p265/65r17 vs p265/70r17

Hi taco lovers. I have a 2020 DCLB Sport with 35k miles with stock Toyo A30 Open Country p265/65r17 rotated every 5k miles.. I'll be needing a new set of tires before winter and considering going up to a 70 profile tire. Mileage is important since we drive 300 miles each way to Maine all winter long from Cape Cod. While on the Cape, we off-road on a beach deflated to 18 lbs.

So what are the drawbacks from the larger p265/70r17 tires ? Any MPG decrease ? I'm leaning towards Yokohama Geolandar A/T G015. Tax-free weekend coming up here in MA.

 

no significant drawbacks at all. unless you run factory mudflaps, in which case you may get a little rubbing on them. no noticeable mileage hit.

 

Thanks for the reply su.b.rat. I read hours of posts here also.

 

I went from a 265/70/16 to a 265/75/16 and noticed no mpg difference. If it’s there it’s so little it’s unnoticeable. Did have to remove stock mudflaps which i was going to do anyways.

 

Just spoke with the tire folks. They mentioned the ABS is set for 65 profile tires and will act differently with taller 70 profile tires. He's seen codes posted due to the different size tires. Earlier cars didn't have all the computer monitoring like newer cars. His 20 years of tires experience recommends staying with the original size.

Was there smoke being blown through the phone ?

 

i would probable talk to some one else..

Been running Pirelli Scorpion all terrain plus 265/70R-17 for over a year on my sport.
Draw backs- a little slower on the pedal response, Bigger Dia
The speedometer is a little off- around 2MPH at 70
If you get E rated there heavy and you will notice them IE "BFG KO2"

Pro - the truck looks a little better with a bigger tires.
you are actually putting more miles on the truck than what the odometer is saying in reality. (higher resale)

Theres more that others will add I'm sure
(PS: another tire thread)

 

Yes.

I run 265-70 r17s and have for years. Many people on this forum run that size and a lot larger.

Never have heard, experienced, or read of tire size throwing an error code on the Tacoma. Some people had TSS calibration issues after running both a larger tire and a lift due to the grille sensor facing a direction it didn't expect, but that was a very rare occurrence, and it's easily fixed if it does happen.

 

Just got 265/75/16 in place of 245/75/16 on stock 2020 SR
No rubbing no issues so far other then the loss in MPG
Went from around 20 plus to 18 plus in normal driving
Set them in OEM TRD wheels, Toyo OC 3. Nice tires, good warranty and wear out
No or low road Noise increase. Nice ride and good look
