In theory they should JUST clear the front struts, but.........
My 235/55 R17s have just enough room for me to run my finger between tyre and front strut / coil spring housing.
You are going to be 1/2 inch bigger and will be right on the limit - all things being equal, but.................
The size 235/55 is a nominal one and tyres my vary by as much as 4mm between brands and tread patterns - beware!
Also you must allow for the tyre to flex a bit under cornering forces.
Also your speedo will under-read by 3mph at 70mph.
Conclusion - this is risky - don't go there!
