Make sure you run any changes with your insurance company.
If it isn't listed then you run the risk of them refusing you cover after you have an accident.

I got t-boned by a car coming through a stop sign once and the repairers told me that the insurance would have been refused if I was at fault because I was due for we tyres.
I had only the day before rang around for new ones, but the insurance company would not have cared about that.
