Tire weight

If I get tires that are 9 lbs heavier per tire will it be noticeable on my 2.7L? Wanting to go 265/70-17 Wildpeaks but not sure how the added weight will affect the already anemic engine. Right now I have 26/65-17 BFG rugged terrain that weigh 38 lbs.
BTW I found the Wildpeaks for $114 on Amazon. That’s hard to pass up.

 

Changing size makes more of a noticeable difference than weight (as far as performance goes). Your only adding 36 lbs. What you "will" notice is a rougher ride. And more wear-n-tear on brakes and front suspension (over time).

 

Thanks man. Didn’t think about that.

 

My truck has load range E 275s (I think they are 265s-one size larger than stock. I fatfingered the earlier number) on it. Has had since before I bought it. I haven't weighed them, but I'm sure they are heavy. My gas mileage is much better than most report here and there haven't been any reliability problems. I don't think you will have any trouble.

 

My ray 10’s with nitto 285/75/17’s weigh 90 lbs each. Yeah...it’s noticeable, lol. It’s a 4 cylinder, it was slow before the lift and tires.

living in a flatland area, it’s not that big of a deal, however if I lived in NM or CO, it would be an issue.

 

It seems to accelerate about the same since the new tires...slow as shit. Havent been on the hiway to test the cruise (sucked before anyway). But man do they look cool!

 

Thanks for reporting back, good to know what people are experiencing with different tire sizes on the 2.7.

 

Just put 35s on it'll be fine

 

I "lose" 17 lbs per corner going from LT245/75 r16 BFG KO's to some P rated all seasons of the same size. That's 64lbs total, but the difference is night and day. 10% better fuel economy, and the truck feels like it has way better acceleration. It's easy enough to swap wheels back and forth, takes 30 mins.
If you're curious as to how much difference rotational unsprung weight makes, just try riding the same bicycle with a set of light weight wheels vs heavy downhill tires with straight gauge spokes. It makes a huge difference.

 

I switched to 235 85 r16 after my lift. All tires are e rated. First ones I went with were Cooper discoverer at3 at 42lbs per tire. Lost a little mileage over stock but not bad, still able to easily maintain 20 plus. When I first had these tire I also kept the stock on a separate set and changed back and forth. Always noticed a difference.

Next were Yokohama geolander g015 at 48lbs per tire. Noticed a big difference. Much harder to average over 20mpg.

This year I have a company gas card to pay for any mileage for work. Since I only do a tank at home every two weeks I went with duratracs this winter. Heavier still, around 50-51lbs per tire. Now I don't even touch 20mpg. Lucky if I get 17. That's of course driving 65-80 most places on the interstate. Even when home if I take it easy I still struggle to get 18mpg.

Tire weight makes a big difference as it's more weight your engine has to get rolling. Different than weight sitting on axles. If I lost my fuel card I'd be back on Cooper's tomorrow. They fuel savings would pay for the tires in a month with the mileage I do.

 

I run the 18in toyota limited chrome clad rims with toyo open country's on my 2011 2.7L Base with blue/yellow stock bilstein..
I honestly havent had much issues in terms of acceleration, i think the low end torque the trucks produce (which is great) help this out pretty well.
The only thing that I noticed a big difference was on, was the ride was a lot more harsh.

 

sure it will make a difference

gravity doesnt go to sleeep

no doubt you will run Larger tyres

both weight /size will affect initiall movement & acceleration

 

Yes, it is noticeable even on my 2019 V6, probably more so on a 2.7L. I went from 265/70r17 Dunlops tires/wheels to 245/75R/16s tires/wheels and immediately noticed the difference (very noticeable) in acceleration and braking. I have two sets of 16s - one set is 13 lbs lighter and the other set is 9lbs lighter. I even the difference difference between the two 16 inch wheel sets.
