What is the degree of incline of these ramps?

As I pointed out in my review the ramps rise 1 inch in the vertical for approximately every 3 1/3 inches on the horizontal which equals a pitch of 3.60. This translates into the grade of the ramps being nearly 30 percent.

I don't have the ramps, but using muleskinner's numbers of a rise of 1 inch in 3 1/3 inches, that would be an angle of incline of 16.7 degrees. (angle = atan(1 / 3.333))

Should work fine. My tires are 255/40-17 (approx. 10" wide). No problem with ramps.

Level 0 equals level and level 15 raises it about 6 inches. It is a very steep incline for working out. As to declining, it will go back to the level position; it does not go lower. For a good workout, have it go up and down during the workout.

Whatever the measurement of your front bumper to ground, just add 6 1/2 inches. Example, if your front bumper is 6 inches off the ground, the ramps will put the front bumper about 12 1/2 inches off the ground as long as the ground is flat and even.

I've slid down it several times. I am about 150-160. I didn't have any problems from an incline of about 3.5 feet. If I were pushing upwards of 180-220, I'm not sure I'd get it without some central support.

I am not sure why they list an "unoccupied" rise specification. Better to ask the manufacturer. I do know it will safely hold an incline of six inches. Hope all goes well for you. God bless the disabled.

It will be outside the design specs (and building code) for the prodiuct. The rule of thumb is 1 foot per inch of rise so you really need an 8 foot ramp.

I really don't know. I gave this as a gift to a beginner along with a ramp. Sorry!

For me, I measured the length of the ramp then took a 2x4 put it up against my vehicle then imagined how steep it is. The less steep the better. It also depends if your land is flat or sloped. My dog has since passed so we now use it as a training aid for agility. I hope this helps. Feel free to contact me again. Best wishes to you and you buddy!

Not sure. Measure how far the front of you lip is from where your front tires hit the ground and how high your lip is off the ground and I'll go measure the height of my ramp at that distance.

They are advertised as 1500 lb., so if your stuff is less - you are okay. These are good ramps, and I highly recommend this set over the other ramps like these out there.

If you put the safety catch in the last hole in the rack, they are 22" from the ground. I've done declines with no problem, but I have an Ironmaster bench which is a little higher than most weight benches. I have had more of a problem doing inclines, though, because the lower set of J-hooks doesn't go high enough, and the higher set of J-hoops attached to the adjustable bar don't go low enough. There may be a happy medium I'll find after more experimenting, but for now I'm doing inclines with dumbbells. Hope this helps.

At an incline of 15, the foot pedals are 18" off of the floor. I am 5'5" and at the highest point, I measure approximately 83" from the floor at the maximum workout height.

I suspect the incline angle you are attempting to climb is greater than the angle recommeded by your chairs manufacture. I suspect t

About 15"-17" if your feet are at the front of the pedals. No higher than 21" depending on where you prefer to put your feet on the pedals. The measurement ranges reflect different incline levels that can be manually adjusted.

It has two ramps or a pair of ramps so that a wheelchair can roll on it. I use mine for my father, but measure the length you need. I have 4 steps, and it is a harsh incline. Otherwise, very great ramps, very sturdy!! Hope this helps!

Depends on how high your tailgate is...assuming height is y feet and hypotenuse is 8 feet, solve this equation:arcsin(y/8) which yields your ramp approach angle. If your tailgate height were 4 feet for example, then the angle would be 30 degrees.
