2022 Tundra Tire MPG?

[M.E.B.]

I traded in my 2015 Tundra. It had 18” tires. At 70 mph I got 17.5 mpg highway. 13 mpg in town.

I purchased a 2022 Tundra a couple of months ago. I was SUPPOSED to get 22 highway and 17 town. I am getting the exact same milage as I did with the older truck with the bigger engine.

The new truck has 20” rims and the mud tires that extend out of the fender wells a few inches. LT305/55R20.

My buddy gave me a set of 20” rims that are narrower If I changed to a narrower tire that’s inside of the wheel wheels does anyone know by how much my mileage should improve?

Thanks

Ya… tire weight, size too many variables if you want more mpg get the stock 18 inch steel rims with some light pirelli street tires

I normally buy Michelin ATX.

These tires came with the truck and after waiting a year I took what I could get.

This is my THIRD Tundra. If I was shooting only for mpg I’d buy a Camery.

But with the 22/17 mpg that was promised I’m just wondering what going back to the Michelin ATX would save me if anything.

Have a 23’ hybrid (it doesn’t really act like a hybrid, more of instance power boost). Reading on FB tundra discussions, bigger tires kill these trucks (well, any truck to be honest). Are you clearing those 33x12.50 without level kit? Did last truck have same size?

what rear end are you turning? 4.10

Promised by a car dealer? By the decal on the truck? Those numbers are for smaller tires than what yours came with I'd imagine. I've never seen true stock 305s on a Tundra. Nor do they adjust the sticker after upgrades.

4x4? You were getting better HWY MPG than 98% of folks who own Tundras....including myself. That's higher than my sticker. 18" tires doesn't really tell us anything. What were the first two numbers? Width and AR/height?

I have a 2022 Trd with 20’s. I avg 16.6 mpg. I probably drive 65% City/35% Hwy. I run the Michelins. They drive great but I do t like the way they look. When I replace them I’m gonna put a level on it and go with all terrains.

I've always run stock size tires on my Tundra. With as many miles as I drive, I've gone through a lot of tires. One thing that I noticed is that the more aggressive the tread, the lower the fuel mileage.

Toyota really screwed this one up. I'm getting a 2024 2500HD Duramax after 1.5 years of waiting on a Tundra. Supposedly it will get better MPG than the Tundra. There's no excuse for that especially considering the Tundra is a hybrid. I met three new Tundra owners, one claimed he got 21 mpg highway, the others were 19. That's just embarrassing for Toyota. One had a leaky pano sunroof, which they seem to put in every single one of the hybrids.

On the tires, the tread makes a big difference.

My 15 tundra 4x4 gets 12.5.

LOL, you expected anything less from Toyota?

As others said, way too many variables to say one way or other how much it would improve. I do know you generally kill your payload if you start pinching down on the tire. I'd bet those rims you are running are not 10.5" to 11" wide, and if the tire is a true 305 (most are not), then you should really be closer to an 11.5" wide rim to get max capacity out of those tires.

The truck has a leveling kit.

It is not a hybrid.

I drive 70 mph on the highway. This is my third Tundra. I had the first smaller truck. The 5.7 now this six cylinder. All three 17 hwy. 13 town.

Driving 5 mph slower buys me about 2 mpg.

I figured someone had bought a 2022 TUNDRA with 18” or 20” narrower tires and had an idea of their gas milage. I already know what the older models do I owned them.

I fully understand what I have is not the optimum tire for mpg.

I’m just trying to figure out if changing to a different tire is going to be worth the trouble and money.

For all of the knowledge being thrown at me no one seems to have an actual mpg number answer.

I've seen a buddy lose a 1mph on a wider tire upgrade so you'd think you could gain one back going the opposite direction. What are you really saving for a mpg or two? You aren't getting 22 with a leveling kit though. Hope that helps

Thank you.
So it appears it’s not gonna be worth the trouble down sizing. That’s what I needed to know.

So the leveling kit hurts gas mileage? Figures.

Accepted the truck as is because it took forever to get one and my old Tundra had around 230,000 miles on it and I was beginning to get afraid it would crap out far from home with no way to get the camper back.

I really didn’t expect 22 mpg but I figured with all the hoopla involved with this new engine there would be some kind of improvement.

I’m pulling a 7K Airstream to Colorado in May I hope these tires are up for the trip.

The width is hurting you the most due to road resistance and the added weight.
