Hello again.... I have my 98 5.7 Vortec C2500 Ext cab, LB. I do Not haul anything in this truck as a daily basis. I have used it to help move my brother and his family last year, but not regular hauling or carrying, this is my daily driver to and from work. I have load range "E" on the truck now, and will be looking for a new set of tires this summer. Do I need to go back with the "E" load range tires or can I step down to "D" load range? And if so will the stability of the truck suffer? meaning will the truck sway from side to side while driving?

Thanks
Darryl

 

Based on the suspension of the truck and the fact that it is heavy duty they call for a tire pressure which only load range E can handle. You can absolutely switch to and Lt (light truck) tire (same type used on a 1500) if you want just do not set them to the tire pressure stated in the door. The truck will probably even ride better. Set the pressure to 35 and keep a close eye on the wear. If the middle of the tire is wearing more then outside edges lower the pressure. If the outside edges are wearing more than the middle then raise the pressure. By law tire shops are not suppose to down grade the load range or speed rating called for by the manufacture so you may have a hard time getting them to sell them to you.

 

@MDTAHOE...... Thank you very much, yes the truck does ride like a rock with the E range and 80psi. Im glad that the lower range wont affect the truck in a bad way, and any additional smoother ride I can get will be a great help. I am going with Michelin LTX this spring in the D range. Thank you again so much.... You are a great help and a major problem solver for the site.....

You can also try lowering your pressure to 65 all the way around. You should get a much better ride and good carrying capacity.

 

IMO, the truck won't handle as well,

under large loads.

Or as well on hard curves, or the highway.

Oh, and the tires, of course, won't last as long.

Other than that, you're good to go.

 

@Therewolf....thank you for the info... I dont haul anything with the truck ... it is a daily driver and highway cruiser and maybe a weekend helper for things.
I am going to go with MDTAHOE... I feel that is the safest way, instead of just lowering the pressures... Thanks to all that have replied

 

It would be a good idea no matter which tire you run to see what the suggested min and max pressures are from the tire manufacturer.
