Tire Information needed!

Hey everyone!!

I would like to purchase some tires but I would like
F or G load range. The problem I知 hitting is that the tire size goes up!!

My tire size is 225/75 R15 E

Does anyone know how far UP in size can I go??

Thanks so much for your valuable time!

Manny

Hello Manny. That's going to depend on a number of things, like the width of the tire (offset), the height of the tire, etc.. Which RV do you have?

From what I understand, most of us have changed the tires but kept the initial tire sizes. What they have done is gone to a much better tire than what is on the unit. Something like a G or H rated tire or a truck tire. You have to be careful because the rims sometimes will not take the higher tire pressures for new tires also. personally, unless you think you will have issues or your RV is not level when attached to your truck, you should stay with the same size tires for your rv. When I changed my tires, they were the same numbers that came with the RV but they were larger and wider. Didn't cause an issue except for needing to re-level.

Actual physical tire size among different manufacturers will vary greatly, even for the same size.


If your 225/75 R15 E are the "chinese bombs" than a good brand tire. GoodYear or what ever will be larger. Not by a great deal but larger.



I bought a same size set of Good Year Endurance replacements for our OEM tires. I could see the difference without measuring. And they were a higher load rating.





Good luck.

Thanks Frank!

From reading your thoughts, I should be ok if let’s say I go up one. For example

Present- 225/75 R15 E
Future- 235/80 R 15 G

As long as I don’t change the rim size and keep the other numbers to a minimal change.

Unfortunately the 5r doesn’t sit level. I’ve got a 2017 Ram 2500 Cumins that sits very high. My issue is some knucklehead (Oh, that’s me!!) purchased an Anderson hitch. The hitch only has (I think 3 levels) which is not enough to have the rig level. I figured since I wanted to change the tires anyway but increase the height of the tires and install MorRydes suspension on it. I was hoping all that would level it out just enough!

Thanks so much Frank! You obviously have a lot of knowledge and we all appreciate you!!

Ooraahhh!! I’m a retired Marine! Great to meet you here!!

Do you like your Good Year endurance tires? I’ve heard great things about them.

I think I’ll try one up on the tires. Leaving the R15 the same. (If I can) I’ll check to see if they make
235/80 R15 G

Thanks for your input!

Manny

Semper Fi! Thank You for your Service!


We bought them about 6 months ago from Discount Tires. They matched a deal from Sam's Club. So we got them pretty cheap.

So far, so good but not a lot of miles on them yet.



I feel a lot better having them after hearing all the horror stories. They also had a higher speed rating and load rating for same size. So we are "Happy Campers" to coin a phrase...haha


Good luck!
Bill

Just a note, I got the goodyear's with the exact size numbers as the china bombs that were on the RV. When they arrived, they were about an inch higher and way wider. They also hold 80 lbs of air verses 60 on the china bombs.

They are great, had them for a couple of years and 6,000 miles. We do store our TT inside. The are not overloaded and kept at 65 pounds coldm with tire minders (even have one on my spare).

There you go, you get what you pay for.



Was the load range higher too??? Mine were.

I got them online and the load range was higher. I think they were about $100.00 each. It was also very surprising that they were so much larger and more robust than the old ones.

If your old tires were rated for 60 then they were not LR-E but were LR-D. Suggest you review my new blog post ,"What size tire is it?"

Sorry, but I don't sell any products. As an actual tire engineer I just try and provide accurate info. Such as pointing out that 60psi is the inflation for LR-D tires. I point to my blog as I can't write the same info over and over and over. You can ignore the info and simply follow the info from non tire design engineers.
Wishing you, Good luck

It's not asking too much for you to contribute rather than promote your blog and advertisers.
