Hi, I have rims with these dimensions:
19x8.5 45mm offset
19x9.5 45mm offset

what size wheel spacer would I need to make the wheel flush looking with the fender?
thanks!

 

Umm why would you get such high offset of wheel?? Well to get them to even fit you would probably need a 15mm all around. To make it flush it really depends on tire size but a 30mm or 35mm should maybe do the trick. I would sell those and get a set with a correct offset to fit your car.

 

I agree, you should get new wheels. Those offsets are way offset. Probably, as a rule of thumb, wheels shouldn't have greater than +30 (for example yours is 45). But, if you must, the below link may help in measuring.

The only thing is, it only goes to +25 (spacer size).

 

Do you have a ruler? Then measure how far you want to move the tires.

 

I would get wheel spacers that include new wheels. Sell your wheels to an S2K guy or something

 

they won't be flush with any spacer with that wheel offset. u would need at least a 40 mm spacer & i think 30 is the max they make. so yeah, u would need at least a 30 to bring u somewhat close.
