can you lift the roof of the garage in it's entirety?

OK, I'm no structural engineer but... That steel angle is structural and will not only be holding up the roof but also tying together the top of the wall to stop it splaying out and supporting the front cladding. I would, therefore, be very reluctant to cut it, without some additional replacement bracing. Presumably, the garage has a similar truss or two along the length of the garage which will be at the same height so would need to cut them all, risky!
As suggested above can you lift the whole roof by inserting either brick or 6x3" timber rail? But again make sure you brace this well back to the wall below. You could cut the brace if you welded in an additional RSA a little higher and brace back to all the other trusses. Not a big job if you know someone handy with a welder. But I suspect just raising the whole roof might be easier?? I'd guess digging up the floor and lowering would be cost prohibitive and potentially cause drainage issues. What about air suspension and self-inflating tyres to lower in and out  James

I wouldn't be grinding off anything of the part you've shown. The vertical bit of the angle is what gives it its' strength.
To be honest, I'd fit the new tyres and measure the actual height before doing anything. On paper, they should add about 40mm to the overall height but the real world often doesn't work quite like that. If it is too tall then, as xcentric suggests, look at raising the roof structure and adding in a timber plate on top of the concrete walls. With a bit of ingenuity, raising the roof could be done without dismantling it. Beware the roof sheets though as they look very much like asbestos cement which needs special precautions if you're going to disturb it. It really depends on how much money you want to throw at it but a better overall solution would be to remove and dispose of the existing sheeting, lift up the structure and then reclad with something modern.

Obviously first plan is fit wheels see if actually fits... if not then scratch head...
Good suggestion about raising the roof on wooden blocks.. I'm not planning on spending much at all on this garage as if I am to spend it will be on a wider / higher wooden new one... But I didn't want to have to do that just yet. The bit in my picture I was going to grind is hard to show it does not look like that parts itself is part of the bracing? the bit between 200cm and 204cm. Also I could leave at least a foot each side before I ct a piece out... Think I will ask me dad he's always good at these types of things 
I could of course keep the small wheels on... but I don't want to |

I've got a similar problem to you - my Ninety just about fitted fine on 600's, but the want for 750's was too strong to resist
My garage is an internal house one so my solution is to replace the up & over door with a side opener or roller, neither of which helps you, but I discovered two things during my very careful measuring sessions: 1) My real height increase when fitting the 750's was bang on 50mm. 2) If the drive is lower than the garage floor, the highest point on the car will temporarily be even taller as it drive in or out - I did a CAD model and it was about 8mm which made a difference believe it or not!

5cm increase will be very tight...... I can live with tight as long as it goes in.
However like you there is a small ramp into the garage... |

First job would be to get it on the 750's and measure it, but for exacting purposes you need to factor in the weight of the driver as it makes a difference. As does whether the fuel tank is full or not...
I measured with a near empty tank as don't want to store excessive flammable fluid in the house. Perhaps you could be disciplined enough to brim the tank every time you park it up? Every little helps Instagram: l90andy

Reduce your tyre pressure?
I had a friend who when he retired, did a little maintenance on cars as a side line to help bolster his pension. He got the job to rebuild an engine in a Renault Master. His garage door was just too low to get the van in so he reduced the tyre pressures and he just about squeezed the van in. He was an 'old school' engineer. I'm not sure if this would help you as I presume you are looking for a permanent fix? One thing to watch if you are playing around with your roof. That looks like concrete asbestos and although it is pretty stable, you wouldn't want to go breaking any of the sheets. |

Or just let your rear tyres down to get it in and out
not ideal but would work in the short term |

What you've got to remember is that structures like this were built to be as cheap as possible and so there is very little 'extra' material. Hack them about at your peril.
