Bds 4.5 inch lift

Dear friends
I'm not good with computers but hope I'm doing this right.

I own a 2017 Toyota tundra 1794 edition.
Purchased vision Wheels 354 Off-Road Satin Bronze 20x9 +12 5x150mm. I believe they weigh at 37 IBS. Each.

Planning on going with a bds 4.5 inch bracket lift.
Tires will be Michellin Defender LT in 295 65 r20...35.1 inches tall and 11.6 inches wide.
I know just about any onther AT looks better but I have a baby on the way and can't afford to spend more money on fuel.

Can anyone out there let me know how much mpg I will lose with this setup?

Also with a positive 12 offset..how much would my tires stick out??wondering if I need fender flares?

Currently I get about 700km on a full tank...with a capacity of 136 Litres...I usually fuel up at the 650 km mark as the fuel light is on and I don't dare to tempt the fuel gods.

Any help would greatly be appreciated.

If you are worried about fuel, you may want to rethink 35 inch tires. The added weight and reduction in effective gearing is going to reduce your MPG by about 3mpg

 

The michellin 295 65 r20 only weigh 58 Ibs. Do you suggest I would loose 3 mpg....on this setup?

I've been reading this forum for the past few years...and thought I would loose 3 mpg if I chose more aggressive tires like the ko2 or general MTs???

 

Yes, for sure. I lost 1.5-2mpg just switching from the stock 32 inch SL load tires to 33inch E load tires. Both were AT tires. New tires are light at about 54lbs, but heavier than stock and the larger tires effectively reduce the gear ratio- so you take a hit on acceleration. No other changes, stock suspension.

You will certainly lose several MPG running 35s compared to stock MPG. And of course to run 35s, you need to lift the truck which also increased wind drag= so lower MPG. Milder tires like the Defenders will impact MPG less than a more aggressive tire but you will notice a drop in performance and MPG with 35s.

Honestly, the difference in MPG is noticeable but these trucks are not built for MPG and at the end of the day (depending on how much you drive) you are probably looking at +$10-$15 dollars difference in a tank of fuel.

If MPG is a concern at all, keep the truck and tires stock. With a 4.5 lift and 35s you are going to see 3-5MPG less than a stock truck.

 

Agreed

I lost about actually 3 or 4 mpg on a 2"/1" inch lift and at 35" tires. If fuel is a concern. Stay stock or wait till they a hybrid into a these truck one day
