Milage question for a 87 2.4 EFI?
I'm just curious what milage should I expect from a 87 EFI running stock 31in tires.
If anyone knows I would also like to know what 32"tires will do with milage and 33" tires?
I just bought a 87 for a daily driver for now, it needs tires so I'm thinking 32in at's for now. Later I will sas it and run 35's but I don't want to do allot of work to it right now.
Is someone has one with stock gears and 33's on stock rims those are the numbers I really want to know, just ball park!
Thanks!

using winter fuel (in colorado that 15% ethanol) and 31" tires on my '89 22re i get about 18-20mpg under normal (50/50 highway/city) driving. but i did an experiment for the last two tanks where i really concentrated on keeping under 1/3 throttle (that's where the EFI runs in closed loop and runs more efficiently) and over those last two tanks i got an average of 23mpg. on highway trips i have seen as high as 26mpg if i average about 65. when i have to take the poor 22re over the mountains of colorado i can expect 16mpg for highway driving.
in theory going up to 32" or 33" shouldn't affect the milage. it may be harder to turn the larger tire, but you'll go farther per turn, and everything should even out. but there are a few things that won't even out. 1)the tire will be bigger and therefore "squishier" and you'll lose energy squishing the tire. 2)the taller tire will make your truck have a slightly larger profile in the air and you'll get more drag. 3)if you don't regear, your engine will be running at a different speed for the same ground speed. the engine is tuned for the most efficeint operation at a certain rpm. if you're running out of that range you can expect milage to go down. i can't say how much of an effect you'll see but i do know from past experience that i see no difference in milage whether i have my 30" winter tires or my 31" summer tires on my truck. nor did my brother notice any difference in his nissan pickup with the stock 28" or the new 31"

I get 18-22 with 33s and geared with 4.88s. My friend has 31s and 4.56s and gets the same. I would think that you will also get around 20-22 if it is properly tuned and running well.

I guess now it just depends on what I find the best deal on 32's or 33's
