Ramp Travel Index. It's a measurement percentage of the wheelbase vs the up travel of the tires on the ramp/ground before one tire comes off the ground. If you travel 1/4 up to the wb, you are 25%. If you climb all the way up, you reached 100%. If you have to approach the ramp at an angle so that your rear tire doesn't climb the ramp, you've better than 100%, numbers of 1050, 1100, 1150, etc. It's still a percentage but represented as a whole number.

23 degrees was the initial fame in the 90's. Now there are trucks maxing this out easily, so 25 degrees was next and since it wasn't a drastic change in degrees, easily conquered. Now the theme is 30 degrees.

Well, not exactly.

RTI is bases comes not from th distance in inches or feet you travel up the ramp, but rather it is based on the wheelbase of the truck.  A 1000 score is based on traveling up the ramp the same distance as the wheelbase.

If a Truck with a wheel base of 88" traveled 88" up the ramp before lifting a tire, that would be a perfect 1000 score.  If the next truck had a wheelbase of 100", and maxed out a 88" on the ramp, it's score would be 880 RTI.

Here's the fomula:

Distance traveled in inches ÷ wheelbase in inches x 1000 = RTI

There are many different degree ramps, from anywhere from 20* to 35*.  The more the * in the ramp, usually the lower you RTI score will be.

Ramping 1000 on a 20* is MUCH easier than on a 35*.

Hope this clears things up.

I've always heard that rather than distance UP the ramp, it's how high your tire is lifted in the air before another lifts off the ground..., with wheelbase taken into calculations

That way, scores are actually comparable regardless of the ramps degrees...
