Put on bigger tires and wheels

[Jonas]

I went from a 225/75-15 on a 6" wide steel rim to a 235/85-16 on a 7" wide aluminum rim.
I was a bit worried about being near the weight limits of my old tires rated at 2540lbs each. The new ones are 3640lbs each. Plus the taller/wider tires give more flotation and ground clearance when out on the beach or hitting the trails.

Nice! Always better when you can upgrade.

Looks good. Also looks like you lost a good bit of clearance between the tire and trailer. Hopefully that won't be an issue when the suspension compresses.

That was my first thought... don't hit no big bumps...

My first thought was...YOU TOW ON THE BEACH? That would be an invitation for disaster for me.

I understand the mod, though.

I actually still have tons of tire clearance. I could even go to a much taller and wider LT tire if needed!

Very nice setup!

I'm not the only one... there is a group of us that camp WAY down on the national seashore past Corpus Christi, TX. Once you pass the "Four wheel drive vehicles only" sign... you can go another 60 miles. We all have winches and recovery equipment, generators, etc.

We used to drive from Bob Hall to Cut o'Land when the pavement ended at Bob Hall... I had a '54 Ford Fairlane with the fenders cut out and ran tractor front tired with grooves to get by the law... Good times fishing both Big and Little Shell...

I'll be back at Big Shell in 2 weeks!

3640 a LR E??? I have the same size Sailun LR G at 4400# but at 110 psi which may not be great on the beach

Yes, 10 ply load range E at 95 psi.
Trailer tires are not trying to find traction on the beach, they just need to "float" on the sand. The bigger and wider the better but no need to air down trailer tires for traction.

[JRTJH]

Load Range E tires operated at 95 PSI are overpressurized. The maximum pressure for LR E (10 ply) tires is 80 PSI. Load Range F (12 ply) tires max out at 95 PSI and Load Range G (14 ply) max out at 110 PSI.

While you may not have any problems operating LR E tires at 95 PSI from heat buildup/increased PSI, you may well be subjecting those tires to ply separation/tread separation from the excess pressure. I'd watch those tires very carefully, especially when in operation at highway speeds.

I was quoting the info and recommended tire pressure printed on the sidewall.

I also thought it was kinda cool that the tire manufacturer printed their phone number right on the tire.

This is a first for me. Until this picture, I've never seen a LRE ST tire with a pressure rating of 95 PSI. If they were my tires, I'd want to verify that it's not a "Chinese screw-up" by forgetting to change the mold after a run of LRF tires.... But then, maybe it's a "load star thing" ???

1-800-Bangalore, India: “95psi? No problem.”

My thoughts/experience is as yours. When I saw this tire I did a short bit of research and found that TireRack (if I recall properly) has a table that lists LRE at 80 psi...ALL LRE tires. I looked at a couple more places and they all indicated the same. I then found a site selling some sort of tire made my Kenda (again, if I recall correctly) and it too had the 95 psi rating (called a Karrier trailer tire). Upon further research I found that the Load Star is also made by Kenda so maybe Kenda is upping the ante - or overloading a tire (a trait of TowMax/Trailer King).....??

[CaptnJohn]

When I owned my Cougar it arrived with Trailer King LR E tires. Went as far as contacting the wheel manufacturer to find they were rated to "80 # like all LR E tires". No time to order wheels so ordered Carlisle LR F tires and got rid of the rubber valve stems. Ran those at 90 psi without a problem but if I had one would have known I gambled and lost. I was surprised how little psi/temp the Carlisle gained as they warmed but would not suggest anyone gamble that way as you well may lose.

You need to send a copy of that picture along with the rest of the sidewall information to NHTSA. It's a clear violation of safety to inflate a LRE tire to 95 psi (cold).

I suspect the molding information is incorrect. If so it would require a safety recall of all tires from that mold.

Again, NHTSA needs to investigate the matter.

LR E should be 80 psi, LR F should be 95. Many wheels that came with LR E tires are only rated to 80# cold psi... Could create a wheel problem or valve problem as 80# psi wheels are not always fit with valve stems other than rubber.
