Hi all! i am new to this forum, however, i am not new to forums in general so i will keep this brief. I just got an 04 ranger supercab fx4. It is my first truck and I am excited. here are my questions:

Please just post a link that would explain tire size and such? my stock tires are 245/75-16. they are worn and need to be replaced. a bigger tire would be nice, but i know nothing of this topic. with a 16" rim, and no lift, what is the max size i could go? again, if you dont feel like educating me, just post a link.

Also, i have read on here that you can get 1-2" of lift just by tinkering with the suspension? how is this done? is there a diy link or anything? how will it affect the ride of the truck?

thanks in advance for any help that i get. I am just currious and beginning to learn about all of this!

Thats the link to the stickied post on this section, there is a chart showing approx. what you can do

 

The 1-2" lift you are talking about is cranking the T-bars.

ok thanks guys. so then explain tire size to me. i looked at the stickie and saw different tire size recommendations. i know that my tire right now is 245/75-16. all i know is that the 16 is my rim size. which of the other two numbers would need to be increased to make the tire taller? i just dont understand yet.

 

The 245 is the diameter of the tire and the 75 is the width of the tire. Just look on the chart posted above for the max tire size with tbars(torsion bars) cranked and there ya go!

 

the largest size tire u can go with no lift and stock rims are 33's.. if u dont want that big of a tire.. run a 31in tire.. i had 31x12.5x15 before i lifted mine.. and loved them. just wasnt big enough for me

 

Metric Tire Break Down and conversion Standard
Your tire is LT 245 / 75 R16 heres the break down in order

Type - LT = Light Truck

Tire Width - This is the width of the tire measured in millimeters from sidewall to sidewall. An example might be 245 representing 245 millimeters.

Aspect Ratio - This is the the ratio of the height of the tire's cross-section to its width. An example of this might be 75, which means that the height is equal to 75% of the tire's width. To calculate the aspect ratio, multiple the first number (e.g. 245) by the second number with a decimal before the number (e.g. .75). Using the example numbers the tires aspect ratio would calculate as 245x.75=170 where 170 is the tires height in millimeters. This is the height of the rubber from rim to tread on one side of the tire.

To convert the aspect ratio to a full tire height in inches, do this:
Convert the above calculated tire height (aspect ratio) in millimeters to inches by multiplying the millimeters by .03937 (170 x .03937 = 6.5 inches). Then take the inches and multiply by two and add the rim size. Example: 6.5 x 2 + 16 (rim size in inches) = a 29 inch tall tire do the same for width (245 X .03937 = roughly 9.50)

Rimsize = R16 your rimsize equals the number that fallows r in the code

so in comparison LT 245 / 75 R16 = LT 29X9.50R16

my sorce if you wanted to read all of it (sounds like you do ) http://www.offroaders.com/tech/AT-MT.../tire-tech.htm

just copy link into browser as i dont know how to make a clickable link

 

I feel like a tool aparently it makes itself a clickable link who knew

 

thanks for the posts everyone! that is exactly what i was looking for!

 

hey, i dont know if this has been posted, but its good for explaining how to do a tbar crank. it also talks a little about tires

bzzzzzzzzzzzzzzzzzzzzzzz wrong.

Nick did a great job of describing it.

245 MM is roughly 9 inches. and 75 MM is roughly 3 inches

9" diameter and 3" thick.....what you have there is a tricycle tire

 

I used this for my ruff geussing of tire size:

I had the same set up as u, 04 4x4 245/75/16 I went with 265/70/16 thier not as tall as the 265/75/16 and their cheaper.... i got the general grabber at2's as well... for $90 a tire at tirerack.com

 

If you do the tbar crank for front end lift, what about the back suspension? I am looking to add helper springs to decrease sagging when my Ranger is loaded or towing. I am going to do the tbar crank also. I currently run 245/75-16 tires on stock alloy wheels. I don't care that much about changing tire size,that is unless someone can explain the advantages of larger tires. I guess the body lift and larger tires would increase ground clearence. My stepson has suggested going to steel 15" wheels with 31x10.5 tires if I recall the size correctly. What is the advantage of this setup? I'm new at all this modification stuff. I drive anywhere from 15-25k miles per year. Probably 7875/25% hiway to offroad. I am also going to buy new tires soon. I'm really liking the Kumho KL-78 tires. Here in Colorado I have to deal with mud and deep snow so I like the Kumho based on the survey at TireRack. I've also read and heard a lot of good things about these tires and brand.
Any hints,info, etc. appreciated.

If you are looking to stuff the wheel well with a tire you can fit a 285/75/16 which is roughly a 33x10.50 but your problem will be that you will wear down the center of the tire because of how narrow your rim is(16x7). A 265/75/16 would be my choice beacause its a bit taller than your stock tire and will wear fine as long as you keep a good air pressure in the tire.

 

WRONG dont listen to that. 75 would actually be a ratio of the amount of profile on the tire compared to its diameter or width i believe. lower numbers will get wider, and less profile tires (I THINK) it seems like an absurd measuring system though

 

On a stock ranger if you dont want to mess with the suspension and want dicent fuel mileage, go with a 265/75-16 (32 roughly +-). If you Get chevy shackels, and turn the t bars about 3-4 turns, you can get a 285/75-16 (33 roughly +-)
