How Big Can I Go?

I have a 2002 sunfire 2dr. and i wanna get some rims. I know 17" are a sure bet, but would i be able to get 18" in there with no rubbing or modification? if so, what sizes?

thanks!


also, if you have a sunfire/cavalier with 18" rims please post a pic i would liek to see what they look like, preferably with a mr7 style look in hyper black on a red car ;) lol

Just go onto the discount tire web site and see what the max is that the stock specs can handle. They like to play things safe so they dont get alot of complaints so what ever series tires they say can fit onto 18's will be a sure bet.

Fitting an 18" rim won't be a problem but you'll probably need a lower profile tire.

18s will fit. Just use 225/40/18 tires and you'll be good.

Also you can go to www.wheelmax.com and put in your info and it will tell you what will fit your vehicle......

biggest w/o changing anything or rolling fenders are 19"s with 40-42mm offset and 225/35-19's.

thx for the replys, awesome info.

I hope you relieze that swaping to a larger rim you will end up making the car slower

Not if you buy Motegi Trak-lites.. :) Even the 19"s weight less than stockers... ha ha. But then again not everyone can afford 250+/ rim.

19's on a cavalier... or even 18's good lord why.

your ride will be crap, and itll look down right retarted to boot. :icon16:
im sure someone will say differant but if your going for performance 16" is a good bet to go, and handling you wont see a noticable differance between 17-18. the wider 17x7 tire is great for handling, better than an 18" wheel...

my friend has 18's with 225/40 and its lowered 2 inches and it looks hot

i have 16" rims on 205/50's and i float around the mean streets of riverdale... 16 isn't that big but it looks big on a cav.

not everyone is about speed, speed limit is 65mph, you can hit 65 mph with no problem with 18's, hell, even 19's

personal opinion i guess, i think it looks stupid becouse there is no performance benefit. a complete waste of money to impress the 1/100 people that actually think big crazy rims are cool. like i said tho, personal opinion, its not my car, my post was refering to performance as this is the performance section.

true but you mentioned the looks so i added my two cents.

charging the rim size does not charging the tire size?

For example, tire mounted on a wheel,
(1 inch=2.54 centimeter)

P205/60R-15, the whole semidiameter = (205×0.6)+15×1/2×2.54=31.35 cm
P225/35R-19, the whole semidiameter = (225×.35)+19×1/2×2.54=32.01 cm

The size change not more than one cm, but the rim change 4 inch.
The difference between this change will be the rigidity when driving,
AM I RIGHT?
I am also wondering what size of rim I can choose.:licka:

225/35R-19s would be 225mm(8.85" width)*.35=78.75mm(3.1" sidewall)*2(top and bottom)+482.6mm(19" wheel)=640.1mm (25.2" overall size)

compare that to 205/60R-15s, the outcome would be 627 mm, or 24.6" for the overall size, a change in roughly .6 inches, or 1.524cm. so yes, you are close in the idea that the overall tire size doesn't change drastically, but the rim size does. you just took a different path to come to the same answer.

wow, well im glad i didnt have to break out my mad calculator skills to figure those two out. couldnt u have just said that as the rim size increases, the tire size decreases and that the overall differences is not that much? there. easier to read than math...

Yeah, U R right, :licka:
I just wanna make sure by myself, the more your do, the more you understand:naughty:
