Mixing tire load ranges on a 5th wheel

[Lifetimecamper]

Hi everyone! I'm in the process of replacing tires on my used 2005 Cardinal M-29WB . I noticed that the camper has Kenda Klever LT235/85R16 E tires.
The manual I have calls for LT235/85R16 G not E.
I'm thinking of replacing one tire at a time starting with one that has small cracks in it.
Questions:
Can I replace just one at a time?
If so, can I move up the load range to G on just that one tire as it will increase the tire pressure?
I'm dizzy from all the tire choices, reviews and horror stories. Can you recommend a reputable tire that won't break the bank? I'm disabled so my income and expenses has to be a factor. I know, I've picked an expensive past time for the past 57 years.

A tire person will be along........ My opinion, single replacement no..... maybe in pairs if they are the same size.

Not bashing anyone here and read the circumstance, but is this a trick question?????

Just curious why do you think that?? I am a little slow but .......

[dieselguy]

Lets just say I'd pursue saving money as it becomes available and getting 4 matching tires of the same specifications all at once no matter the circumstance. The OP's question kinda hit me like a "changing oil one quart at a time" scenerio.

His question is very typical of my thoughts. I don't have the money to replace all tires at once. I would have in the past considered one at a time Now I would consider two at a time. Make perfect sense to think that just not a good idea. I have owned cars years ago with four different tires.

I am going to bump this back up hopefully you will get a better answer. Do all 4 is the best answer but I do think you could get away with two if they are the same size as the other two one would not be good.

Good Luck........

I think for the most part, you'd be OK. Yes, doing two at a time would possibly be better but as long as they are the same size, the trailer and the axles will never know.

[Lifetimecamper]

Thanks everyone. Not meant as a trick question. I was hoping that someone would recommend doing 2 at a time. There are 4 tires altogether. I just didn't feel comfortable replacing one on one side. Something was telling me to do both. Now you've confirmed it.
DIESELGUY; now that's funny

[BigTJohn]

Needless to say, all 4 is best but doing two at a time, on the same side should be acceptable.

[phillyg]

I think conventional wisdom is, if changing only two at a time, they should both be on the same axle, not the same side. Also, OP should ensure his wheels are rated for LR-G before putting on the higher range tires.

[BigTJohn]

Philly... You are correct. I miss worded my statement meaning same axle but stated same side it's the axle, not the L/R side which should have the same time and profile/tread.

PHYLLYg. I'm currently running Kenda Klever LT235/85R16 E's but when I look at the manual, it says to run G's. The Kenda Klever tires look original.
The GAWR is 10,400 lbs. and the GVWR is 12,470 lbs.

Hey Lifetime. 33 years in the tire business qualifies me to answer. If the trailer manufacturer recommends G load range then DO NOT put load range E on your TT. It is all about load capacity. The only way to know if you can use LR E is to know the weight of the tt fully loaded by having it weighed. Devide the weight by the number of tires on the trailer. Check the load capacity on the tire, it is embossed on the sidewall. If the load capacity on the tire is not greater than the number you got when you devided, do not use that tire or it could seriously overloaded. Overloaded tires generate heat which can lead to tire failure. We have all heard those horror stories. Tires with higher ply ratings, like G versus E, are built to handle more air pressure. More air means they can carry more weight. Your rims also have a maximum air pressure stamped on them. Do not put a tire on a rim that can carry more air pressure than the rims because rims can fail also. Do not take chances with your tires. You can cut corners with some things but don' do it with tires. Better safe than sorry. Hope this helps and happy camping.

Thank you Mr. Tireguy! Looks like I have some investigating to do. Your advice makes perfect sense. If the manual is calling for "G" rating and there are "E"'s all around....it looks like someone, before my father in law who had this 5th wheel before his recent passing, went the cheap and dangerous route. I want it to be right. The info you provided will have me outside tomorrow checking numbers. Reading the actual numbers and getting it weighed makes sense.
I am married to someone who has to take the whole house with her when we camp. May have to get new rims too and "Z" rated tires LOL. Thanks again!

A blowout is not fun, dangerous and potentially expensive. Start socking $ away for better tires. The bad news is tires can look great but be "tired" due to weight or age ( very similar to human beings &#128563

[Lifetimecamper]

Thanks Silver
I've seen my share of blowouts on Motor homes and the damage they can do. That's why I want to get this right

Your tires are rated for 3K at 80 psi. This is not a dangerous situation load rating wise, maybe age wise though.

Hey everyone. So, I took the advice given here and did some checking. Good thing!
I found major cracking in between the treads of all four tires
Looks like I'll be replacing them all and will likely do the brakes while I'm at it.
Was hoping this wouldn't be a can of worms but it's a camper....expect anything. Yeeesh!
Anyhow, thanks so much again for all of your help. Happy camping!

Just make sure your wheels are rated for the extra air pressure that G require. Should be stamped on back side of wheel. G it should show 110 psi. If only 80 psi get E
