hi everyone ,i know this question has prob been asked a million times but i read many threads and iam still confused, please help. car is 93 wrx and its time for new tyres, when i got the car 205/40/17 tyres were fitted ,the car is on standerd suspension and is staying that way,but i have huge gaps betwwen the arches <wrong tyre size>. so my question is what tyres do i go for 215/45/17 or 215/40/17 . thanks in advance kev.

 

215/40x17" is the right size
