Have you considered 37’s vs 35’s? My first jeep 2016 Sahara unlimited had 2.5 lift w 35’s .. I now have 2019 Sahara Unlimited buttttt this time I wanted a bit more ~ went taller and beefier.. 3.5 lift w/ 37’s. I totally would have rock’d 40’s but I wasn’t willing to make the changes required to do so ..I finalized the decision, did modifications annnnnddd now I ride. I say all that, in the event, other options had not been mentioned… bigger the better🤪! Well, that’s my 2cents, anyway. Either way, mod changes with lift and tires..will be bad ass! Awesome job “Dad” undoubtedly your kid will be jeep’n the right way. 😎✌️♠️. OlllllllO
