i need some advice guys.. right now my tires are set up to 225/45/17 on the front and 215/40/17 on the back. the back tires are brand new and previously had 235/45/17 dont ask why cause i got them for uber CHEAP! and handling was amazing with almost no body rolling but it feels like my car was "dragging" (engine revving harder) too much when accelerating. with the smaller tires in the back i am able to accelerate alot better overall and alittle more oversteering so maybe just alittle body roll included compare to the wides on the back.

so the question is im gonna need to change the fronts real soon and i was wondering if i should go size 225/40s or 215/40s or what do you think? i want set up for better acceleration, gas mileage, and handling. mind you idc about tire rotations
