I am looking at buying a set of wheels but he says they are 5x100, i'm pretty sure the caliber is 5x114.3 , I dont know alot about fitment but will the 5x100 fit the caliber? I need some answers asap, I will try to post pics, I think these would look awesome 245/40/18

Well, someone here has Dodge Magnum/Charger rims (Amandyke I think?) and those are 5x115 ... I find it unlikely that 5x100 will work.

You're better off going 225/50/18, the setup you're considering (IF THEY FIT) would give you a hard ride. Not to mention the stress on your suspension and other front/back end parts.

I agree 100%. I have 235/50/18 tires on mine and the work great!

Pics please calibered!!:D

Also, do the 235's give it WIDE LOOK?

*edit* Nevermind the pics Calibered, I see you have some posted in another thread...

5x100 will not work.

And Steelblue, 235 isn't that wide, 245 would give you a better "wide" look (with the added bonus of better handling as well) over 235, 225 or 215.

I don't see a problem with fitment on a 245 either so long as you get a proper offset on the rims.

I am curious about something.

If the tire size reads like this: 235/50/18

  • Is the first number (235) is the width of the tire. Is this in mm?
  • I do not know what the second number (50) stands for.
  • The third number (18) stands for the size of the rim the tire is designed for.
If any of that is right/wrong, please let me know. I am just curious as I am just now getting into cars and have some rather noob questions. I have never went to buy tires and do not know what each number stands for.

Yep, for any tire that starts with "P" (such as P235 40 R18) the following apply:

The first number is the tire's width in millimeters. So, 235mm is 9.252 inches.

The second number is the width of the tire's sidewall as a percentage of the width; this is known as the aspect ratio. So the aspect reatio of 40 is 40% of 235mm which is 94mm. Or... the 40 aspect ratio is also 40% of 9.252 inches which is 3.701 inches.

The last number (with the R-prefix) is the diameter of the inner circle that forms the bead where it contacts the rim. This would be 18 inches

So, you can get arolling diameter of the tire of 18 + 3.701 = 21.701 (notice how I don't count the tire's width in the calcuation of the diameter since the width has nothing to do with the diameter of the tire.)

Most of the time, you want your new, fancy tires to be the same diameter as the stock ones The first reason is that this means you don't have to recalibrate the speedo. The second reason is because your tires are basically the "final" gear that comprises the transmission. Yeah, there's a final drive gear in the transmission, but if you think about it, your tires spinning are also a gear. Increasing the tire's diameter will also affect your accelleration (to a slight extent).

It's probably impossible to match up the diameter exactly when you go to aftermarket wheels, but a change of +5% or -5% seems acceptable to most people.
