Tyre To Wheel Size

[ReaperGFX]

ive just got myself a new set of wheels for my celica, i didnt buy tyres since ive recently had Pirelli p-zeros fitted, the wheels are 17x7.5 and the tyres are at 205/45/17

have a made a mistake and should of got 215's or will i be ok on 205's

205/45x17's will be perfectly fine, but the next time you are ready to replace your tyres you could (if you want to) go for the 215's, you don't need to fit all 4 to change sizes, it's perfectly legal to do it in pairs, but you would neet to fit the larger tyres to the rear even if it means swapping things about.
