You need to know what wieght you will literally be putting in the axle. If constantly over by a few hundred lbs, get a stronger capacity tire the next time around.
My funding with driving and loading trucks, going to a bigger size, or wieght rating, if I only need new load rated tires at a D 8 ply psi, the pricer E 10 ply rated tire does NOT carry the load any better. I'm better off saving my money.
If I go up in size, I can go down in ply load rating too. UNLESS I need addition load carrying capacity.
My experience is probably similar to Grit using light duty trucks in a construction use. Including running down the road at 150% of tire capacity. I should point out too, in usually on city county roads doing less than 50 mph for 5-10 Mike's, not freeway at 60 in 90f temps. Your mileage may vary in this. I'm also within legal axle loads in WA st which is 500 lbs per inch width of tire, along with a paid for gvw for loads I carry.

Hard question to answer with out knowing your payload, depending on what is carried in the TV, there are likely some combinations that it might be possible.
[emoticon] So even if under payload, it's still possible to exceed the rating for axle or tires?

Just my opinion but payload ratings are meaningless imo. Know your axle and tire ratings and stay within those and you'll be fine.

Huh? That is probably the most succinct, easy to answer correctly, question that has been asked on here in some time! LOL
The answer is no you don't need to worry 1 bit, about any component, based on the mfgs rated payload. Seeing as it is always the lowest common denominator of components' capacities, often combined with regulatory limitations that further lower the "rating" artificially, the only way one could be more conservative is to place their own personal unfounded factor of safety ON TOP of the mfgs rating.

This is so clear cut that I can't even think of an obtuse response considering some obscure condition that someone on this forum generally brings up anytime someone uses words like "always", "neve", "certian", etc.

Hah, shelby, I found a rv.net obtuse answer I hand't thought of...
"What if" someone put the same size P rated tires on the truck? LOL

So, springs, transmission etc don't matter?

Actually it's very EASY to overload an axle while still UNDER payload.
Put a 3000 lb pallet of sod, concrete blocks/paver on and in the very back of an 8' box truck with a 6000 lb ra capacity. You will probably be over the approx 3500 lbs of load capacity for the axle rating.
You will lower the rear enough that you start pulling wieght off the FA onto the RA, putting it over it's capacity.
Yes been there, done that.ore fingers and toes counting than grit and I have combined.
Likewise depending upon the truck bed length, you can put a load in the very front of the bed, for my IHC, 4-5000 lbs in the front 4' of the bed on pallets will add 2000 lbs to the FA overloading the 8000 gfaw of that truck. It has typically about 5900 on it empty. 12000 lbs to axle limits, 14000 to legal registered legal weight limit.

Reality, very easy to overload an axle! That is the way MOST commercial drivers get over wieght tickets, by not balancing the load so an axle is not over wieght, but under there paid for gvw.

SOOOOO true!!!

Simple math on my truck. SAE RAWR 9,750#, now add that to my 5,250# unloaded front axle. HMMMMMMM that is 15k. But But how is that possible when my GVWR is 14k.

FishOnOne - thanks for your comment. I was also surprised that it came with Continentals not Michelin’s. I have lots of good experience with Michelin’s but not any with Continental’s, but the tire guy I talked with had high praise for the Continentals.


Yeah I forgot the 18" tires are Continentals which historically have been decent tires at best.

Thanks all for the insights. I’ve decided to run the stock tires and apply the money to some Li batteries which will lighten the load a little. When I do replace the tires in a few years I do plan on upsizing though.
