Let me rephrase my question I think I asked the wrong thing. What determines how flush your wheels are? Would it be the width? I have OEM tires/wheels currently. Sorry, I’m new car modding so I’m still kinda unfamiliar with the terms and everything.
Width and offset both play a role in determining the placement of the wheel. Offset being more important. The lower the number the more the wheel will stick out, the higher the number the more the wheel will be inside the wheel well. It varies on the width what size offset you want to run. So with a wider wheel you’ll want a slightly smaller offset (bigger offset number) in order for the wheel too fit, without modifications to the suspension or fenders or camber. Ideal offset for this car does vary by what you want to run. If you want to lower the vehicle the tire will then need to be taken into account so that you are not rubbing. And the offset will dictate how far in or out the wheel will stick and that will determine if you need to roll your fenders or not to prevent side wall rubbing. So offset usually follows the wheel size and diameter (For example: 18x8.5 +30, the wheel size is 18’s, wheel width is 8.5, and +30 is the offset). Most popular size for this car being a 18x8.5 +35
So a higher number offset means a smaller offset? That’s confusing. If I’m correct the OEM wheels have a +50 offset. So if I go to a +35 offset then the wheel should be inside the wheel well more then right? But you also said the lower the number the more the wheel sticks out.
Sorry I worded that poorly,
Okay it makes more sense when you put it that way. So I think I’ve figured out that a higher tire width = more low profile looking tires if that’s correct. My next question is how does the aspect ratio effect the way the wheels and tires look. Say for instance I want wheels that are 18/8.5 +35 and tires that are 245/45/R18. How would those tires differ from 245/40/R18 or 245/35/R18?
First number is the the tires width in mm, followed by the percentage of the width also in mm (Ex. 235/40r18 —> the side wall is 40% of 235), and then wheel size. Tire size plays a HUGE role. You want to keep the size as close to stock as possible or you will get a speedometer error. If your tire is bigger than your stock tire then it will make you travel faster than what your speedometer is reading. If your tire is smaller than your stock size then you will be traveling slower than your speedometer. When I say bigger or smaller I mean height-wise (the bigger the middle number the bigger the side wall - 235/40r18)
Should be fine.. maybe some light scrapping with big dips or potholes, but I recommend a 255/35 since that’s less of a speedometer error%, but the Difference is slight
In terms of wheel fitment you will clear it. So no issues there. On stock suspension you can pretty much run anything fine, it’s when you lower the vehicle is where you go to watch out for fitment a little more. Tire fitment will fit the set up, again no issue there. Now depending on your stock tire you might encounter some speedometer speed errors, because of your tire either being taller or shorter compared to your stock tire set up. If it’s taller then it will read faster than what your speedometer is saying, if it’s shorter it will read slowing that what your speedometer is actually reading. We just have to take a look at the speedo error % to see if it’s a good overall fit. What is your stock tire size?
my stocks are 215/55R16
I’d recommend one of these two sizes as it has the smallest error % (you want to be as close to 0 as possible). Which ever fits your budget will be best but these are the 2 sizes I recommend choosing from: 235/40r18 or 255/35r18
I would think you should be just fine. That's not a really aggressive fitment at all.
