Im on ebay looking for rims and I came across a good deal for 18" chrome cobra rims. I know i have 16s on right now. Am I able to put 18's on with no problem or will I run into problems?

 

You'll be just fine, you'll just have to use low profile tires.

 

Going from 16 to 18 wont change the gas mileage or turning radius?

 

not turning radius...and BARELY gas mileage. depends on how heavy they are. but i doubt ull notice

 

+1 35 series

 

Gas mileage should be insignificnt but your mph guage will be alittle off. 1 spin of a 16" covers less distance of a 18", so itll say your going slower than what you really are (not much of a difference though).

 

dude wont the overall diameter of his tires stay the same? because yes the rim is gettin bigger but the tire sidewall is gettin smaller to compensate so he will b fine with the speedo

 

you can put 20" spinners on if you want to!!! j/k!!! they will fit

Not necessarily. Most of the time its bigger than stock. You can always get your speedo calibrated for like $60 though, so its no problem. Use this link to find out what rim and tire zise will not require a speedo calibration.

 

the smaller side wall should compensate for most of the bigger rim. I went from 15 to 17 and my spedo changed none. The most urs should change would be 1 to 1.5 mph. not really worth 60 bux. just get what u want remember about the speedo til u can get a tuner. Really no change that u will be able to tell exept way better looks.
