Tire Replacement???

I searched the forum and didn't find anything regarding this situation specifically so I apologize if I'm duplicating conversations...

I had my first blow out today and am going to replace all 4 tires with Goodyear endurance. Upon my search for my OME tires, size ST 225/75 R15 load range C max psi 50, I could only find the endurance load range E with max psi 80. To get to load range D, the tire size is 205/75 R15 load range D max psi 65. (I realize there are other tire manufacturers with same tire sizes and load range but I want to buy a better set of tires).

My question is...will I be ok using the load range E tire? Will my rims handle the psi pressure? I looked on the back of my aluminum rims for any psi ratings and couldn't find any. All I could see was a max weight of 2150.

Any advice you can give me would be appreciated. My next trip out is in a week and I'm told by tire shops around here that I have to order them online and have them installed as they don't carry a lot of trailer tires.

There is a huge amount of information on this subject, here. I just bought that tire in the load range E at Discount Tire and I could not be more happy. There was even another TT there, doing the same. The TT feels nice and smooth on the highway. The 15" tire was one of the reasons we selected this model from Surveyor.

p.s. I asked the same questions from several tire dealers; all said no problem.
They all said the LR E tires is supposed be at 80 psi to keep the sidewalls firm.

If you're not sure of your rim's pressure rating, you CAN use the Load Range E tires, but inflate them to only 65 PSI. Use metal stems if you can.

Then, use the weight-carrying specs for Load Range D tires of that size.

Or buy all new rims that CAN handle 80 PSI, and go with the carrying specs for L/R E's.

Get the load range E. That is what I do with my Maxxis. Just fill them to what this table says for the load you are carrying.

https://www.goodyearrvtires.com/pdfs/rv_inflation.pdf

See if any dealers carry the Maxxis. They are proven(been out longer than 18 months) and most dealers can get them quick. My boat trailer and TT have Maxxis on them.

That 2150# - orange above - is probably for a 5 lug/bolt hole wheel. Is that what you have? OEM wheels may have more than one rating on them. Does it read 5/2150? What does the certification label read for GAWR?

That 8884 is probably the GVWR. The GAWRs are most likely 4000# making the 2150# wheels legal fitments.

You should make sure there is/is not a PSI specification associated with those wheels before you inflate your new tires to 80 PSI. Email the wheel manufacturer for confirmation.

Make sure the wheel valve stems have a PSI rating above what you're going to use. It's recommended to use steel valve stems when replacing them on RV trailer wheels.

well, I had my Endurance tires mounted today I did some research on the rims. And from what I can tell is that the rim can handle the more pressure its the valve stems you need to worry about so I had high pressure stems installed and aired them up to 65 lbs. I think that will be a good ride and allow me to use that stiffer sidewall. I will be towing in another week can't wait to see how it goes. thanks for all the good advice and opinions I hope I made the right decision???

If you have the Series06 aluminum rims, the 15x6 5x4.5 are rated to 2150lbs @ 60psi.

Agree to go with E rated tires and lower pressure as these are more durable against damage and nails or other road hazards. Also suggest not spending extra money on highly advertised expensive extra mileage trailer tires. The issue is that most of the time all tires after 4-5 years develop weather cracks on them and need to be replaced, long before you wear them out. I put 10 K + miles on my 5th wheel trailers a year and have yet to actually wear a tire out before I had to replace them due to the weather cracks.

well, as promised I spoke to Lionhead today about the specs on my rims. I have the Bobcat size 15x6 5-4.5 bolt pattern maximum load 2150 lb. they told me that as long as I installed high-pressure valve stems I can put whatever max psi on the tire sidewall said.so I have load range E max psi 80lbs. I could put the max in but only going to start out with 65psi and see how it rides the first trip is tomorrow Just wanted to pass this info on so others would be informed. Thanks for all the help I received Happy camping
