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.

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 kindly

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 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

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.

I checked rims and tires

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
