It's not the vehicle capacity or GVWR that is to be reduced. It is the tire load capacity you see in tables or molded on the tire sidewall that is reduced.

Tire capacity should exceed the actual load so in your case the actual load needs to be less than (tire capacity-9%).
This is by axle when you have GAWR which should be on a certification label or you should be able to get this from your vehicle dealer.

You cannot take the total capacity of all 4 tires and compare with the total vehicle weight as the weight is not equally distributed F&R r & L

I write a blog on RV tire application and safety.
Also give seminars on tires at RV events across the US. 40 years experience as tire design & quality engineer for major tire mfg. Freelander 23QB on Chevy chassis is my RV

But jwhybrid2b just took the GVWR and reduced it by 9% I don't see were he states his max tire load? If his tires are rated for 9% over his GVWR or GAWR which ever is closer to the max tire load, than he does not need to reduce his GVWR.

Just had LT 'E' load range tires put on today. Truck definitely feels more solid to the ground in comparison to the P rated tires that were on there originally.

Looking forward to feeling the difference when hauling the TT.
