Sizes are the same, both 15” and 60 profile so there shouldn’t be any speedometer issues. What you need to do is check whether your wheels are capable of taking wider tyres so they sit correctly when fitted. Also check how much leeway you have for tyres sticking out past the wheelarch. I'll try and dig out a site that works it out for wheel/tyre size allowance.
Just did a google check and general info says up to 20mm wider is usually ok and adds about 5mm to how much the tyre sticks out. So, for a 6.5” rim 195 to 205 looks ok.
My plus 8 has standard Morgan alloy rims. 15x6.5xJ with 0.307 inset. It has 205x60x15 tyres.
