Replacing tires on a 4-cyl .. 245's to 265's?

In the near future i would like to get some new wheels/tires for my truck and was just wondering if someone can share some advice ...
My factory tires are Hankook DynaPro HT in size P245/75R16 and the tires weigh 34.4lbs each. I was looking at the Faulken Wildpeak AT3 in the 4-ply in size 265/75R16 but noticed the weight is 44lbs each ... that is nearly 10lbs per tire more. What effects would these heavier tires have on my truck ?
Thanks for any suggestions ... i am mostly on road but ocasionally go off road to get to hunting/fishing spots. Im just after something that looks a little more agressive than my grandpa hankooks

 

I personally wouldn't go bigger in size unless you honestly needed the ground clearance. Yeah bigger tires look cool but it'll cause gas mileage and power to drop.

 

I just seen the Cooper Discoverer AT3 in the same size as my factory tire P245/75R16 and its just a couple lbs heavier but has a bit more agressive looking tread.

 

I have 265/70 16's and they're roughly the same diameter as the 245/75's. 10lb's per tire might make a little difference, but I doubt it would be that noticeable considering all of the forces at play. If it's really a concern get some alloy wheels which are probably going to negate most of the extra weight compared to the stock steel wheels.

 

I went from 215 to 32/11.5 on my 4cyl. Be ready for power loss, slow acceleration/top speed, and MPG loss. Keep in mind my tires are A/T.

Had to do the black box mod to get rid of my rubbing. Ground clearance is well worth it to me.

 

What transmission do you have?

 

I have the SR5 which had alloy wheels

 

I have the 6-spd Automatic

 

I have a 2.7 auto and the same alloy wheels.

I went from stock 245 Dunlop to a 265/75 Hankook AT and lost 25% of my fuel economy immediately.

I eventually got rid of them for Cooper ATP in the same size and weight you're quoting (they weighed about the same as the Hankook tires) and get the same mileage as I did before.

They're a light tire but the 2.7 is extremely sensitive to that weight.

I was getting 23/24 average and a high of 28, I have averaged 17.5/18.5 since going to 265/75 and the same trip I got 28 on I've not done better than 19.5 since. It's a regular route I take 6-8 times annually, so that's worth noting.

Don't buy 265/75 for economy. It is a substantially better looking tire size with slightly more ground clearance.

 

I tried 285 p rated tires at first and didn't really feel much difference but when I bought my truck it had 245 e rated tires on it so all in all they weighed about the same actually the 245's on steel wheels weighed a couple of pounds more than the 285's on aluminum wheels. I have since switched to 1st gen tundra aluminum wheels with 255/80/17 cooper st maxx the wheel tire combo weighs a whopping 87 pounds apiece. the truck lost a little power but not bad no idea about mpg's they're a great tire they are quiet and ride smooth for an aggressive at truck is a 2.7 at ac 2nd gen
