MPG affects

Does anyone have any recorded results of MPG gained or lost after lifting truck 3 inches and putting 33" tires on? If so did you swap gears?

 

There are many threads on this topic. With 3 inches and 33's, you're going to take a big hit on MPG's. Lower gears may help recover a bit, but the extra tire weight is inescapable. I'd say 12 to 15, depending on driving style. Some do better, some do worse.

 

Those mods will have to wait... she's going to be my daily driver for a while (50 miles round trip)... Thanks.

 

Fuck, I have to:

On the actual MPG hit, absolutely you're going to take a hit. How much depends on a TON of factors, but I agree with SoCalSteve up there - it's going to be significant from stock to that. Some guys will have less effect, some will have more.

Good luck, and let us know what you do!

 

I'm waiting for someone to buy a Corolla and LIFT it significantly.

What will the MPG look like afterwards? Do check back in with your results.

 

Too many factors. I would say I lost more MPG just by equipping armor on my truck more than throwing the lift and all terrains on it. More also doesn't mean I lost tons either. On the highway I still could do roughly 350 a tank boosting it to get to speeds and all. The city is where I take a mild hit. I get about 15 when I drive mostly city and some highway. About 230 a tank most of the time.

 

With stock 245/75 tires, I was around 19 average (20 highway and 19 mountain/ town) This was before my truck was laden with tools, topper, sleeping platform...

For a couple years (with above mentioned extra weight) I ran 265/ 75 load C snow tires in various stages of wear. Good tread for winter use, and I ran the ones that were pretty worn down in the warmer months (snow tread, soft compound, etc..) and averaged 16.5 in winter and 17- 18 in summer. These numbers stayed constant with the addition of 2.5" lift.

Now I'm running 255/85 load E (still with all of the extra weight) and I averaged 18.5 all summer. So far, I seem to be around 17 for the beginning of the winter. I had a tank go 15, but there was about 50% mountain highway driving in that one.

I have 5100s set at 1.75, which yielded about 2.5 actual lift. I have stock UCAs and LCAs, as well as stock rear leaf spring and stock gears with manual trans. My rear lift comes from my Firestone air bags on cradles - which rides fine with all the weight and Nitrocharger shocks.

Towing and mountain highway driving seem to affect my MPGs more than any other factors now that I'm running heavy 33s. 4.10 gears would help in those situations.

 

I put a 3" lift on mine but kept the 31" tire size. Absolutely no impact on MPGs at all.

The tire size increase is what will hurt mileage. Bigger, heavier tires require more energy to move.

 

Nope.

I'll even go so far as to say not even possible. (caveat being the stated mod is the only thing done; comparisons before and after are actual calculations over several tanks, not someone's MPT swag)
