Hello everybody, I am a Northern CA local living in LA with a 1989 4runner 3.0 v6 5speed. I am hoping to learn how to squeeze what i can out of the engine and drive train to get as much MPG as it can manage as i would like to make the truck a road trip vehicle. I already drive it easy, mostly the speed of traffic and rarely reving past 2k on accelerations (you should see how frustrated drivers are behind me at stoplights.)

The truck is about to turn 250,000, but take pretty good care of the engine and drive train with routine maintenance, (fluids, plugs, wires, belts, and lube of suspension and drive train), But everything is bone stock. It is my daily driver and does mostly highway. I do use it to haul stuff often, including a hitch mount motorcycle carrier.

So initial questions i have, currently the truck is running on 31 inch BFG AT's. I do use the truck occasionally for offroad/snow use which those tires excel at, but i am thinking of having two sets or rims, one set for onroad/snow and one set for offroad. I figure if i make the switch i can find a set of the stock Toyota alloys that would have come on the nicer trucks and have the option to run smaller tires. So, do you guys recommend running the stock 225/75/r15 that it says on the door or the larger tires. The tires i am looking at are the Firestone Destination AT's, as reviews say they are very good for AT and truck tires, and they are less aggressive than the BFG's

Something that is a bit concerning is at 70mph which is normal LA freeway speed the engine is turning 3k rpm, and i know these engines are semi famous for not liking to rev too much higher than that. With the age of the truck id like to not blow the engine just by trying to not get run down in LA freeways.

My other hobbies i mean vehicles include a 1977 yamaha xs360 , and a 1967 beetle (modded to use as much gas as possible....) But hey i came here to focus on the daily driver.
