New tyres on a 1275 with 5j 13 alloys

[MOM]

Hi.
Time for new wheels & tyres.
New wheels on way & am looking at 155/80/13 tyres.
Does anyone have any recent experience.
Do not want to over stick the car but good wet weather breaking a bonus.
Any input much appreciated.
Regards.
Mark

Now finding a delay on the 80 profile would 70 make that much difference e.g. filling of the wheel arch & gearing ?
