Lift-Wheel-Tire Combination inquiry

Dear all,

Here I come with my first inquiry to this forum

I am a little confused about the lift-wheel-tire combination to choose for my JK. Note that its my daily drive and I will be doing very little off roading.
Now Im sure I will go with the AEV 2.5 lift with the front geometric brackets. But I dont know what wheel/tire I should use;
1. 20 wheels on 35 tires
2. 18 wheels on 34 tires

Thank you in advance for your feedback and any pictures of the mentioned combinations are highly appreciated.

Pics of the wheels Im thinking about.

Run whatever you'd like but remember. Tires are typically more expensive the bigger the wheel.

Please bear in mind that Im running an axle ratio of 3.73
I care about the quality of drivability on the road. Im fine with the price of the tires on 20" wheels (I saved for them for a long time ), but my concern is their weight and sluggishness of the car

Wheel size is not your issue with 3.73's. yes ... A little heavier but the tire size/weight and increased rolling resistance will.
If you are concerned about ride quality, bigger wheels means less side wall = firmer ride. I'm not saying BAD, but increased sidewall will ride better on the road.

I totally agree. what i meant is with the 20" wheel I will be runing on 35", which will make me need to change the axle ratio, am I right??

Nothing says you have to, but with 35's you will lose some mpg/power.

I just put a 3.5 inch re lift with bilstein 5100's on my rig paired with 17inch rims and 35's. she rides better than stock. i have 3.73's but idt it slowed the ride down at all. i put an intake and throttle body spacer and exhaust on to compensate but it actually feels faster. there's not much more hp but the torque went up around 20ft lbs. like i said with this it feels faster than stock so i don't think you'll have any problem with bigger tires. just remember that metal weighs more than rubber so you will have even more rotational mass than me. my rim and tire together weighs about 130 lbs (50 more than stock per tire)

is it a smooth ride on the highway with your setup?? I have a friend with same setup as yours, he complains about the stability on higher speeds on highways..

It has effected my mileage for sure. I also have the 3:73 gear ratio with the 5spd auto transmission and 3.6 pentastar engine. My tire and wheel combo (315/70R17 tires on 17 x 8.5 wheels) are 20 lbs lighter per tire compared to what jetraymond has.However, I have experienced a slight power decrease. It is not as bad if I shift my auto transmission manually. (slap stick) Down the road I think I will regear to 4:56 or 4:88.

yes the stability is pretty good. it's a little floaty, but we also have decent roads in florida. the easiest way to explain it is i don't have to keep two hands on the wheel but i still have to pay attention. i tried going really fast once to see how it handled and it didn't get any worse when i got up to 95 mph

OP - I have 35" tires with 3.73 gearing (6 sp. manual) and overall I'm very satisfied with performance and MPG. That said, I also do that with 17" wheels, which makes for a much lighter wheel / tire combo than you're talking about.
In a perfect setup, I'd like to have 4.10 gearing, which would make 6th gear just that much better for highway driving. But the cost doesn't really justify any benefit. Taller gearing, 4.56 or 4.88 would just be too low for a daily driver. I can just stay out of 6th gear and have the same result.

Go with the 18's and 34" tires. It will look good, and you'll be better off performance-wise. It's a matter of personal taste, but to me, 20" wheels on a Jeep is just wrong. Not only does it compromise the off road capability (which is the very essence of what Jeeps are about) but it just looks bad. But I will also be the first to say it's "yo' money, and yo' Jeep". Have at it.

I agree. Op, go with the fuel wheels in a 18 at the biggest and a 34/35. I think these wheels look the best out of the two. That's what I wanted for my jeep but had to opt for pro comp due to budget.

Thank you all for your interaction and feedback.
Thanks to all of you, and after long and thorough research, I have decided to go with 18 wheels and 34 tires on my 2.5 lifted JKUS. I believe it is a combination that doesnt have too much steel in it, and doesnt have too little rubber either. That will be the most suitable for daily driver to me and little off roading.
I have just placed the order 20 minutes ago .. wish me luck
