Just picked up a 1998 gen 2.5 Montero, and am looking for some advice or actual data on tire size and the effects on mileage. I like tall and skinny, so 33x10.5 is a consideration. My driving is mostly rural, and relatively flat so the taller tire and rotational mass might not be a big deal, but I am also unsure of gen 2.5 gearing. From reading other posts on the subject it sounds like 33's might be pushing it. 32x11.5 is the other option, but a wider tire has more drag- and how are the 32x11.5's on the oem wheels? not interested in aftermarket wheels. And lastly- I have a set of Montero Sport 16x7 three spoke alloys, not sure of the backspacing, but this opens up my options as well. Not planning a lift at this point, or bumpers. Trying to keep things light. Thanks

If you have the 3.5L engine, then it's 4.2x gears in the r&p.
If mileage & power are the key considerations, then just throw stock tires in an AT or MT pattern on there. The vehicle's 4x4 system is pretty reliable and capable of handling most trails and the only benefit adding bigger tires will bring is greater ground clearance.
As for mileage, all I can provide is my mileage with 35x12.5x15 BFG KM2 mileage figures which is 13-15 mpg mixed driving and while I'm no red light racer (one who runs quickly from red light to red light) I do typically have a slight Mario Andretti complex and have to control the urge to speed up when being passed LOL.
You may consider 31 10.50 or 33 10.50. While I like my 33x12.50 (got em cheap) for the stability they provide, I'll go with 33x10.50 next go around. I get 12-19mpg with a heavy foot.

That's a pretty big range, lol.
City/Highway+heavy foot= bad mileage:sombrero:
