I am thinking about getting tires, the size is 30x9.5x15.
With my stock sepensions.

How much weight can I put in the back of my truck before the tires will rub?

I usually carry trash back there nothing heavy.

Now this year I might be carrying sandbags, for preperation for the hurricane season.

I won't load it up too the fullest. when I see the truck kind of going down I will stop.

But I was wondering with bigger tires how much weight i can put in the back.

 

your usual weight can be handled easily, nothing changes. it can handle the same workload it could stock.. just dont go more weight than your tires are rated, but that shouldnt be a problem

 

Its a Ford, they only rate it for half what it can handle anyway....LMAO.

I wouldn't worry about the larger tires if I were you...

 

Does that mean not to get the tires, or don't worry about the tires rubbing. Sorry, I am not thinking straight. Just Finish My second test of the day.

 

your engine will let you know its to much before your tires start to rub.... and if not you should have a inch or tire room after your on your bump stops

 

With 30x9.5R15 tires, nothing should rub, even beyond max payload.

You'll hit the rubber bump stops before your rear tires hit the fender wells.

I've had right at 1300# in the back of my truck (marble tile & granite), and the bump stops made friends with the rear axle, but the tires never rubbed anything.

Load that truck up! Most Rangers have over 1000# payload ratings, so have at it.

 

Thanks, for the reassurance.

Where is the rubber bump stops that you guys are talking about?

What does it do?

 

It stops the truck from going down any farther so your tires don't hit and you don't bend your springs too far. They are rubber or polyurethane, you will see them on the frame over the rear springs....

 

Just look at the frame behind your rear tires and you'll see a rectangular rubber thing hanging from the frame. As you load you bed, the springs compress and that rubber bump stop gets closer to the axle. If enough load is placed on the rear suspension, the bump stop will contact the axle.

If you ever put a failrly large load on your truck that sags the back end, but it doesn't quite contact the axle, drive down a bumpy road. Get out and look- sometimes you can see where it hits because the dust will be rubbed off the axle in that place.

 

Thanks, I will check it out.

 

if you look up the tire your getting it should tell you how much they can carry.
