Tioga Pass grade %

If you can make Sonora, you are bullet proof.

Thank you, I did that and find at its steepest the percent grade is 7.6%. Thanks again.

Yes, the Mountain Directory West says 8%, but if you are pulling a trailer with a naturally aspirated (no turbocharger) Jeep, expect to be doing about 40MPH with your foot on the floor for the last 1000~1500 ft of climb. There just isn't enough air up there. The scenery is worth it.. (BTDT)

Need to floor it? Towing an Aliner? Nope. The Jeep will do just fine with that folding trailer.

I towed a 16' KZ Escape TT over that pass last summer with my V6 Highlander, and I didn't need to floor it, either. On the steepest part I may have been as low as 35 mph, but I could have gone faster... I just wasn't pushing it. There are some curves, after all, and it's a long way down.

You're right, the Jeep can handle it OK. I just towed the "A" over Sonora Pass, 26% grades. Was in low gear but not floored. I won't do that again because of braking issues more than power issues. Even tho the Jeep handled it I don't believe in abusing it. I just remembered Tioga as very steep but wondered how steep. 8% grade is no problem. Thanks to all who responded.

Signs at the top warn of grades the next 12 miles (ie to the highway), and then 4% for the next 2 miles. The average (using data from the map) is about 5%. So it's not a 8% slog all the way. The steepest section is probably a 3.5 mile sweeping curve, which is 2 lane with pullouts.

It's 12 miles from park entrance (9800') to US395 (6800').
