Largest size spare tire fit in undermount carrier?

Thanks, I was able to get it in there but it’s a little crooked and leaning against the bracket.

I have Toyo AT3 E-rated LT275/70R18. When I just cranked it up fully tight, it would not fully seat.

While raising near the top, I need to wiggle rotate, then raise a little. Repeat until fully seated. It's fully seated and appears to the be the max size since it almost touches in the rear.

Thanks, I’ll try that again. I was pulling on it to try to get it to seat properly. May need to air down a bit. Is that what you did?

No air down. My tire tends to shift forward just enough to not seat in the forward brackets. The rubber sort of sticks to the brackets preventing it from fully seating.

By wiggling around while slowing lifting near the top, I could feel the tire move slightly rearward which permitted fully seating in the forward brackets.

Thanks, mine is actually getting caught on the rear bracket. Could be that there are slightly different tolerances car to car. I’m gonna go out and mess around with it again.
