P265/70/R16 vs LT265/75/R16

I am looking to replace my summer tires on my 2002 Tacoma TRD 4x4 (I use studded snow tires Nov 1 - March 30). I have been running Les Schwab Wild Country 265/70R16 tires in the summer.

Using the Yokohama Geolander A/T S tire for a tire size comparison
Tire size Tire Weight Tire Dia Tire Width P265/70R16 OWL 37 lbs 30.7" 8.3"
LT265/75R16 D 50 lbs 31.9" 8.3"

What effect will the heavier LT265/75R16 50 lb tires have (about 52 lbs extra weight assuming the tire weights shown above are correct) compare to the lighter 37 lb P265/70R16 tires other than gas miliage and possibly some rubbing on the frame? Does the rotation of a heavier wheel-tire have any vehicle stabilizing effect?
My reason for considering the heavier LT tire is for tire survival when driving on rocky logging roads in the Cascades of Washington State.

I have read many of the posts regarding tire sizes
Thanks Mike

 

On my 01 I haven't had a single problem with My 265/75/16's, other than losing MPGs because I went from passenger 265/70's to BFG all terrains. I haven't had any rubbing but I have a 2" leveling kit up front. And no problems with stability.
Also, 75's were $60 cheaper a tire that the 70's, couldn't tell you why.

 

I run 265/75/16 all terrains but they were put on the truck before I bough it so I cannot compare it to the stock size. My winter tires are stock sized, but I used 4wd and it's too cold to get an accurate comparison of the two. I do know I get worse mileage than what a lot of people on here report. I rub the frame at full lock as well, but my suspension is very worn out.

They are load range E tires as well. I do a ton of driving on gravel roads and old rocky mining trails and they are holding up great. Although I did notice a large chunk missing out of one of the lugs a few days ago lol.

 

So if you're talking about either a 4 ply or a 10 ply tire, both IMO should not be on a lil truck like a Tacoma that is going to be used off-road! A 6 ply tire is preferable for our trucks for off-roading (unless you plan on Xtreme off-raoding) and will be much lighter than that 10 ply! I would stay away from the 4 ply tire if you plan to drive on rocky roads or drive any trails and whatnot. Ask whoever you are going to for tires to find a more practical tire (6 ply) for your trucks needs and uses! And disregard this whole paragraph if that 75 series tire is a 6 ply! lol

I see that the tire is an 8 ply now... but still, that's a little overkill for a Tacoma.

 

I don't agree that a 10 ply tire is overkill at all. Sure, it's heavy duty but there's nothing wrong with that. I'll sure the sidewall won't flex as much offroad, but that will only matter if you offroad a ton. And fwiw, I've never had an issue with traction in any offroading I've done with my 10 ply tires. As long as you air them down properly it shouldn't be an issue.

 

No, there's nothing wrong with heavy duty, but why put all that extra weight into a tire when you don't have a heavy enough truck to use it? For what I believe this guy is looking for is a durable, yet gas friendly tire, and a 10 ply isn't the answer at all (unless he plans on hauling lots of weight or wheeling super hard)! He needs something that has a good rolling resistance (which weight plays a huge roll) and needs to be usable for off-road use, too. All I'm saying is that a 6 ply does the job for both of those needs, and isn't more than what they'll be used them for.

 

Hey Guys Many thanks for your comments and suggestions. I am leaning towards getting the 6 ply or D rated LT 265/75/R16 tires for my 2002 Toyota Tacoma. My 1999 Chev Silverado 2500 3/4 ton 4x4 pickup with a 454 cubic inch engine (gasoline) uses LT265/75/R16 tires.
It looks like going to the D rated tires will add about (4)(13) = 52 lbs. A couple of days ago I put eight 30 lbs sacks of sand (about 240 lbs) in the back of my Toyota Tacoma and it does make some difference (drove about 140 miles with that load) . So I am guessing that the extra 52 lbs of tires should easily be tolerable.

Did you get your tires? How do you like them & what did you get?

 

I've ran P265/70, LT265/75, and LLT285/75 on my tacomas. 265/75 seems to be the best compromise between a little gain in height vs. power consumption/bad mpg. I did buy a more aggressive rotor, brake pad, and installed SS brake lines to compensate for the additional weight of aftermarket rims and bigger tires.

 

On Wed May 8, 2013 I purchased 4Yokohama Geolander A/T S LT265/75R16 D tires from Discount Tires for $138 each not including Wash State sales tax etc (it was the same cost as one can see on the internet - about $687 total). I had to bend the right rear mudflap back about 2" as the larger diameter tires were rubbing that mudflap. I notice some rubbing noise when making a sharp turn - but I was not able to tell which tire was rubbing.

 

I just put some 265/75R16 Coopers on my Taco. I noticed rubbing at near full turn as well.

Get down by the tire with a flashlight if need be and look on the rear fender well for a clean spot where it was rubbing. It should be obvious. I ended up taking off the front mudflaps, cutting away the portion of the plastic well guard with a knife, pounding the pinch seam over flat, then spraying it with black rubberized undercoating to protect it from rust.

No more rubbing....except at full turn and going over a decent bump.
