ah makes sense, I was just curious as I'm in the process of purchasing a level kit and I don't haul much. Im thinking the 2.5 front 1" rear.

Here is how you calculate tire sizes to a number you can understand.

Stock Size = 275/65R18

*The 275 represents the WIDTH in millimeters.

*The 65 represents the percentage height of the side wall compared to the width. So 65% of 275mm is the size of the side wall. Just remember you have two side walls with measuring a tire.

*The 18 is wheel size.

So with that being said there is 25.4mm in on inch. So 275 divided by 25.4 is 10.826. This means your tire is 10.826" wide.

Now you need to calculate the side wall height. To turn the percent (65) into a number put a decimal in front of it(.65).
So 10.826" X .65 = 7.037", there are 2 side walls so you now multiply that by 2 which equals 14.074". Now add that number to the rim size. 14.074 + 18 = 32.074.

So a 275/65R18 = 32.074" X 10.826"

if you are looking to get different rims as well, you can get 20x9s with a 0mm offset. I put a 305/55/20 tire on mine and have no rubbing..


I like it at least.

What block did you use in the rear?

Thanks in advance.

2.5'' level with 305/45-22 tires. No rubbing. Wheels are 22X9.50 with a +25 offset.

[QUOTE=Dtown;4603094]2 1/2 rough country level, 285 75 r18.. No rubbing and drives great.

They look great! Do you get a lot of road noise? How is the ride different?

Question, how many of you guys who have leveled & put bigger tires on go 4 wheeling to some extent & compress your suspension & hyper extend it?

When you do this, how id the rubbing, any issues?

Spent a few hours today talking to a couple different 4x4 shops about leveling and what they see/recommend.

F150 lifts was mentioned, go to play with blocks, spacers and other pieces parts & the shops all like those products, say they have never seen any come back to the shop jacked up or the vehicle jacked up & the people who re running em all have good things to say.

I'm going to have one of their lifts installed & go middle of the road larger BFG/K02 tires on stock 18" rims as we do 4 wheeling in remote areas & need a system that can take abuse and hold up.

My ranch is very remote, very ruff, some aggressive climbs and descents on trails with loose rocks ranging from softball to a little bigger than basketball, along with lots of 6"-18" ledges. I have 295/70's, mine measure out to 34.9" x 11.25" on my factory 18's. I had about 3 areas where I would drag bottom before the level and tires, one of them was a pretty good hit because I was on a pretty steep decline while going over a 1'ish drop off. After the level and tires no hitting steps or skid plates other than on one steep break over by the pond, no way around that with the length of this wheel base length. At full compression in a pretty harsh flex I got a tiny bit of rubbing on the crash bars at full lock. Never touched the inner fenders, or the mud guards.

To put your mind at ease, I'm 21 miles from the closest paved road, 5-6 miles from the closest cell phone range, and no neighbors for several miles in any direction. Just think remote south/central Texas and multiply it. If my ride wasn't 100% reliable, if I thought I was going to rub a tire to failure, break something, or get stranded I wouldn't drive it out there. My truck is just 2" in the front, didn't play with rear blocks at all, still has a slight front rake. One thing I can say about these trucks is they are pretty impressive for what they are, in an off-road sense. There are 2 trails my buddy can not drive his Jeep TJ up. He is no lift on 33's and no lockers. I drive a tank basically compared to him. Lockers and good suspension make a word of difference. It will keep the wheels planted pretty well and locked rear helps a lot when you are dealing with ledges and large loose rocks.

Side note, mud guards are 100% effective at keeping mud and rocks off of the paint with the factory wheels. Since they don't stick out nothing made it past them and hit the paint at all.
