What’s your mpg with bigger tires??

2020 Sport S
3.73 gears
285/75/r17 Toyo Open Country AT3 on stock rims
no lift

I am getting 16-17 mpg with 100% city driving right now, much of it idling in traffic. I need a short vacation to test the highway mileage!

I think it's prudent to adjust the tire size in order to keep the odometer and speedometer accurate, if nothing else.

I was getting a bit of knocking on 87 octane and moved to 93 for now. I am not sure if the heavier tires aren't contributing to it. Surely not a cost effective way to drive, but I knew that going in.

Don't mean to steer off-topic but how much of a difference/improvement have y'all with Tazers seen when going up to 35s? Trying to decide if it's worth it. I didn't seem to notice a major difference going 33s>35s, maybe half a mpg and can't really notice a power difference, but am curious if people think a tazer is worthwhile.

I already had a Tazer prior to my lift and new tires. My 2" AEV lift came wit a ProCal Snap that I never used. I'll send it to you for $75. PM me if you're interested.

11.5"x35" Toyo OpenCountry AT3 @ 33psi
17x8 KMC Roswells
350lbs rack and RTT
25.1 on last fill-up
Speedo re-calibrated via ProCal during AEV 2" spacer lift

For awhile is was right around 23mpg but it seems to be going up due to me settling down on the pedal.

What gear ratio do you have?

I went from the stock 255/75-17 KM2s to 285/70-17 Kenda Klever AT2s. Not a drastic difference in size but I actually gained a few mpg. Probably due to the less aggressive tread pattern.

3.6l
3.73 gears
19-20mg around town

What gear ratio do you have?

Willys diesel has the 3.73.
