the leg it is what it is. Make sure you have decent tyres that are XL rated as the load rate is a good cause for wear, you can also offset tyre wear from camber to a small degree with tyre pressures. Mines run on 38 OSF and 35 NSF for about a decade now as the wear is near perfect then.

There is no adjustment on the rear unless you have the AWD variant.

Thank you. I pump mine up to 46psi all round but we usually have the car heavily loaded (bunch of fatties lol) and I've found that the tyres tend to wear on the edge before the centre so this seems to work ok. That's a very good tip however, I will put the front near side up to 48psi as that might help slow down the wear a bit.

Interestingly, it's the front near side tyre which wears on its inside edge. The alignment shows as being in the green zone but is right on the limit - do you think that would cause the wear? The last time I changed the tires, it was really very worn on the inside edge and there was still 4mm left elsewhere... Almost down to the metal braiding bit on the edge, which was quite terrifying.

I called "tyre pros" and they said they could change the camber on the rear axle, but I think they're talking out of their backside because it's not even adjustable, is that correct?

Thank you again for all the help with this

S-D-A - check the state of the rubber bushes in your front lower control arms (lower wishbones). The rear bush will get torn during visits to potholes, and the whole rear bush can move fore and aft, more likely aft, taking the control arm with it. To my way of thinking, that must then knock out alignment.   

What amazing expert advice, I will definitely do this - thank you!!
