Tire Size on 4 banger

I'm pulling about 18-19 as well in my 4x4 with the 265/75-16 tires. Best highway so far was 22 with this setup. I did my lift and tires at 500 miles on the truck so I don't have a solid stock baseline.

I don't drive much true city though. More rural and suburban driving so I'm sure real city stop and go would be worse.

 

18-19 still isn't bad!! Which lift you put on it?

 

Right now just 5100s on stock coils up front at 1.75 and 5100s rear with Wheeler's 3 leaf AAL.

1.75" up front and 2" in rear, measured.

I'll be upgrading to 884X coils and Ride Rite bags in the rear and should end up around 2.25-2.5" front and ??? rear.

I am running 265/70-17 BFG Rugged Terrains on my base model 4 cyl 5 spd 4x4 stock ride height. Get slight rubbing upfront and def noticed a difference in acceleration, mpg and having to downshift more often. But I knew that buying them and the trade off was worth it. A lot more capable offroad, better ride height. MPG went from 21 to 19 average.

 

Kind of. For non metric tires you're correct. a 31x10.50 is 31" tall, 10.5" wide, 33x12.5 is 33" and 12.5" (more or less since tire makers are silly). Very simple. Metric tires, it's aspect ratio and I use the calculator

 

I'm running 285-75-16 General Grabber ATII's. Mileage is averaging 18 and my truck weighs in @ 3,600 lbs. I have an auto trans but I did re-gear to 5.29's. Performance is better than stock in that I originally had 265-70-16's and 4.30 gears. That combo made my truck a slug.
As for rubbing, it did at full lock but I welded a small 1/2" spacer behind the LBJ on each side... issue resolved. Also, I'm running the factory spare wheel on all 4 corners. That helped up front to achieve enough space from the Total Chaos Uni-ball.

Hope this helps you.

 

Thanks man! Do you have a lift on your truck?

 

I have extended travel ICON co's and Deaver 8 pack leafs. No BL, spacers or diff-drop. With the 285-75-16's (32.8"), it sits right where I like it.
