New Tires; Worse Gas Mileage. Anyone Else Get This?

[ClemsonU88]

I'm sure I'm not the first guy to post something like this, but I didn't see any posts specific to this topic when I searched, so I'm posting one now.

After my last recall/computer update, I was regularly getting about 51 mpg with my 22 Hybrid Maverick XLT. I got new tires last month, and my mileage is now regularly around 48 mpg. My new tires are the same dimensions as the old ones: 225/65/R17. I got Montreal Eco-2 tires from Wal-Mart.

Has anyone else experienced this kind of difference in gas mileage after replacing your original tires with the same size tires? I'm wondering if it's the tires or if they reset something that was updated in one of the recalls. Any thoughts?

Probably the change in tread pattern/aggressiveness. If so, other than return them for something less aggressive there's really nothing that can be done.

This might be the problem...........................................

i recently replaced the factory continentals with different continentals and noticed this. i assumed it was due to the difference in weight from a worn out tire to one that was molded to a full 12/32" tread.

It's not walmart, it's the tires.

I've bought cheap tires at walmart and more expensive ones. He bought $67 tires:

Without looking up the detailed specs on the tires you purchased, it's possible they were not designed for hybrid vehicles. They might weigh more etc.

Also, check the pressure, walmart probably inflated to 35 psi (door panel) but you can safely push to 40-41 psi if desired and you want more mpg (check sidewall).

It's also possible there is a slight difference in diameter throwing the odometer off a bit, I bought some different continental tires for the front of mine & even though they are the same exact size, they are slightly smaller, check to make sure the new tires are maybe slightly taller. The difference in mine threw the speedometer off 2 mph at 60, so the odometer is off that much too.

Buys a cheap set of tires and complains about a 3 mpg difference. Not trying to be a jerk but that's hardly anything to worry about

I suspect the OEM tires are built with low rolling resistance in mind. They may even be manufactured specifically for the Maverick hybrid. The Walmart tires are generic, so they were surely not made for hybrids.

New tires can initially lead to worse gas mileage. This is primarily due to the full tread on new tires, which creates more rolling resistance compared to worn tires.

As the tires wear down and the tread becomes less pronounced, the rolling resistance decreases, and your gas mileage should improve. If you’re concerned about fuel efficiency, consider low rolling resistance tires, which are designed to minimize this effect.

It's a concern of mine when I get the AWD Hybrid Lariat - with 19" rims.

My goal is to find a 17" rim that is lighter weight than the 19" OEM rims to offset the increase weight of an A/T tire.

Going up to 235 and a meatier/chunkier tread is going to chew into MPGs but hopefully I can negate any weight increase with a lighter wheel.

Anyone interested in a new set of 19" wheels and tires from a 2025 Lariat?

I'm sure there are enough hybrid vehicles in the United States that even Walmart carries tires for hybrids.
I agree with the theory that it's a new tire with more rubber that means more mass to get rolling and a little less fuel mileage.

This.


Another thing to remember also is the OEM tires when new were only 8.5/32 tread depth. Most new tires, even cheap ones are usually more than that. That will hinder the MPG even more until they wear down. A tire with Eco in the name implies low rolling resistance I thought, but compared to what at that price?

 

[Hot Runr Guy]

Not sure what the OEM Continentals are rated at, but the UTQG specs on the Montreal Eco 2 is 400 AA, which tells me its a fairly soft tire. Probably not the best for low rolling resistance.

I still have my original tires on my '22 Ecoboost AWD at 66,200 miles . I've been getting 33.4 mpg ( almost down to the wear bar) . I'm getting my new tires installed on Monday. Also a cheap set from Walmart ( Crossmark ht-225/65/17) . I'm imagining a 2mpg decrease due to the new tread at 11/32 . I'll come back here in a week or 2 to update you all.

I recently went from the (for some reason unevenly) worn Scorpions on FX4 rims to steel take-offs with stock Continental tires and went up a couple mpg. More tread on the "new" ones, and they ride nicely, too. IMO

Based on experience thus far, I would have no complaints sticking with this model of Contis for the life of the vehicle! I probably will look for similar when it's time to replace.
