Which of the following tires would you NOT recommend?

[Winged_One]

I think I am going to replace my Road Rider ST 235/80-16 E rated tires before we go out west. After weighing the trailer fully loaded, it is putting down about 2750 lbs per tire (on the tires).

What tires would you NOT replace them with from any one of the following LT "E" rated tires:

Goodrich Commercial T/A

Bridgestone Duravis M895

Bridgestone Duravis R250

Bridgestone Duravis R500 HD

Bridgestone R265 5-Rib

Dunlop Rover H/T

Firestone Transforce HT

General Grabber HTS

Goodyear Wrangler HT

Goodyear Wrangler SR-A

Michelin LTX M/S2

Uniroyal Laredo HD/H


As I seem to have an odd size tire (80 series), which would you recommend? 235/85-16 or 245/75-16? Taller or wider? Room underneath for either.

Also, where should they lift the trailer to change the tires? (I cheated and used the lippert to raise the trailer for bearing maintenance).

I don't understand how having 7k axles matters. It just means they can handle that much weight correct? It doesn't mean the tires also have to handle that much weight does it?

That is, as long as I am only carrying 5.5k on each axle, the tires on that axle also only need to be able to carry 5.5k correct?

Or what am I missing?

Maybe you should take some time and read the reference provided below. It has loads of really good day-to-day information by an respected tire manufacturer that follows industry standards and guide-lines.

The section about plus sizing with replacement tires is not often published by other large tire manufacturers.

AS for the BS about the 110# rims weigh your 4 tires and use the inflation chart for the G tire and add 5psi to what is recommended and you will be running around 80-85 psi. This is directly from GY tech support for when you are up grading the tire to a higher rating.

I don't understand the logic of this. If you are going to run the GY614's at 80-85 psi why not save a bunch of money and just get the R250's or Ribs? IOW why spend all that money and get no benefit?

Because the G caracas is much stronger than the E rated tire. I used 80-85 as an example it may be higher depending on his actual load.

I went through the same thing when I was replacing my Carlisle ST tires: I was hauling less than 12,500 lbs. on 3 7,000 lb. rated axles. So why can't I run LT E-rated tires? And I got the same song and dance about rules and regs, and the gubmint says you shouldn't, yada, yada, yada.

I checked my wheels and found that I can run the higher pressure G-rated tires so I bought some, not Goodyear. If I couldn't have run the higher pressure I probably would either have bought G-rated tires and run them at 80-85 psi or just gone ahead and run the E-rated tires and said the heck with it.

I have since weighed each wheel and would have been fine with E-rated LT tires. Of course I would have been breaking the rules. 🙂

I have the Geostar 574 14ply and love em, so far have about 6000 miles on them, built like the Goodyear 14ply but less expensive....just my 2 cents worth

Tires should meet or exceed the GAWR on the placard. That is the law on new construction and you should follow that to insure that you or another owner has the correct tires installed.

Goodrich Commercial T/A (Some still fail outside the recalled ones, don't use it near it's max rating like HHII did with twin Laredo HD/H)

Bridgestone R265 5-Rib (Too much sipping)

Dunlop Rover H/T (NO opinion, But Too much sippingt)

General Grabber HTS (NO opinion, But Too much sipping)

Goodyear Wrangler HT (NO opinion, But Too much sipping)

Goodyear Wrangler SR-A (NO opinion, ButToo much sipping)

Michelin LTX M/S2 (To much siping)

Uniroyal Laredo HD/H (See comment on TA above, but Too much sipping)

If you you have 33"+ center to center on your axles then get the 235's! Less than 33" center to center, get the 245's!

On the positive side, the Michelin XPS RIB, Bridgestone Duravis R250 and M895 are top notch all steel ply tires. For a Poly carcass the R500 HD looks good. The Transforce gets good reports for one of the lighter poly offerings.

If your trailer has 7K axles, then none of these tires meet your requirement despite your actual weight.

Get the GY G614's from trailertiresandwheels.com have them mounted locally. They have great prices and fresh tires.

GY WILL PAY FOR DAMAGES!

I did the same on my last RV went from the E to GY G for 5 years and had even tread wear running at 85psi.

Your rims are probably rated at 110# anyway.

110# is a MAX pressure not what is required! Use the weight charts. I went from G to H recently and Don't run the MAX on the H.

If you have 7k axles I would vote "None of the above"

GY614's, Sailun S637 or Geostar (110psi rims required)

Also personally on a trailer I would go taller over wider

6k axles I would use any of the closed shoulder "rib" designs, such as the Duravis 250. (almost nothing in that list)
