"C" load final tire decision?

Here's a different angle of the stance.

 

I haven't had a good way to test it yet. In my neighborhood there is one of those digital speed limit signs that tells you how fast you're going and its pretty dead on. Maybe 1 mph difference but who knows the accuracy of the sign. Others on here have used a second gps to compare and say its spot on.

 

If you have a gps simply check your speedo against it.

 

I don't have one.. maybe there is an app that I can use instead.

 

You can use WAZE I think. It is a great driving app too. There's an option in there to turn on the speed readout. Not sure how accurate cell phone GPS apps really are but worth a try.

 

Is WAZE for android? I guess it's better than nothing.

 

Not sure what the truth is on that as many trucks come with tow packages and P rated tires. I would think for liability reasons the mfgs would not ship a tow package with P tires if it was an issue. From a personal side, I have towed fairly heavy for my 1st gen Tundra (Built FJ 40 on a 16ft, Carson Flatbed) with both P rated and LT tires on the Tundra. No real difference in towing that I could see. As long as the trailer is loaded right and you inflate the tires as required you should not have issues with either set up. The thing most folks don't consider is that at lower air pressures the P rated tires can actually be rated for a higher load than an LT. Most P rated tires hit max load capacity at 40-50psi where LT's can go upwards of 60-80psi for max load. Most mfgs only list load capacities for LT's at pressures above 35psi due to heat issues when you run them at lower psi. A good example is my Tundra came with P rated 265/70/16's and had a door sill pressure listed at 28 psi and my Taco Pro with 8ply BFG AT's of the same size listed a door sill psi of 41. Look at some charts and see what a P rated 265/70/16 at 35psi is rated for and what an LT of the same size is rated for at the same setting. Some P tires are rated higher load at lower pressures than the same size LT Tire. LT's get their load capacity at much higher air pressures. Toyo has a very good Load vs PSI chart on their web site...worth a look.

 

Droid and apple it is a very popular app right now
