FUEL ECONOMY - 5 Reasons Your Wheels KILL MPG

In this video we discuss 5 reasons why your aftermarket or performance wheels KILL MPG on your vehicle. The reasons are often overlooked and there are other factors but these are the 5 most important reasons fuel mileage is affected by simply changing the wheels.

The diameter of the wheel is a completely different issue which affects gear ratios but these 5 are important factors to consider when choosing your next wheels.

I took my wide 20 inch wheels off my silverado and put the stock ones back on. A really big difference on gas and ride. I went from 16 mpg on the freeway to 26 mpg. Keeping the stock ones on and selling my 20.

Ahhh yes thank you, I'm off to swap my wheels on my Volvo c30 to bicycle wheels

I agree. Keeping my 18 sport stock wheels. looks good already and plus I know I wont have issues in the future with bearings, gas mileage, axle issues, etc.

I know this is a little random-off topic, but I just want to say I really appreciate all your videos. I've watched a lot of guide videos and your videos are by far some of the best I've seen. The way you explain it as you do it instead of just doing a voice over style clip is really nice. Keep doing what you're doing and releasing new content and I'll continue to watch. Thanks for everything!

Great info... I keep the same size tires on my truck except slightly more narrow usually a 70 series to optimize fuel economy.

[DJArturoMuela]

Clear as water, thanks man ! You made a great detailed explanation of weight, air resistance and commodity caused by bigger tires 🙂👍

Would really like to see real world MPG test of stock vehicle and then another stock but with lift kits and 35’s and do a highway test. That would be a good video for future use. Love your channel btw.

Yeah. I have a 2017 Ram, SLT with 22x12 rim and 35” M/T tires and my MPG is right around 11 miles, but even when it was stock, it was right about 15. All in all, it sucks, but I love the set up.

I have a 4x4 Lonestar and went from the factory Goodyears to Nitto 35x11.5R20 Ridge Grapplers on a Bilstein level with factory wheels. I’m getting real world MPGs of 14.7 in city and 17.4 at 75 MPH on highway. Totally worth it for the look. BTW, adding the K&N CAI and a Borla ProXS muffler did nothing to effect MPGs but it sounds cool as hell!

[anthonyflorez]

Yea I got the lifted truck with muds and mpg sucks but I love how it feels and looks!

1 inch smaller radius tires on my 95 ford increased gas mileage 3 mpg compared to stock. The speedometer read 5mph faster going around 60mph. Put on tons of miles never had any issues, it ran great.

I had aftermarket wheels on my car and I switched to OEM wheels instead for better fuel economy thanks 🙏 for vídeo very helpful.

[myktmify]

Thanks for the explanation! Very detailed!

[valiantredneck]

Great tips as usual. Thank you. ‘Course I’ve never thought my ‘14 Ram as being aerodynamic. All the best.🇨🇦

Thats why I did some number crunching when I swapped from the OEM 16s to the RT 17s on my Dakota. Wanted a change but not alot to upset the Apple Cart.

16x8 was 28lb and 245/70-16 (29.5") Wranglers weighed 32lbs (60lb total) vs 17x9 at 32lb, and the 255/50-17 (27") Hankooks at 32lbs (64 total) 9.6 to a 10.0 wide tire... measured IRL with a tape measure, 28.5 to a 27, the Hankooks ran to size, Goodyears were 1" smaller than they should have been in diameter but it was lowered 2" in the front and 3.5" rear at the same time as the wheel/tire swap. I still had roughly a 1 degree of rake vs the 3.5 it had before at stock height.

To compare: The Dakota RTs came 255/55 17 stock on those 32lb wheels and the tires you can get weigh 32lbs too, but a 5.9L 4spd auto and 3.92 gear vs mine with the 4.7L 5spd auto and 3.55s. I was getting an average of 13.5mpg (80% city driving) before, so far the three tanks Ive ran through it, roughly seeing between 13.2 to 14.1mpg now same driving style/pattern. Tons of variables, I'm not going to drive it like a sedated nun like they do for MPG testing. Traffic changes, city vs highway driving %, fuel quality, weather... tons of variables.

Absolutely 1million % correct also i would add is lifting a truck or putting bigger tires it puts a strain on the transmission and as well bigger tires can throw off the speedometer

[jeffwood]

Larger tires on my F-350 dually increased my in town mileage from 14.9 to 16.1, highway 15.7 to 17.6

[johnbowhunter]

27mpg highway with a hemi?...WOW that’s very good!

[superwarrior]

Thank you for the info. Saves me a headache and

[shootandcatchemall]

Yeah I got a 2017 silverado... 17 avg mpg when stock, put on level kit, 2 inch spacers, wider rims and mudding tires, dropped my mpg to 13 🤕
