I need some opinions are 18 inch rims to much for a cruze? Or should I stick with 16 inch rims? Also if I do decide on 18's will I have to do any modifications to the car?

I thought the RS and LTZ packages were 18" stock. So, you should be A-OK with 18s.

Make sure they are 5x105 bolt pattern and you should be good. I am not sure about Offset however, maybe somebody else can chime in on that.

40-42 offset.
This. They'll be fine, I went from 15 to 18 on a lowered cobalt and never rubbed. I wouldn't go more than a 8-8.5 width wheel tho. And definitely make sure it's the correct bolt pattern.

Black is awesome with blue. I also own a Honda civic and it's blue is pretty similar to the cruze blue. I have Honda HFP gunmetal rims on it and I think it looks great. Have a look see:



Lots of work done to that car by me. Head gasket, 5 lug conversion, rear disc conversion, lots of other stuff. I plan to not touch the cruze forever. Look into the gunmetal though, I think it looks awesome with the blue.

one big factor of plus sizing in weight. Keep in mind that unsprung weight has a disproportionantly larger effect than adding weight to the sprung wieght of the body. Another effect is the overall diameter of the wheel and tire package. Going with a larger overall diameter will increase your gearing which can lower your rpms at higher speeds but will also cause your engine to need to work harder to get up to speed. Conversely if you go with a smaller overall diameter then you will shorten your final drive ratio, which will make gearing shorter but can cause your fuel economy to drop due to holding higher revs. If you are going to 18s then i would factor in wheel weight and try to find a wheel that balances looks and low weight. tires also affect your unsprung weight so look at the differences between tire size. Honestly on a car this size a 225 or 235 is more than sufficient for anything on the street. Ive seen LNF and LSJ guys running 245 or 255 series tires to get a wider section width for less wheel spin, but our cars dont approach the levels of power those put out. Either way good luck on your search. Keep us updated

Along with the weight piece is the wheel studs themselves. I would recommend upgrading them if you're going with a cheaper/heavier 18. I've sheared them before due to the stud not being able to handle the additional weight.

I was gonna go on an unsprung weight and increased stopping distance rant but figured someone would chime in with a cleaner packaged reply. Heavier wheels also effect steering wheel feel as well as wear & tear. Those one handed low speed turns are a bitch if the wheels are extremely heavy. Ask those who went from 16's to 22's on other cars how it feels to turn and replace power steering pumps. Speaking of, has anyone killed the power steering motor yet?

I'll let him answer regarding his, but with mine when I fully turned right to back into a parking spot earlier I got a little scrape noise. I believe at full turn 18s will get a little rub on either tire.
