1. Those tires are too large for your car. 215/45/17's are the stock tire size, and 215/50/17 are more than an acceptable percentage larger then stock.

2. Those tires are too narrow for the wheels you're trying to put them on. The widest wheel those tires are rated for is 7.5" wide.

 

thanks thats sad i just got them [tires] and i want some rep bbs rs rims and there the only ones i could find in 17s

 

well how would i put them on there and would there be any major problems or any extra ware ? just trying to get all the info i can

 

To run those wheels, you'll need the following:
1. Some negative camber.
2. Rolled fenders & quarter panels.
3. 225/45/17 or larger tires.

Can it be done? Yes.
Will it be easy? Nope.

 

well do u know of any more bbs rs reps that are made in 17" 7.5 ?

 

Privat Remember's will work for you're request.
17x8 +35

i have also been looking up some work emotions cr kai that are 17x7or 8 or 9 and + 47 or 42 or 32
im thinking 17x8 +32 but will my p215/50/r17s fit on them ?

 

Again, 215/50/17's are too large for the car. 215/45/17's will fit the 17x8's though, and could clear the fenders/quarter panels if you did some rolling work to them.
