I own an '09 Pro 4X OEM tire size 265/75/16. O.D. 31.70"
My original Frontier was an '06 LE with a separate set of rims and winter tires for a winter setup sized 265/70/16 O.D. 30.60"
Since I bought the '09, I've used the 265/70 setup for the winter. I only noticed the difference in size/diameter until this Fall.
I've used this setup for the last 5 winters.
Question: Other than the speedo and odometer reading high, does this difference in diameter affect any of my truck's systems ABS, traction control, etc in a detrimental way?
I've never noticed any side effects.
I'm in the market for new winter tires. the 265/70s are cheaper and have more selection than the 265/75's hence the question.
What do you think?

I don't know if this is an answer 4U but I didn't notice any ill effects after 40k other than they're about a 1/2" shorter than a 75 and my mpg dropped about 1mpg going to the 75 but my speedo an mph actually matched my GPS now since going from my oe 70 series. I have 10' SE that came with the 265/70/16 but I find it strange though that your finding better selection with 70series cause when I went looking for A/T tires IDK about winter tires but I felt I found a lot better pricing an had more choices in the 75series than the 70 though maybe region has something to do with it also IDK I see your in Canada but everyone here in Texas has at least 3 pickups to every 1 car in their driveways here

Btw IDK if this helps you either or if your looking for studs which I don't miss having to do anymore lol but I went with the Falken AT3's they're severe snow rated the little snowflake with mountain symbol I like them quiet on road and didn't need 4wd as much going down the the mud roads out here in Texas they're pretty cheap also an discount has $100 off 400 on eBay right now.

I'll be replacing in a day or 2 and I got 40k on mine with [email protected]/32([email protected])an my new spare [email protected]/32 an [email protected]/32 I would of easily gotten the 50k but just got a hole in 1 day b4 yesterday yeah no patchin this one it's a half an inch hole

No difference in any of those systems, I went up to the 75 series tires on my last truck and no issues on that or my Pathfinder.

I would say no bad effects. Car manufacturers will produce speedo sensors for certain transmissions and they will be set for the highest usage. As in the pro 4X with the taller tires. They’re not going to remake different ones for each vehicle with different size tires. For the same transmissions. So my 17 has the two 265-70s And my speedometer is off 3 miles an hour at 60 mph. So when I Royer these tires out I am going up to the 75’s. The only affect it really will have is in the long term you will be adding more mileage to the truck then is actually on the odometer.
