OFF ROAD VS STREET TIRE MILEAGE

Thank you for having me. Has anyone changed their tires from off road pkg to street package, and what kind of gas mileage did it change to? I just picked up my 2021 Tundra Double Cab TSS off road package. Being I am going to be primarily using it on the street until winter in the North Country NY (I currently live near San Antonio, Tx), I am wondering if it is worth spending the money on all season / non aggressive.
I will say, I should have bought a tundra years ago. As a retired auto insurance adjuster, Toyota Tundra has proven to be the toughest and safest truck out there.

 

I am damn happy to hear about the Tundra’s toughness coming from someone in your field.

Truthfully, changing your driving habits will net the best gas mileage. Starting slow off the line and not going over 70 is what I find works best. And using cruise control. Keep the air pressure higher than the door plague suggests.

The Michelin AT2 are one of the mildest non aggressive tires on the all terrain market. You will see a small bump in MPGs with a lighter tire such as the Michelin Defender LTX. I just don’t think it would be worth it to change the tires until what you have are worn out. A BfGoodrich KO2 or something similar (heavy and aggressive) would be worth changing tires for IMHO...

 

Welcome from North Texas!

Maybe look for some 20" takeoffs.

 

Welcome.

You won't see much of a difference in MPGs if the tires are both the same standard diameter, you probably will notice a little bump if you switch from an oversize tire to a standard size. I run 18" Michelin A/T2s now and M/S2s when it's warm/hot, both have the same exterior diameter.

 

The Off Road tires are pretty mild already, I doubt you would see enough difference to justify the cost.

 

If the tires are the same size, just the weight will really affect the mpg. I live in the “North Country” and have nitto ridge grapplers. They are good for packed snow but horrible on ice. If you are worried then you could get some good winter tires that are the same size as you stock tires with no big change in mpg. BFG and Goodyear also have some 3 peak ATs, but they are heavier than stock.

The problem though isn’t the driving, it’s the stopping. The tundra is a heavy truck and doesn’t like to stop on ice and there usually is ice under the snow. I drive in S3 or S4 on snow, keep speed down relative to conditions, and give myself lots of space to stop. 4wd will get you going again.

As far as being worth the money, wait until you get here and try out your stock tires. Just drive as conditions dictate.

 

Im guessing you have bfg ko2’s with the tss package?

i recently ran E rated bfg’s and then swapped them for a set of oem Michelins. My mpg is maybe 1 higher on highway trips, but identical in the city
