Ok I am having a serious brain fart..for some reason. I cannot figure out my towing capabilities of my truck...never towed more than 2000# in my other trucks in the past but now Im looking for a new TT . I have a 2010 4x4 supercab 145" wheel base with a 4.6l 3v EFI v8 with the 6spd auto and 3.73 axle with factory trailer tow package and while I was looking on my spec sheet on my truck..it stated 7000# GVWR package. I normally can figure this out easily but since my work accident my head hasnt been the same, and also on another question ..does anyone have this issue? I put a hitch carrier on my truck (type for motorized scooters) and then load up my mom-in-laws moterized scooter which weighs 250# and the carrier is about 75# with the ramp..well I noticed that my rear tires drop about 1 to 1/2" and while driving the tires show the drop..the tires are rotated and properly inflated..it almost seems like its over loaded but with my 07 F150 5.4 v8..wasnt a problem
thanks in advance

 

What tires? I had the crappy GoodYear SR/A 275/65-18 and they are a P-metric tire. Not even an LT tire, but I fixed that And that tire has something like a 2600 lb rating? They felt like bicycle tires when I took them off the truck, pliable and squishy. Sidewalls are not very firm. HTH- Tim

 

According the spec's chart found up in the Articles/Specs section:
https://www.ford-trucks.com/specs/20...d-f-150-1.html

Your truck: SCab 4wd 4.6L 3V, with 3.73 should be rated to tow 9400lbs.
The GCWR for truck and trailer is 15,100lbs. They come to that 9400lbs by subtracting your curb weight (roughly 5500lbs) from the GCWR.
Remember that any family members, dogs, coolers, bikes, etc that you have in the truck and bed will count into your total weight. So if you have 1,000lbs worth of human and extras, you need to come down 1,000lbs on the trailer.

The squat that you experienced with your mom's scooter doesn't sound too normal, but I'm not surprised honestly. 300lbs or so extended out off the bumper is going to make it squat some, but once the initial springs rest on the helper spring, you should be good to go.

Hopefully this helps a little.

 

I was also thinking that Chandler but he was asking about the tires dropping. Good call- great minds ya know? lol we got him covered either way.

 

Thanks Tim. Yeah I think we pretty much have it nailed for him.
OP - as Tim stated, heavier load range tires will certainly help. While you probably do NOT need an E-range tire, you could step up to a heavy C or D range tire. You will still keep some of the nice ride quality without a lot of the sidewall flex you're experiencing.

 

thanks fellas...appreciate the info..do agree that stock tires need to go and will soon..and from what Im reading I could tow about 9k but where does the 7k come from on my spec sheet that came off truck

 

Probably GVW and not GCVW I would say? C= combined, truck + trailer

 

7k is the GV-ehicleWR
You get that rating by adding your curb weight, and your payload capacity.
So your GVWR minus your actual weight = your available payload capacity.

There should be a sticker where rocker panel meets the door jam when you have the driver's door open, that shows your available payload for YOUR truck. The numbers above are generic, close to but not specific to your truck.

 

thanks again guys...now I feel more comfortable about buying a TT that is about 6K and that gives me room with my family and incidentels..gonna buy new tires anyways as I want something more agressive looking and handling for when I go off the beaten path

 

Anytime, you're more than welcome.
Post pics of your new purchase(s) once they're on!
