Trail Boss Duratracs Load Range

[ShamrockShooter]

I was thinking of having the dealer swap out my duratacs (keep them for winter rims) and put on a quieter all terrain tire while it is in the shop for the leaking rear window.

 

Since my truck isn't with me to check, does anyone know what load range the OEM tires are?

 

Looking at the gm my certified service website there is quite a difference in price for the LT 275/65/18 load range C vs E.

 

I am not a tire guru so not sure what load range tire our trucks need.

 

Thanks

The Chevy build website says lt275/65/18C so I am guessing they are load range C then? E rated tires are about $75 per tire more expensive

Unless you go rock crawling, drive on gravel roads a lot, or haul or tow heavy, you want the LT Load Range C tires.  They have less plies than the LT load range E tires, which translates into a better ride, less weight per tire, and maybe a little better fuel mileage due to a little lower rolling resistance.  

 

If you are going to another on/off road all-terrain tire, you can go with "P" (passenger) rated tire for an even better, quieter ride.  But make sure the load capacity is the same (the pounds the tire can carry are stamped on the sidewall), unless you know you are never going to haul or tow anything.  And your TPMS alarm may go off, as the "P" rated tires are inflated to a lower PSI (say like 44 psi max) than the "LT" rated tires (say like 80 psi max).

Thanks. With the $100 Chevy mail in rebate plus the $200 gm card mail in rebate I can get LT 275/65/18 load range C Goodyear Wrangler At adventure Kevlar installed at the dealer for $500 total before tax. They might not be the best tire in the world, but for that price they should be good enough and provide a much quieter ride than the duratacs and still give me some "dirt road" ability which is all I do for off road.

What I am seeing is there are very few load range C tires in LT 275/65/18. Most are either P or load range E in this size. Must be something off an odd ball size for none load range c tires.

 

What load range to the 20 inch trail boss tires come in?

What tire pressure are y'all running?

 

I just got 275/65-18 Duratracs (American Racing AR931 wheels) from Tire Rack.  Load Range C...51 PSI max.

 

For the life of me, I can't seem to find the "sweet spot" with PSI.

If that is the tire size and load range as the truck was born with, then the door sticker still applies. 

 

Sticker pressures are those for when at rated load.
