ZACTLY!!!!!!!! OP simply place 3/4" plywood under each RV tire with Truck and RV on LEVEL ground. Now what do you think???

OH and one persons 8 years of good tire experience does NOT make the tires overall performance of all those tires "STELLAR". Lantley NOT referring to you.

OK reading further place a 2X under each tire instead.

OP here......Wow.....I should have checked back sooner.

I will add a little bit of information here. Yes my 5'r came with load range "D" tires. Factory rims and tires are 6 lug wheels rated at 80psi and ST225/75R15 tires. My trailer currently rides out of level pretty bad. It is about 6" difference from front to back. I recently had a blowout on my rear tire and had to purchase a tire on the trip. I am going to be upgrading to a 16'' wheel and tire to gain height. If I go with the 235/85R16 I will gain around 1.75' of height. I have found wheels that will fit my trailer and are rated for 110psi. Did the tire blowout from too much weight being on the rear tires? Yes I am quite sure of it. Does a load range "E" tire add up to cover the max weight of my trailer? Yes it does. But why not go higher? I had no intentions of going to a load range "G" tire as some are suggesting, but......I am not against it. I really would like an all steel tire but I have not been able to find one in that size at load range "F". Also in my consideration is price. Why not buy an all steel higher load range tire for the same price as a Goodyear Endurance load range "E" tire. I am not a full timer but a frequent weekend warrior. You guys are way smarter at this than me and most of you have thousands and thousands miles more than me pulling a trailer. That is why I am here asking questions. Maybe I don't know what I am talking about or overthinking it. I am reading everyone's reply and have read almost every thread I could find on tires and heck...……..I still cant decide what to do. Thanks!!!

:S

Why not fix what I see as the root cause get your trailer as close to level as possible. Then worry about tires, I am sure you are putting a lot of extra weight on that rear axle. The equalizer can only compensate for so much out of level.

Did you read my post before you commented????? I AM fixing part of the issue of being out of level by adding 16” rims and taller tires. After mounting the tires I will re-evaluate and see if a subframe is needed.

That simply will not change all that much as you only gain 1/2 of the added tire diameter.

Well I got my last 2” to level with a Correct Trak system. I also raised my pin box one set of holes, to bring rail clearance down to 6”.

Also ,if his leaf springs are under the axles, getting them on top could also be an option that he is not aware of .

Yep, difference in tire sizes would be around 3.5", which would translate to 1.75" ride height difference.

That's what I get for skimming over all the posts, I missed where that was pointed out ... Just wanted to make sure the OP knew he would only gain half the difference... Thanks

No the difference in height is nearly 3.5” between what he has and the 235 /85/16 , so half that 1.7”

gain 1.75" in height..??? IF the tire and wheel measurements are that, You will only gain half of that ... which is 7/8"

Understandable on a rv website. When it comes to tires on a trailer everyone has a opinion.
Some opinions are based on what that owner did on one or two trailers.
Another opinion may be based on no experience but just a opinion based on tire mfg hype.
Others may be full timers with several trailers and many years of using trailers.
Others may have pulled commercially with hundreds of thousands of miles using this type of equipment using dozens of tires.

So yeah its hard for new folks to decide what going to work best for their situation.
AS others have said going from your OEM 225/75-15 to a 235/85-16 will gain around 1.7" in height.

It’s the OP that said he’s gaining 1.7 with the 16” tires. He knows where he wants to go , just needs a tire that works . IMO 90-95 psi in a G rated tire is not a bad choice .
