Any reasons not to go with 265/75/16?

lucky lucky man!!

 

I was lucky here.

 

I remembered going through a forest and hearing a big slammed! My right side mirror took a hard hit against a tree LOL! good thing it wasn't the opposite way!

 

I had the SL 265/75/16 ultraterrains installed this week on my TRD Off Road DCSB 6sp auto and I love them. I was still running the stock goodyears. I almost bought the duratracs but wanted the lightest tire I could get. The ultraterrains look fantastic on the truck. I can't find anything negative to say about them other than Discount put too much air in them. I need to chalk test them to get the right pressure. They did not make the truck feel slower at all. If anything, I am running a lower RPM to stay at the speed limit. According to my phone's GPS through Google and Waze, I am showing 3mph slower on the speedometer than I'm actually going.

 

There are 2 different Goodyear Kevlars in that size. The stockers are only 35lbs.

My initial tire upgrade was Duratracs in 265/75/16 at 45 lbs a tire. The truck did feel a hair slower. After a day or 2 I just got used to it and the truck performed perfectly fine in my opinion. A year later I went to a 265/75/16 Cooper M+S at 39lbs a tire. I didn't notice any performance gain at all from the lighter tire. Which leads me to believe the larger diameter had a greater effect than the extra weigh. Now if you jumped up to a 50+ lb E rated tire I'm guessing the weight will start to have more of an effect.

 

I replaced my tires right after I bought the truck as it needed them anyways. I went with 265/75/16s (original size is 265/70/16s) mainly to make the speedo accurate. Of course I went with KO2s because that always seemed like the go to tire. Paid no attention to the E rating (which I don't need) or the 54lb weight! Now that I've added 130lbs to the front in the form of a bumper and winch, my next tires will be lighter. As it's now pretty sluggish feeling compared to before. But you make a good point. I think I'm going back to the stock size and an SL tire then the KO2s wear out. Probably the Ultraterrains or Falkens.

 

Last weekend I switched my stock steel wheels and tires on my 2018 Access cab with 4 cyl motor.
Found a guy who took the factory alloy TRD wheels/tires off his truck at only 400 miles from purchase to put on monster wheels/ tires and a lift kit.
Had them sitting in his garage since 2018.
My original tires are Hankook 245 75R 16. The tires on the new TRD wheels are Good Year Wrangler 265 70R 16 and to be honest I can't tell much of a difference in power but do feel like the truck went up 2" in height.
Always take the same route to work everyday and when I shut off the motor it says 7.7 miles but today it read 7.5 miles.
I really like the look of the bigger tires and new TRD rims over the steel wheels I did have.
Here is a Pic from last Sunday.

 

Well yes the gas mileage would be worse but at least on the 2nd gens it makes you MPH right on the bullseye. I think Toyota went with a smaller tire as stock to "boost" they're MPG #'s ( Well with the 4.0 motor that is )

 

That's not really logical. It's not so much the diameter of tire as much as weight and tread width that helps or hurts mpg. Whether people here like it or not most owners care about mpg. As far as speedo accuracy? It is not as important as odometer accuracy and they are not the same.

 

Hate to break the news to you but the new wheels and tires are almost the exact same size. You also did not get 2” of lift from them. You would need a 4” bigger tire to give your truck 2” in height.

 

265/70/16's are the same overall diameter and height as 245/75/16's. They are just 20mm wider. That is an optional factory size on many Tacoma's. A 265/75/16 is about 20mm wider and about 1" taller than stock and I think a good compromise. That used to be the factory size used by Nissan on their Frontier and X-terria before they dropped down to 265/70/16.

I've been using 265/75/16's for a while, and for several reasons. The size is just big enough to look better without sacrificing performance. I still get the same fuel mileage even with E rated tires and there is no loss of performance. 265/75/16 is a much more common tire and they cost less than the smaller 265/70/16.

Yes, it does effectively change your axle raio, but in this case not enough to hurt. My truck with the 4.0 V6 has 3.73 gears, with the new tires I'm effectively now at 3.66. A 4 cyl starts with 4.10 gears, changing to a 1" taller tire will effectively change it to 3.95. If you go to a tire large enough to effectively change the gear ratio so that it falls much under 3.50 then you'll struggle for power The most common axle ratio in full size Chevy trucks is 3.43, Ford uses 3.55 in most of their V8's. The 3.5 turbos mostly have 3.31 gears.

Going much bigger than 265/75/16 means you need to also start modifying other things on the truck to make them fit as well as needing to regear the axles to get back power.

 

265-75x16 is all the tire the average Joe needs on his Tacoma......LT of course

As stated...go bigger....more mods needed to compensate for the bigger tire/wheel

 

Yeah, well I can't argue with that.
Must have just been my perceived perception of the change. Obviously I never measured anything. Clearly the width was the biggest change.
No question that 0.1" increase in tire height has affected my odometer to about 2 tenths of a mile every 7.7 miles.

 

funny I have 245/75/16's on my 4 banger also and whenever I see 265/70/16s on TRD models they always look so much bigger. Even though by the numbers its not any taller, just wider.

 

add to the mix the ever growing popularity of skinny's . . . 255's

 

His stock tires were 245s.

 

I went from stock (2015 v6 4w) to the Cooper AT 265/75/16 e load. A couple of inches bigger diameter and 10# heavier. I definitely noted it was more sluggish on take off... you can overcome that a bit by driving in 4th in stop and go. I lost about 2mpg with the change. I later regeared, which minimal impact on my new lower mileage, but was no longer sluggish on takeoff.
If I had to do over I would have probably kept a little closer to stock diameter and not regeared, as I do a lot of towing. I now have Cooper AT 235/85/16 (same diameter, but thinner). I still get same basic mileage, was hoping for a small boost.

 

You almost scraped the only rock on the beach.

 

exactly my thinking, even though i wish there were many more non e-rated lt tires.

 

OP, what gear ratio are you running? I have the 2.7 and run 31's(265-70r16) with 4.30 gears and pretty happy with it. I feel that with the 4.30 I could go up to 32's and be OK. If you are geared higher than that, I'd stick with the smaller tire. Falken AT3W are fantastic.
