Rim size question

[bigguy1]

I just purchased a 2015 Gx sedan. I got the basic package which came with steel rims. I did this knowing I would be purchasing aftermarket rims next spring. My questions are
can I go up to an 18 inch rim without doing any mods? I do a lot of mileage (approx 50,000) a year.
Will an 18 inch rim change the fuel consumption?

Not sure if 18 or 17's would be best. Looking for any input.

Thanks

18's will be fine
No mods needed

Depending on the weight of the wheels you get - it could change fuel economy - But nothing noticeable.

As the others have said, 18's are totally doable without any other mods. In terms of the looks between 17's and 18's, that's up to you to decide. Have a browser through the Members Rides section and you can see some examples for yourself to make it easier to judge which look you prefer.

Thanks for the info everyone. I've been looking at others rides on here. There sure are a lot of nice cars out there.

I will definitely look at 17's as we'll.
