On a 360 Modena, the rear tyres are wearing more on the inner-edge area of the tyre surface than the outer edge. This may or may not be due to the suspension system on the vehicle )- on a 'normal' car this would indicate a need for a wheel alignment.

The car is due new rear tyres but I'd rather take the wheels off and just take the wheels in to have new tyres put on, rather than leave the car there. However, if this indicates it needs a wheel realignment, I may not have that choice.

Does anyone know if this wear pattern is normal?

Its part of a service to do a wheel alignment.

Check your hanbook, it says "check car geometry".

Just have the car serviced properly, and worry not!

I'm gunna throw a wild assumption out there and guess whoever services it doesn't do the full lust of requirements though, so in that case, YES, it needs checking. But the wear depends on how you drive.

If you're a straight line squirter, it'll wear inside edges prematurely, but if you drive sportily, it'll wear more evenly.

Just get a specialist to do an alignment. The rear floor needs to come off and it can take 2 hours, but "I" do tyres and alignment "while you watch and wait", perhaps others do too?

Am I also correct in saying that it has to do with the engine mounts also FF??
If they are worn, do the tyres wear more on the inner edge?? Or is it purely a shimm/alignment issue?
Everything looks better in carbon fibre

Thanks FF, - sounds like it's a job for Automotion, though I am a bit of a straigh line squiter.

dreamin!

Engine mounts bear no relation to tyre wear.

The car has camber as standard, if you drive it without leaning the chassis in a bend, you'll wear your tyres earlier than need be.

360 suffer from rear toe link inner mounts failing also, so check those. also lower ball joints are weak, uppers not much better.

Chris and the boys at Automotion will make it right. Say hi from me ;)

Hey FF.... is this because if you gun it off the line (and straight) being an independent rear it squats and therefore increases the negative camber - and the friction is greatest on the inside edge? Thus more wear on the inside edge.
But the problem of being a "sporty"driver in a Ferrari is the Police who may take the view that your sporty driving is dangerous driving.

Excessive squatting could be rear springs and/or shockers and/or rear bars getting tired? Yes/no?

Is there the ability to dial out a bit of the negative without rooting the charastics of the car?

When you say take out rear floor..... what are you meaning?
