I have 18" MB Predators on my truck:

18's are a good size....i went from 16 to 20 then to 18

weight will depend on manuf. and style....sadly...the lighter you go...the higher the cost

my 18's are lighter than the stock 16's that came with my truck, unfortunately...i cant get a taller tire because of the width...(for the rear)

sidewall height will either make the wheel look bigger or smaller.....color of the wheel too, no one could believe that my 20's were 20's, but thats because they were powder coated steel blue and had 275/40/20 tires

You sure I thought it just measured the heght of the tire? Well thye are 255/55/R18's anyways.

yup, he's right. incase you didn't know, the middle number is a percent of tread width.

when they say a tire is 255/55/18, that means:

255 = tread width in millimeters

55 = sidewall height, as in, 55% of 255

18 = rim size.

so, a 255/55/18 is 29" tall, with a sidewall height of only 140.25mm and a 235/55/18 is only 28.1" tall, with a sidewall height of only 129.25mm.

and no, I'm not rainman, I wrote a calculator program in excel that shows me all these numbers, all I type in is the size like 255/55/18, and I get sidewall in mm, sidewall in inches, diameter in inches, circumference in inches, circumference in feet, revolutions per mile, and distance per 500 revolutions.


I did this so I could figure out what my speedo was really telling me after swapping tire sizes to a non-factory sized tire.

you might want to check that quote...i never stated that...

I know what you said. you said "55 doesn't mean anything without the width"

so then mthandt said "are you sure about that? I thought it was the sidewall measurement"

all I did was click "quote" from mthandt's post, so not sure what happened there.

2/3 Drop 255/55/18 rims 18x8.5 Panthers

 

[moore_716]

Here is the calc I used.
http://www.dakota-truck.net/TIRECALC/tirecalc.html

My truck has 255-50-17's front and 285-50-18's rear. Basically a 2-3 drop but I can alter the rear about 3/4" with the air shocks.

 

[silverbullit]

18s in my sig, stock height truck with no drop!

 

[domay11]

Where'd you get em?

 

[porksoda]

Where'd you get em?

It used to be Discounttire.com but I believe they are discontinued those are the ones I wanted. Try calling discount maybe they can do something.

 

[Mopar4Life]

This is a fine example... 18x10s all around with 295/45 front and 305/45 rear
