265/70/17 vs 275/70/17

Forgive me if this is repetitive. I tried searching but couldn't find a clear answer. I just lifted/level my '17 trd DCSB with 5100/887 in the front and deaver AAL in the rear. I ended up with a 2" lift. My dilemma now is what size tire to mount on 17" Method NV. Im debating between 265/70/17 C KO2 or 275/70/17 C Cooper AT3.

I read the KO2 in 275/70/17 are E loaded tires and can effect performance. Does anyone know if a C rated tire in 275/70/17 would have the same negative effect? I was going to go with a 265/70/17 KO2 but if I could go bigger to a 275 without any negative effect, I would do so.

Thanks for any input

 

What have you read regarding E loaded tires impacting performance? They're just heavier and likely will have a bit harsher ride, that's all as far as I know.

 

Performance is affected by weight. Look at the manufacturers website and see the difference. The heavier it is, the more it'll impact your MPG as well as make it more sluggish. You'll also need to consider rubbing. You'll rub less, but still rub.

If it were me, I'd go with the 275 because the bigger the better! Then just cut stuff out of the way as it hits. It's only plastic.

 

All I've read from Tacomaworld is that it's heavier, affects mpg, and it feels like the truck is hunting for gears sometimes.

 

Yeah I was thinking about going 275 as well but would a C loaded tire in 275/70/17 be better in mpg and performance? Seems like a dumb question but I'm asking anyways

 

C is the best load for our truck IMO. D or E is way overkill. To answer your question, yes. A C load would be better than an E in terms of MPG and performance. It'll still decrease a little, but not as much. I had load E's on mine and it was still fine. I got 15 mpg and the acceleration wasn't hurt TOO bad.

 

Thanks for your answer. Guess I'll go with the 275/70/17

 

You'll love it. Give me a minute to dig up a side by side comparison of a 265 and a 275

 

My tacoma has 265/70r17 and the 4runner has 275/70r17. Same amounts of lift.

 

Thanks for the pictures! Hard to tell the difference in size between the two. The 275 is only 0.6" taller. Makes the decision a lot harder. Is 0.6" worth mpg and minor performance decrease? Lol

 

In person his looks beefier, but I think that's just because he's got a much more aggressive tire. Do you plan on off roading at all?

 

Minimal off roading to be honest. My Tacoma is my daily so I don't add miles to my race car. Overal, I think a 2" lift should clear 275/70 according to other post on TW, but I'm not sure if it's worth losing a few mpg and performance for a tire that's only 0.6" bigger.

 

Honestly go with a 265 then in a P or standard load. I ran 265/70r17 in the standard load for awhile and I didn't notice any loss at all. Maybe .5 mpg? They even help up to light off roading while aired down. In that pic those are the General Grabber AT2s.

 

Thanks. I'll stick to 265/70/17 in C load then.

 

Good choice, if I could do it again, I would have gone with the 265 falkens instead of the 275 ko2s I bought.

 

I had them, they destroy your mpg

 

Can't comment on the gear thing, but yes they will impact MPG. I personally think it's worth it for a beefier tire, but that's just my opinion.

 

What would be the advantage of a beefier tire other than looks?

 

Typically if a tire is beefier, then it's more aggressive. That plays into affect off-road with increased grip. With all the other variables taken into consideration (terrain, drivers capabilities, truck set-up) the real world difference is negligible, if any, but it's still there. It's mostly looks, but who are we kidding? For most of us looks is a large consideration when selecting a tire.

 

Bigger doesnt mean more aggressive, its just bigger especially if we're talking the same tire in a larger size. If you go up you're losing acceleration with more mass, longer air up and down times due to more volume to fill. Then there's the additional expense of a larger size. The disadvantages far out way the advantages. People tell themselves bigger tires are better but in a lot of cases they're not.
