Paasenger tires on 4x4 BT Titan

[jbone]

Why would they put passenger car tires on a Titan with 4x4 and BT?
The sidewalls on a passenger tire are weak compared to that of a LT tire.I bought my Titan for towing and did not notice the tires.Are they adequate for towing?

Note: My Titan has the Off Road pkg. so I have the 17s, but it also came with the Big Tow package. If you have Big Tow alone you would have one of the 18" wheels/tires, but the load comparison below is typical of the difference between passenger and light truck rated tires.

The passenger rated BFGoodrich Rugged Trail P285/70/17 (an all-season), is stock on the Off Road package.
It has a maximum load rating of 2833 lbs. at its maximum inflation of 35 psi.

The light-truck rated BFGoodrich AT KO LT285/70/17 (an all-terrain), is a very popular aftermarket upgrade.
It has an maximum load rating of 3195 lbs. at its maximum inflation of 65 psi. but to even match the Rugged Trails load rating, you would have to run it at almost 55 lbs. psi. (while at 35 psi the BFG AT KO in this size, has a maximum load rating of only 2105 lbs).

The Rugged Trail is probably more cushy, handles better, and would probably make more sales at the psi values for the payload. It's biggest draw back is that they wear out before 25K miles for most of us.

Many that buy aftermarket tires still get passenger rated tires. Here is a list I put together of 17" and 18" stock size replacement tires, (both light-truck and passenger rated).
17" & 18" Stock size replacement AT tires.

The SRA's that come on the non off-road package titan LE and SE are rated at 2601lbs load per tire, so they are technically within spec for the GVWR on the Titan. I have towed ~6Klb load with zero issues - truck is very stable. I have the SRA's.

my stock RT tires have 29k on them and I thinK I can squeeze a few more tousand miles out of them without any problems. I usualy keep them under the recomended pressure at about 33-34psi.
