hey im debating weather to go with 31" or 33" tires on my truck im wondering what would i expect for a fuel difference with eack i do about 120km (50-60 miles) a day mostly highway. my trucks a 91 ka24e 5speed kingcab with 235's now ...... the truck will have a 3" SL as well

maybe a couple mpgs... the lift and 31s look great on hardbodys, and are well worth the minimal gas mileage loss

31s fit without a lift.

i know that but i want the added ground clearence i just want to know how much of a gas milage difference people noticed going from 31's to 33's

i didnt notice any major decrease when i put on 33's. that may be due to me not wanting to notice it, thanks to how dismal it allready was.

15mpg with 31's on the v6. I get about 20mpg with the 2wd and 235's. I would not go higher than 235 with the ka24.

I know i don't have a HB but.... my WD21 is averaging a little over 18MPG on 35's w/ 4.88s

but in your situation... i would mostlikely say 31's but do you know what gears you have?

What about 32 and a lift any rubbing issues. 15x8 4 1/2 back spce. ??

Any tire bigger than 31" you will have rubbing issues.

i'll check the gears next time im at the shop i was gonna go with 33 10.5's not 12.50 so rubbing shouldn't be as bad and im not scared of my saw-zall lol but if i have to re-ger for 33's screw that

ive got the 4.3 gears with 33's. it does perfectly fine. ive got the V6 though, not sure what you have

Edit: you have 4 banger..... people still run 33's with stock gearing with that engine, just dont expect to beat any land speed reacords or be in the fast lane going uphill!

dont forget about b r a k i n g......

i have 33s 12.50 with a 3 inch lift on my 87 v6 4x4 and it did not make a noticeable difference on gas but i came from 31s.

I have a 97 with the ka24 sittin on 31 bf a/t. the only problem I have with the tires are that I can't turn the wheel all the way, it rubs, but I got used to it and it bearly happen anymore. 17 mpg until the swirl valve went out know 15.6. changed valve on new tank i'll let you know what I get now.

I had 33 x 10.50's on a regular cab 4x4 4cyl and stock 4.3 gears with a 3 inch body lift. I don't know if I ever checked my mileage afterwards due to the speedo and odo off. I think I had mine figured at 12% off. The major thing I noticed was that 5th gear became worthless on both hills and to some degree on flat land. In some situations I started to use 3rd gear to climb hills that in the past I would use 4th. Stopping increased a little but you could still stop. I think it is all about what you like the looks of. Regearing would have helped but not for the cost
