We use 235/85R16 in the common load range E.

For our big rig, why not load range G?

Our dually's can't take the weight after the tires are only 3 years old.

So where do I get load range G 235/85R16 tires?

I have to admit that you totally lost me on this. Are you saying that the load range E worked for 3 years and then quit working? In what way? Did they blow out? Tread wear out? You need to provide a lot more information to get an answer.

Harry hit the nail on the hear. Manufacturers install tires of sufficient size and weight capacity to safely handle the posted GVWR/GCWR numbers they use on the door sticker. This will include the wheels. Installing a tire with a higher load rating will likely do two things, one make the ride much harsher, and two overload the wheels if you inflate them to their full capacity. If you need to install a higher load rating tire to handle the trucks load, then you probably do not have enough truck. JMHO.

wow. A 80 psi wheel with 110 psi tires. Your kiddin' right ? Not many quality 16" G tires out there. AND you would need 110 psi rated wheels. If your going to buy new tires/wheels why not upgrade to 19.5 wheels and tires that are 110 psi rated. You can get 19.5s in the same tire dia as the 235/85 E tire. If you need G tires maybe your overloaded ?

Goodyear G159 comes in LT 235 85 R16 load range G. Our local Discount Tire carries them so any tire place should be able to order them if they don't stock. Problem may be they are 110lb tires, can your wheels handle them?? I use these on my 5er.

I agree with pnichols.

Tell us the tire brand of these 3 year old tires that blow out.
A brand new tire could blow if inflation pressure is not correct.

I have 110psi tires on 95psi wheels, but will never need to exceed the recommended tire pressure of 75psi on my RV.

Good points from all. Thanks.

On our big class A, we had two inside dually tires blow last summer, after only being 3 years old. So we changed them all out.

We will likely stick to the current setup, watch the weight loading, and keep new tires installed.

Seems converting to a 19.5" wheels would make need to change some tranny gearing??

You don't have to put up to 110 lbs. of pressure in a Load Range G tires. Just use the same pressures you would use in the Load Range E tires (80 lbs. max.) as is required by your rig when the manufacturer shipped it with E tires.

G rated tires are heavier built - so they will last longer at E tire pressures than E rated tires will at E tire pressures for any given weight your rig you might be exposing them to.

The heavier Load Rating tires will ride a bit rougher because of their stiffer side walls than their E equivalents .... and of course they will be more expensive!

Another way to get better tire wear at any given loading/pressure combination is to go larger in diameter if your vehicle's gearing and fender clearance allow it. Larger diameter tires generate less heat at any given speed and loading. (... don't go wider in width though, because this sometimes requires new rims - an unnecessary expense unless you need more width for other reasons)

I have been going oversize on tire diameter and tire load rating for years on various vehicles in order to extend wear time. However, I use only the tire pressures as recommended by the manufacturer.

I was told that G159's in 235/85/16's were being discontinued. It wouldn't surprise me if this Goodyear dealer was wrong again. lol
