2000 Ford E150 Converison Van call for 2357515XL tires found a great deal on some used BFGoodrich ALL TERRAIN TA K02 LT235/75R15 104/101 S tires I dont drive the much these days but need to replace the rear tires so i decided if i got these tires at the good deal might be something i d do , now if can put them on without tire s popping on me they are rated at 50 psi do i inflate them that or stick to the 41 psi, stats of tires i want r below any feedback is appreciated

The correct answer is you inflate the tires to whatever pressure produces a full width contact patch with the load you are carrying. In my experience that will be somewhere between 30 and 40psi with a 1/2 ton truck and you will probably never apply the full pressure rating.

 

So do u the BF tires will work as they are not rated as XL tires?

 

I found this at the Tire Rack. It presents a good explanation regarding XL rated tires and load qualifiers.

Tire Specs Explained: Maximum Load

(Lea en español)
Maximum Load

A tire's maximum load is the most weight the tire is designed to carry. Since a tire's load carrying capacity is related to the tire's size and how much inflation pressure is actually used, maximum loads are rated with the tire inflated to an industry assigned inflation pressure.
Additionally, load ranges are used to separate tires that share the same physical size, but differ in strength due to their internal construction. "Higher" load ranges are used to identify tires that have a stronger internal construction, and therefore can hold more air pressure and carry more weight.
Each load range has an assigned air pressure identified in pounds per square inch (psi) at which the tire's maximum load is rated. Listed below are the air pressures at which maximum load is rated for popular P-metric and LT tires:
P-Metric Passenger Vehicle TiresLoad RangesAbbreviatedMax Load PressureLight Load(LL)35 psi (240 kPa)*Standard Load(SL)35 psi (240 kPa)*Extra Load(XL)41 psi (280 kPa)**In an effort to internationally harmonize load ratings and ranges, recently introduced and future LL, SL and XL P-Metric sizes will use ISO/Euro-metric maximum load pressures of 36 or 42 psi Euro-Metric Passenger Vehicle Tires Load RangesAbbreviatedMax Load PressureStandard Load(SL)36 psi (250 kPa)Extra Load**(RF) or (XL)42 psi (290 kPa)**Reinforced and Extra Load nomenclature may be used interchangeably to designate heavy-duty tires LT-Metric and Flotation Light Truck Tires Load RangeAbbreviatedMax Load PressureLoad Range B(LRB)35 psi (240 kPa)***Load Range C(LRC)50 psi (350 kPa)***Load Range D(LRD)65 psi (450 kPa)***Load Range E(LRE)80 psi (550 kPa)***Load Range F(LRF)95 psi (650 kPa)******Industry standards specify selected large LT tire sizes be designed with reduced maximum load pressures
P-metric tires used on passenger cars and station wagons are rated to carry 100% of the load indicated on the tire's sidewall (or listed for the tire in industry load/inflation charts). However, if the same P-metric tires are used on light trucks, (pickup trucks and sport utility vehicles for example), their carrying capacity is reduced to 91% of the load indicated on the tire's sidewall. This reduction in load results in causing light truck vehicle manufacturers to select proportionately larger P-metric sized tires for their vehicles to help offset the forces and loads resulting from a light truck's higher center of gravity and increased possibility of being occasionally "overloaded."
For example, P235/75R15 P-metric sized, standard load tires used on cars and light trucks would be rated to carry the following maximum loads at 35 psi:
CarsFull Value2028 lbs. Light Trucks 9% Reduced Value1845 lbs.
Additionally, while a tire's maximum load is the most weight the tire is designed to carry, its load carrying capacity at lower inflation pressures is proportional to how much inflation pressure is used. For example, P235/75R15 P-metric sized, standard load (SL) and extra load (XL) tires used on cars would be rated to carry the following loads at the inflation pressures indicated:
Air Pressure (psi)20,23,26,29,32,35,38,41,
P235/75R15 SL1543,1635,1753,1852,1940,2028
P235/75R15 XL1543,1635,1753,1852,1940,2028,2105,2183

Note: 35 psi is the assigned "maximum load" pressure for standard load tires and 41 psi is the assigned "maximum load" pressure for extra load tires.
The above chart correctly shows that an extra load tire is not rated to carry any more load than a standard load tire when both are inflated to the same pressure (up to the standard load tire's "maximum load" pressure of 35 psi). This is because a tire's load capacity is a function of its size (which determines the size of the "air chamber"), its construction (which determines how much pressure can be held) and the actual air pressure used (which determines how many air molecules are forced inside the chamber). Tires with equivalent physical dimensions typically carry equivalent loads (until they reach their maximum load pressure).
The tire's maximum load is indicated in relatively small sized print branded near the tire's bead (adjacent to the wheel) indicating the appropriate value. Because tires are global products, their maximum load capacity is branded on the tire in kilograms (kg) and pounds (lb). These values can also be found in the industry's tire load & inflation charts.
Note: P-metric and Euro-metric sized tires' "maximum load" inflation pressure may be, and often are, different that the tire's "maximum inflation pressure."

So i assume from that post i can run the Bf tires long as dont load my van to full capacity

 

The BFGs have a higher load rating than the stock tires so you will probably never push them to their limits. LT tires start at 6 ply while the stock tires were only 4 ply, that means the LT tires will ride a little firmer but will also deliver better handling.. there will be less sway and jiggling around so IMO you will like them better.. just don't inflate them to max pressure or you will experience a harsh ride and poor traction.

 

Thank you for your reply, do you they will fit on the front without any rubbing?
