quick tyre question

[nathanVY]

hey everyone, just quick question about tyres.

getting 18s on monday, rear tyres need replacing. My car is currently chewing out front and rear tyres really quickly, the tyres on the front of the rims I'm getting are almost new, so I don't want to chew them out til I can afford to get the issue fixed.

looking at 6 secondhand tyres (really cheap), but they are 235/55/R18 - so higher profile, I know my speedo will be out but are these fine to fit to the car for the time being?

VS calais, lowered.
thoughts much appreciated, cheers.

Never mind, fairly certain the won't fit.
