I have 2019 wrangler sport with 3.45 and want to replace my 245/75/17 with 285/70/18. What ratio do you recommend.
A 285 70 R18 Tire most commonly will measure 34.8" so 4.56 is likely best. Be sure to refer to our gear ratio guide for larger size tires http://www.quadratec.com/c/reference/best-gear-ratio-when-adding-larger-tires Thanks for your inquiry.

So, I have a '18 JLUR. I went to 35s and added an aluminum clamshell RTT, so the jeep got kinda heavy and im currently in the 15 MPG range and rarely see 8th gear. I dont know if I should go 4.56 4.88 or 5.13. I'm looking for mostly mpg savings as I actually do well offroad now, but will also take my overland trailer out, about 1,500 to 2000 lbs depending on loadout. I would like to see 8th gear again and a couple more mpgs. Any advice?
With 35's and needing added power for weight considerations, 4.88 would be the most appropriate selection. Thanks for your inquiry.

Would you want 4.11s for 33 inch tires?
Yes. Anywhere between 4.11 to 4.56 for 33 are good options depending if you are seeking more economy with the 4.11 or more power for towing a 4.56 could provide. Thanks for your inquiry.

I just put 34” tires on keep gladiator high altitude. Do I need to change my gear ratio from the current 3.73?
4.56 is the correct gear ratio for best drivability with a 34" tire size. It is not a requirement but highly recommended. Thanks for your inquiry.

2019 rubicon with 37 tires thinking about 538 gears what would be the best gears for power and mileage
If power is more needed than fuel economy the 5.38 will be a better option, but 5.13 will give the best daily driver power curve and better fuel economy than the 5.38. Thanks for your inquiry.

if i have a jl 2018 blonde i can put 37 inch tyres and install this 5.13 kit ? what relationship would you recommend me ? 4.88 or 5.13 ?
5.13 if you wish for more power in towing and torque needed driving conditions. If fuel savings was more important, you may opt for 4.88. Thanks for your inquiry.

I’ve got a JL Sport Dana 30/35 with 3.45 gears, will I need anything additional going directly to 4.56? maybe carriers?
A carrier change is not needed for re-gearing on JL models. Thanks for your inquiry.
