Sonora Pas is ~9600 feet, about 300 ft lower than Tioga.
[Edited to add:] I've never done Sonora but I've done Tioga on probably about the same volume of riding as you. However, that was when I was 19 years old and stupid. My buddy and I rode up to Yosemite Valley from the Bay Area in one day, where we met up with his folks who were staying in Yosemite Lodge, so we got to shower and eat well and sleep on soft beds. Then we hiked up to Half Dome and back to the valley the next day. Then we rode up to Tioga Pass and back the day afer. You can get away with a lot when you're 19 and stupid.
