Street Killer

So, I have beat ideas for my Liberty till I have no more. So, with a 2WD and no possible way to trade or sell it with my negative equity, here is my plan:
Since she is 2WD and terrible off road, Im going the sleek and mean route with staggered wheels and tires. Im not going to lower it, just keep its OEM height. Since she is black, Ill go with black staggered wheels like 18x9 rear with 255/45-18 and 18x7 or 8 front 2ith 235/50-18. They are the same height so the computer will not be confused. Now let me repeat, this Liberty is a 2WD! Suggestions?

Maybe you can do some cool paint schemes with plastidip. I've done a few things, but it can really help ya bring out your creativity and give the Jeep personality.

Just thinking outside the box here.. Any additional funds you'd spend.. Why not use it to pay down the jeep. Before you know it.. You'll be getting a 4wd Libby on trade in.

have to remember that even though two different size tires are the same height, installing them on different width wheels will change that height somewhat

All depends on size, for example a 255-70-16 has a tread width of 7.4 inches, a 255-45-18 has a tread width of 9.1 inches
Good bit of difference

What? I thought 255 was the tread width in mm (255mm = 10.04") where did you come up with those numbers Tom? Not saying I don't believe the guru but that goes against what I've learned about tire sizing

In a perfect world possibly it may be that way but not in the real world. It can get very confusing, but....
The second number on a tire size refers to the aspect ratio: This is the ratio of its section height to its section width. The smaller the number, the shorter the sidewall and the wider the tire. In other words, a 50 series tire is shorter and wider than a 60, even though they both might be 255's or whatever size you are discussing . A 85 series tire will be very narrow compared to a 75 or 70 series and on down. So just for discussion sake, a 255-85 maybe 7 inch tread width, whereas a 255-45 maybe 9-9.5 inches

Hm... I'm not so sure I follow your logic. The first number is the section width, the second number is the sidewall height as a percentage. So for a 255/65 my understanding is that the section width is 255mm and the sidewall height is 65% of 255 or 165.75mm (255*0.65). I have 255/65R17 so my overall tire height would be twice the sidewall height plus a 17" rim (431.8mm) SO: 165.75+165.75+431.8=763.3mm or 30.05" (which is what the original height of the tire was before tread wear).

So I know you understand aspect ratio but I don't understand how you say "The smaller the number, the shorter the sidewall and the wider the tire." Where did you come up with this?

I guess the smaller the sidewall height the less it will bow out (which will change the overall section width) but that is the inverse of what you are saying.

Section width is not tread width,2 totally different parts of the tire.

You can change section width by simply mounting the tires on wider or thinner rims.The advertised section width(say 255/70R16) is measured on a specific rim size in which they will list on the company's website(what rim sized used to measure).The wider the rim the bigger the section width gets and the shorter the tire gets.Mount on a narrow rim and the section width decreases and the tire get's taller.

Tread width is different from section width. Check out this tire from Treadwright's website:
https://www.treadwright.com/p-34-245...den-a-t-e.aspx
This is a 245/75/R16 BFG-A/T ~like tire.

Tread Depth:
16/32”

Meas. Rim Width:
7”

Tread Width:
7.9”

Rim Width Range:
6.5-8”

Max Load:
3,042 lbs

Outer Diameter:
30.7”

Max PSI:
80 psi

Section Width:
9.8”

I think TireRack.com lists all the stats on their tires as well.

May I suggest you go to Tire rack for example , pick a size tire say 255-70-16 and look at the tread width, section width etc, then also look at the specs for say a 255-75, 255-65, etc . You'll see more what we are trying to explain.

You would of really been confused back in the day, when we went from numbers like 8.25X15 to G78-15, ( same size tire) the old guys didn't want the new sizes since they were different and their car was suppose to have 8.25 not some letter Then the radials hit in which made it worse , then metric sizes
