firstly, those profile's are too high, so im going to assume u mean 40 profiles and go on that.
on the rear, yes, as long as u have standard camber arms, it will be tight, i cant guarantee no scrapage as every car is different, and suspension plays a big role. if u want to go as wide as possible there is work to be done, 9" and 10" can be fit under unflared guards, with 235/40 and 255/40 quite easily.
front will be tight with the upper control arm, my guess is it will foul. once again every car is different, but if be going for a maximum of +30 offset.
what exactly are u after? as if ur just after looks, then u could save urself a lot of hassle by just going a smaller tyre, if ur after performance then ur going to have to look into camber arms and reduce ur camber, then we will be starting from scratch, there's no point running really wide tyres to get straight line traction if ur running a lot of camber.
