Bigger tires on a MT offroad

Will bumping up tire size from 265/70/R16 to 265/75/R16 effect the power on my Taco with a Manual transmission? I can see how it would on an AT.

 

Not that I noticed.

I have noticed the minimal extra ground clearance and better grip though.

 

Technically, any change in tire diameter will affect your effective gear ratio, this applies whatever the transmission type.
Really, going from 265/70/R16 to 265/75/R16 should not be very noticeable.

 

Nope. Try to not go heavier than C load. I noticed no mpg or power loss. I did notice better looks though!

 

I doubt you will notice any difference unless you are changing to a much heavier tire. I have a 4.0 MT but I went up to a 295/70/17 and I only really notice the power loss on the highway.

 

Is your suspension stock?

 

nope not at all. Just letting you know that I don’t find the power loss that annoying. I would think that having an MT really helps

 

I figured. 3rd gen MTs have 4.30 gears stock, vs 3.90 on the auto. That definitely helps.

Off topic, how’s Prince George now days? Going to visit my sister in the beginning of august! Coming from Surrey.

 

I think I’m geared even higher than that. Probably 3.73 because I drive a sport.

PG is always great beautiful place to be this time of year and the river fishing is just starting to get good!

 

Awesome! I can’t wait to go on this road trip!

 

Mrtacoma88, looks like those are K02 tires, I like those. Those are 32" dia tires? Don't see any prob with the fit.

 

You'll be good especially since the manuals has better gearing than the autos. Also what load range tire you pick in 265/75/16 will make a big impact too.

 

I think the gear ratios are the same, but I've been wrong before.

 

Manual Tacoma axles run 4.3:1 gears versus the "taller" or "slower" 3.909:1 in the autos

 

At 60 MPH i'm at 2000 RPM on my MT... In my old Tundra AT 2000 RPM is about 70 MPH.

 

Yes sir, KO2s in 265/70/17 so 31.6”. Awesome tires and they fit great.

 

Yes, I noticed that as well right away. I would have thought 6th would give us much lower rpms at those speeds.

 

2nd gens have different gear ratios than 3rd gens.

 

Well, a taller tire could help a bit with the MT gear ratio. And I am sold on those KO2's. Thanks

 

Depends if the tire is heavy as hell or not
I went with c load duratracs because they were only 7ish pounds more than stock

here is a thread i made a while back comparing popular tire specs
