Has anyone fit a 35" spare tire under the GX550?

The Overtrails have a Torsen limited-slip rear differential that is also equipped with an electronic locker. The limited-slip part is what makes me nervous. When I had the lift & wheels/tires installed at Westcott Designs, they completely wrote-off my tire size concerns regarding the 33" spare vs. the 35" new tires on the ground. They said it wouldn't be an issue if you took it easy on the spare and had the 35" tire replaced quickly (i.e. minimal driving on the spare). The truth is that, even with 5 same-sized wheels & tires like I've run on trucks for 25 years, I would always immediately take my truck to the tire shop if I had to use the spare. You go out off-roading on Saturday and you puncture a tire, you take it easy because you now have no spare and you get to the tire shop on Monday morning. Fortunately it's only happened to me a couple times over the years. If I were to have to use my 34" spare, I would take the time to juggle tires and mount the 34" spare on the front axle even if it was a rear tire that went flat. That would be a pain but worth it to avoid upsetting the Torsen limited-slip rear, in my opinion. I'd love to hear that it wouldn't matter one bit, 34" vs. 35" and/or front vs rear.
Center diff is Torsen with locking function. Rear diff is open with locking function.

I've seen the rear listed as Torsen limited slip but I just went straight to the Lexus website and it appears that you are correct - the center is the Torsen limited slip and rear is just listed as electronic locking rear differential. This therefore eliminates much of my concerns....and no need to juggle a flat rear tire to get a good 35" front tire on the rear the 34" spare on the front. Thank you.
