Don't worry, when you add a lift, skids, rack, winch and bumpers you will lose about 5-6 mpg total.
If you are keeping stock size you will only see a few tenths of loss. Everything is additive though.
It's all about your driving habits. Aggressive treads affect MPG for all aspects of driving, so you'll see a small loss there no mater what you do.
Heavier and/or bigger tires affect acceleration; it takes more gas to bring the extra mass up to speed, and larger diameters reduce your torque at the ground level. I accelerate easy, so I probably wouldn't see a huge difference between different weight tires. My wife comes off the line like every green light is on a drag strip. She can't stand it if the person beside her "beats" her off the line. Same with stop signs, and she keeps the same speed going up or down steep hills. With stock tires, when I drive I get between 22-23MPG in mixed city driving. She always hovers around 16-17MPG.
I did a lot of research when deciding which tires to replace my worn-out factory tires; I really wanted to go up 1-2 sizes, but it's her daily-driver and I realized I wouldn't be able to afford her gas bill.
Just for the record...just switched from the stock Dunflops to the 265 Ko2s and am seeing a .8-1.0 mpg loss... even the C rated are some heavy suckers.
When is the "Winter Gas" going to end?![]()
Here is my pure unscientific experience:
I switched from stock Dunlops to stock-size "C" load rating KO2 about 1200mi ago. Since the change, I gained about 0.5mpg (my overall mileage is about 18.2mpg for 70% city driving). How I managed to increase mpg?? It’s all about how you manipulate your right foot.
My previous car was a modified twin-turbo sports car. Since I made the change to this super under-powered T4R, my driving style definitely became much more relaxed and slow-paced. There is no need to keep press that gas pedal because it’s just a noise maker. This change of paradigm on driving helped me to gain the MPG. :lol::lol:

I'd really like to figure out a variable height suspension setup. My inclination is adjustable front coilovers with rear airbags. So I can bump it up for the 2 or 3 trips a year to moab where I really want more clearance and bigger tires. The rest of the time I'll leave it lower. In a perfect world I'd figure out how to build air adjustable coil buckets front and rear so I can run low on the highway and pick it up offroad without losing suspension travel and feel. But for now I'll just have to settle for stock height.
