My tire size is 285/70/17. I did not recalibrate yet. I know the mpc difference and take that into account but my normal driving has dropped and I'm not pushing it

Mine dropped too. I have 275/70/18 so they're about the same height. Its the weight of the 10 ply tires mostly. Gearing is a little different, but in stop and go, the weight is the biggest thing. Mine dropped as well.

Only way to truly fix it is to go back to stock tires... NOT WORTH IT (in my opinion)

But you could get a custom tune from DiabLew, those seem to help a little bit.

Just dont let the dealership know you did it.

(Sorry in advance if this happens to be a dumb question)

 

Why do people seem to fret slightly when going from a 45lb tire to, say, a 60lb tire? I understand that it would take more to turn the wheel because of the added weight, but in the grand scheme of things, that's only an extra 60 lbs of weight added as a total (15lbsx4wheels).

 

But that 60 lbs of added weight is next to nothing, considering when you are driving alone you alone are adding 130-200lbs to the truck by your own weight.... then if you have at least one passenger (wife/significant other/friend), there's another 100-150 usually added to that. So why do people fret about adding 60lbs of unsprung weight to their truck when they already add 200-300lbs by getting in the vehicle?

 

Again, I apologize if it sounds dumb, that just happened to run through my mind the other night. If somebody could set me straight, that'd be fantastic.

Doesn't every pound of un-sprung weight equate to something like 10 pounds of sprung weight?...so if that's true 60lbs would be a noticeable difference. I'm probably wrong with the conversion but don't thing it's 1 for 1.

The rotating weight of the tires is not equal to adding weight into the pickup.

If you drive around on stock tires, then put another set on that adds 15lbs per tire, it is a VERY noticeable difference in acceleration because the truck is having to turn that much more weight.

If you were to just add 60 lbs into the truck, you wouldn't even notice. Even adding a few people into the vehicle isnt as easily noticeable in regards to performance and acceleration.

 

I race mountain bikes and in bike racing, you notice a VERY large change in the handling characteristics, acceleration and overall performance of the bike as soon as you drop weight in your wheels/tires/drivetrain (any rotating mass on the bike) because of the energy it takes to rotate that weight.

So in competitive racing you see people spending more money upgrading wheels than you do on most of the other components, because its the smarter place to put your money.

I thought about trying to squeeze those onto my truck for my next set... not sure if they will fit with just a 2" level and stock wheels (maybe +18 offset wheels if I find a good deal on the ones i want)

Thanks for the info, my thought process was spinning the tires with the weight "over" the tires would be similar to having the weight "in" the tires.

 

That makes sense, I appreciate you explaining that to me.

 

So in essence, would that result in excessively accelerated wear/tear on powertrain components? Drive shaft and axles used to turn the wheels? I would think not, since there are a ton of people that add that kind of weight change, sometimes more than that, to their trucks, but perhaps they just don't care because they don't keep it long enough to matter? If you have info on this as well, that'd be fantastic.

It would make sense that it does put more wear on, because it takes more effort to get the wheels moving. But... its clearly not enough to matter. I've been running 10 ply tires for a long time and never had an issue. I know a lot of others on here run 10 ply tires as well and those heavier/wider tires weigh significantly more, so if it were to actually cause a problem that fast, you would hear about it.

No rubbing at all

Do you think the 2" leveling is necessary, or could one get by with less or no leveling?

    • 3.59 Kroger’s in Montgomery Tx. 20 cents higher than most around here. Very unusual. Saturday they were 3.49. 
    • Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks. 
    • Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL. 
    • $5.10 for regular at the Kroger   It's been 6 months... is this the "new normal" ?
    • Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
