The eight speed transmission fairly easily soaks up the change in tire though you lose 8th unless going downhill. I have a Rubicon with 4.10s. I'm sure 3.73 or less would be a poor experience. Having said that, I'm upgrading to 4.88s, mainly for towing, but also to regain 8th. I'm still getting about 16.5MPG with 37s. I've got them inflated to 30PSI.37s for a daily driver? I'm thinking the hit to your mileage, gearing (if you haven't already upgraded), reduced braking effectiveness (from the reduced leverage and higher rotating mass) and the sheer amount of sidewall flex (unless you are running 20s) is going to make for an unpleasant daily driving experience. Or maybe those compromises are all OK for you which is great - you do you of course. I daily drive on 35s and honestly I would not go larger. Even with corrected steering hardware, proper tire inflation and quiet tires I feel like my JT on 35s (I also have the Mopar 2in lift) is at the limit of what I consider all weather all road/traffic conditions daily driver that I can still drive through a swampy ditch on an illegal u-turn. But - again - just my $0.02. Interested to hear your experiences after a couple of months. Thanks!
It's imperative, IMHO, that you get 35"+ tires road force balanced by a reputable shop.Just put BFG KO2 37s on, primarily daily driver. Went with these for weight and reputation. I think my case was rare, would love to hear from others if not, but they were a bear to get balanced, highly recommended buying local and not internet so they will work with you. However, now that they are balanced, the ride awesome. The 37s may be rougher on ball joints for example and I am not aware of it, but it is all in what you want I guess. Heavy 35s may be rough on things like ball joints too. I was hesitant about 37s and almost went 35s, glad I did 37s now.
So I already stated I will be re-gearing, even if I decided on 35s I will re-gear, so the mileage concern and re-gear cost are a mute point in my situation. So we are down to sidewall flex on 17' wheels and reducing braking as the points being made.
Just to be clear I did not mean any disrespect. I love that everyone gets to do whatever they want with their own rig - your wallet is your only limit. I just see a lot of pics on here of 37s and 40s and it makes it seem like "most" folks are running that kind of gear but on the road almost all JTs I see are running factory rims on what look like factory tires. Maybe they go for more aggressive tread patterns or move from their sport/overland wheels to rubis or something (OEM+ vibe) so I just wanted to put in my $0.02. I think it's a good idea that you are seeking opinions too but you'll be happy with whatever you choose. Best of luck!All good points and that is why I'm asking questions. I've been going back and forth between 35s and 37s. Thanks for the input.
Just following on 2 things:So I already stated I will be re-gearing, even if I decided on 35s I will re-gear, so the mileage concern and re-gear cost are a mute point in my situation. So we are down to sidewall flex on 17' wheels and reducing braking as the points being made.
Since we are talking about a total of about 28lbs total on average, depending on brand, between 35s and 37s is braking a real concern? If so, unless I just haven't searched correctly, how come I haven't seen numerous posts about brake issues and upgrading the brake system?
What exactly is the concern with sidewall flex? My understanding is a tire with a little more flex leads to a smoother ride which is what I would like as a daily driver.
Both are legitimate questions that I would like to see feedback on if you have any or can point me in the right direction.
Be assured that I didn't take it as anything but things to consider. If I didn't want to hear what everyone thought I damn sure wouldn't post anything on these boards!!!Just to be clear I did not mean any disrespect. I love that everyone gets to do whatever they want with their own rig - your wallet is your only limit.

PS - I admit that if I had a diesel and an automatic I'd feel a lot different. The low end torque and the even gear spacing gives you much more flexibility so your only compromises are high speed behavior and braking. But if you have the 3.6 I'd suggest you drive it first...
