tires for 99 4Runner?
What tire would be recommended for a 99 4Runner SR5 2WD that will be used strictly for daily city driving, never any off-road? Want something quiet and also good in rain. Door pillar says 225 75 R15 but I've seen posts recommending a larger tire and saying that some of the 99's came with larger tires. It has aftermarket 15" wheels on it.

Best All Around Tire Size for 1996 SR5 4Runner
Just recently purchased a 96 SR5 and have been slowly building it up form stock. The truck needed tires badly so I went for a set of used rims and tires off a '19 4 Runner. 265/70/17's
About to upgrade my suspension to the 5100/OME 2" lift. Would like to put the optimal all purpose tire on it. Any recommendations? Exp. Overland mentioned a 235/85/16 for their build. I just want what would be best for the Swiss army of vehicles, the 4runner. Was thinking 265/70/17 BFG KO2's or 245/75/17 KO2's.
Im planning to drive the vehicle to Costa Rica come this December. So trying to get ready for that adventure. I welcome anyone to join!
Thanks!

Does that mean all the 4runners sold with the optional 16" wheels had speedometers that were off straight from the factory? Or maybe Toyota had a different speedo setup for each of the two wheel sizes?
If I'm understanding correctly, the 15" rims translated to a 28" wheel while the 16" would be almost a 31" which is a fairly sizeable difference IMO.

This will be a daily driver.

my sticker on the door panel says P225/75R15, even though it came with p265/70r16 rims and tires. my original window sticker lists the larger rims and tires as part of an optional equipment package. (upgrade value package #4)
i could be wrong, but i dont think the dealer changed the rims and tires because there were too many other things in the option package that i dont think the dealer would have fooled with-

My door says 225, but my window sticker says 265. Both the VINs match, so IDK whats going on there. I wouldn't be surprised if dealers did upgrade wheels, but I doubt it was widespread. My theory is that if your 4runner trim didn't come standard with upgraded wheels then you got a 225 sticker regardless of options.
Okay upon further checking I can only find limited models with the 265 tire on the door sticker.

That’s my hypothesis too. Basically, models that only came with the 265 tire got that listed on the door sticker but for models that came with either size based on option packages, my guess is that those all had the 225 size listed on the sticker.
The reason that I’m even worried about it is that I’m trying to figure out how far off my speedometer is with my 33” tires since I don’t know if the speedo was setup for 225 tires (door sticker) or 265 (what I think was equipped at the time of purchase).

1. As with with the axle ratio code numbers, the door sticker may not be accurate on the wheel/tire size. One of the colorful quirks of Toyota.
2. Find a friend that has a hand held GPS receiver (or smartphone with GPS app) that shows speed in MPH, go for a drive on the highway and check against the GPS. GPS speed isn't accurate at slow speeds, so go 30MPH or above. 60MPH is fine.

Thanks! My wife and I both installed the Speedometer app on our iphones and took the 4runner onto the freeway. The results were really strange though because both phones showed 3 mph faster than the 4runner's speedo at all speeds ranging from 40-80 mph. I thought I would be further off with 285/75R/16 tires and that the difference would increase as the speed increased. Perhaps 35 psi is not enough for my tires so they're underinflated reducing their effective radius?

The difference should increase as the speed increases. Your actual speed should be ~7% higher than what your speedometer reads based on the tire size assuming your speedometer is calibrated for a 265/70/R16. If your speedometer was calibrated for 225/75/R15, then your actual speed would be ~16% higher than what your speedometer reads.

My SX 99’ has 4.30 axles and the speedo is dead on with 265/75. It says 15” wheels on the doors.

Yeah, that's what I expected too and was surprised that the GPS reading was off from the speedo by the same amount regardless of speed.
My only guess is that 35 psi is not enough for the new tires to be fully inflated so they are currently very close to the stock size and that the 3mph difference is just a fixed variance between GPS and speedo.
The freeway I tested it on does have some curves and hills so maybe I'll give it another test next time I'm on a straight and flat section.

It's impossible to know if 35psi is too low for your tires without knowing what you are running, and how much extra weight you may be carrying, and even then there's some personal preference involved in that. I know that for me 35psi would actually be higher than I'd want to run.
Either way, I don't believe you actually have a fixed difference between the speedometer and GPS, you likely just can't read the speedometer accurately enough to see the change. If you did have a fixed difference, it wouldn't be due to tire pressure because the tire pressure impacts the diameter which means whatever affect it has will be tied to speed just like changing the actual tire size.

I run 45psi on 265/75/16 mud terrains and have no problem climbing mountain highways or driving for hours at Interstate speeds with 4.30 gears. As soon as I hit dirt I'm at 18-20psi. I popped out of the desert on my last trip to get supplies and forgot to air up and drove 40 miles at 70mph at 20psi - I realized my mistake as soon as I absorbed a speed bump in the liquor store lot and immediately checked my sidewalls - not hot at all, so no harm done! But anyway - I have a dumb question: where does my Ultra Gauge pull the MPH data from? The ECU, I suppose, but what is the equation/sources? It's always a couple mph off the the dash "gauge". Slower, if memory serves.....
Edit - I added the Trans Temp reading to the gauge but I do not recall doing any odometer/mph calibrating.
