I have my Hankook BIG 33' on my '08 JKU tailgate, but
Although the weight of wheel/tire is 78 lbs, I have Daystar extended bumpstops and the tailgate hinges are "HOLDING", I don't know for how long
Mine's been on about 6 months and you need, AT LEAST, extended bumpstops to minimize the vibration--which starts to degrade the hinge welds !!
Don't doit for looks and plan on adding bumpstops "LATER"---BAM-you lose !!
Gotta be done the first time you mount the spare and I wouldn't attemp 35" tires/wheels, now you're crowding 90/100 lbs--too much for that stock carrier !!
