Tires too heavy?

Found a really good deal on some Michelin Agilis lt245/75/r16 tires for my truck. They are e rated. I know this is overkill but they look cool, and ride ok. My question is are they too heavy for stock gearing? According to the specs they weigh 45.3 lbs. I know some of you run 33s and 35s so I think I’m fine. Would just like to hear from someone else running LT e rated in stock size for peace of mind.

 

those are almost identical diameter and weight of the stock tire. You’ll be fine.

 

you'll be fine.

 

Are you sure you got the 245 right? That’s a skinny tire. Now if you’re talking 285/75/16 that’s a whole nother story. You’ll be fine with weight, but you’ll have 33” (ish) tires to deal with.

 

Personally, I would never use load range E tires on a Tacoma, then again, I have never driven the 3rd gen Tacoma. I would never have put them on my 2nd gen. It is all preference, if you like the "truck" feel, then you will likely be happy with them.

 

Yes I’m sure they’re 245. They’re stock size just more treaded and e rated. They look good. Was just a little worried about weight, but you all seem to think it’s fine. Thanks again. I’ll stop worrying.

 

Beloved here Wildpeaks are almost 50 lbs in this size and the load rating.
I'm shopping around and thinking to stay with the same size and below 40 lbs if possible.
245/75/16 wildpeaks at3w 6 ply are $106 on Amazon at the moment

 

I've been using load range E general grabbers at2's for a little over 20k miles. I'm sure my gas mileage took a hit, but I haven't had any issues with the truck, or any noticeable loss in power. E range may be overkill, but I like knowing that I can drive over pretty much anything without getting a puncture.

 

Load D or C in ridgegrappler or duratrac is the perfect balance of these concerns IMO

 

I go between E-Rated snow tires and C-Rated all terrains in the same outer diameter. There is about 12lbs difference per corner and it is noticeable in acceleration and MPGs.

 

I have e-rated KO2s right now. I just got them. I think made a Mistake. Pretty sure I can’t return them.


Makes a big difference in mpg and power.

 

You could easily take them off and sell them. Alot of bros love and run those

 

Went to a 265 75 16 SL wildpeak. Mpg dropped a few but power feels the same

 

I bought a set of Cooper AT3 4S - 265-75/16's to replace my stock 245's over a year ago and love them, 44 lbs each and no problems with them at all, run great in dry, rain and snow conditions..put them on my factory SR5 wheels..

 

There are no downsides to an E rated tire. There are downsides to going to larger tires and tires with more aggressive tread patterns. Most of the popular tires in larger sizes and aggressive treads are only available in E rated tires. People buy them and blame the loss of performance and fuel mileage on the heavier E rated tire when the real problem is elsewhere.

The taller tire effectively changes your axle ratio. A lot depends on the factory axle ratio. Most Tacoma's have 3.73 gears which is already lower than most trucks. Many other trucks come with 3.55, 3.42, 3.31, and some as high as 3.08. Those trucks suffer terribly from bigger tires. Going to a 1" taller tire on most Tacoma's changes your axle ratio to around 3.6 which is still lower than most trucks on the road. Any loss of power is hard to notice. Go to a tire 2-4" taller than factory and you'll need to re-gear, or live with poor performance.

Wider tires, tires under inflated, and tires with aggressive tread have much greater rolling resistance which will rob power as well as emptying your gas tank sooner. It doesn't matter if they are a 55 lb E rated tire or a 40 lb P rated tire. A narrower tire, with a street tread, or mild All Terrain tread, properly inflated rolls easier, and doesn't hurt fuel mileage. It doesn't matter if it is a 55 lb E rated tire or a 40 lb P rated tire. Stay with an AT tire in 245/75/16, 265/75/16, 265/70/16, or 255/85/16 and you won't have any issues on a Tacoma, even if they are E rated.

The air pressure recommended on the sticker on the drivers door will no longer apply once you go to E rated tires Neither will the number stamped on the tire. You'll have to experiment, but once you get the air pressure on the tires figured out E rated tires ride just fine. You're not running them on a 3/4 ton truck with a 10,000 lb GVWR so you don't need 50-80 PSI in them.

I have E rated tires on both my 2007 Tacoma and 2014 F150. They both get exactly the same fuel mileage as before.

The only downside is initial cost. But over the last 40 years I've damaged too many P rated tires driving on dirt or gravel Forest Service type roads of on farm roads. I've found it is cheaper in the long run to just buy a tougher tire than buying a light duty tire and have to start replacing them before they wear out.

 

You have good points, but it is untruthful to say a heavier tire will not affect MPGs. That’s just plain physics. Rolling mass is an important factor in fuel economy, especially in stop-and-go traffic, and the people, myself included, who noticed a drop from heavier tires in the same size overall are not imagining things.

 

Say what? The downside is the added unsprung weight and the harsher ride. Those are two pretty big downsides. I realize in theory that 10-15 lbs extra per tire doesn't sound like much and if it were sprung weight, it really doesn't, but unsprung weight and rotational weight are much different. The simplest example is just look what happens when you tack on a 1/4oz to a wheel.

 

I run E-rated 245/75 R17 Cooper Discoverer ATs. Yes, they are heavier. Yes, MPG and power drop a bit. But I have a camper on my truck and I drive a lot of 4x4 Forest Service roads, and I wouldn't look back on tire choice. Peace of mind is worth a lot.

Even when I don't have the camper installed, I am still stoked on these tires. Ride quality does suffer a bit, but I don't care about that personally.

E-rated is unnecessary if you're only ever on pavement or tame gravel - but if you're off road at all, something with a heavier sidewall just makes sense.

 

i have 265 75 16 ko2s e range, and the power drop and mpg was pretty big, ive gotten used to it though.

i had a hemi ram and when I put bigger tires on it I could feel some powerloss too. just the way things go with bigger heavier tires.

 

Load range E 37's, stock 3.73 gear, rides fantastic - rides better than stock. 7 1/2% grade 0-60 2nd gen DCLB
