No kidding. I had them set pressure to 65 psi, did you by chance see the max pressure for the rims? I looked and could not find it!

Tires

That bead damage looks like the installer tore the tire taking it off the rim, it could not have been tore like that and still held air. I have seen many tore like that when someone forgot to lube the bead before removal. I have seen it happen to brand new tires also when they were not lubed.

The max pressure that is stamped on the rim is 60lbs PSI. You shouldn't have a problem at all. The highest PSI that my TST system showed 72 PSI after running for about an hour and stayed there. That rim can hold alot more then what they have stamped on them........ there is also a web site for your rims, just type in the address that is on the hub cap.

I would agree with the installer damage, they were really wet on the bead when removed. The rubber just crumbles, you can break it and make it crack in other places. Former tire factory worker here, the tire looks like not enough heat when it was in the mould or poor compounding. Rubber should not crumble.

I could not find any max pressure stamp on the rims - just that the placard said they were 15x6JJ - which are good for 60 or 65 psi (still hard to find out which). If I had gone for E-rated tires, Steve Wideman at Sauder's said I'd have a hard time finding a reputable tire shop that would mount them on those rims.

I had them set mine at 58 but it was a warm afternoon when they did it. When I left on a 2.5hr tow last week it was a cool morning and they were 54. Once on the road, the TST TPMS showed they went back up to 61psi (at worst, when it was about 80F air temp on the 401 and between 85F and 91F tire temp depending on whether they were on the sun or shade side).

Note that tires don't always have to be inflated to their max pressure. They get inflated to the appropriate level for the load. GY has a chart for Marathons here that shows 65psi on the 225/75R15 supports the max load of 2540. That's 10160 on the axles (or about 12000 GVW allowing for about an 18% loaded pin weight). Not only would the Weight Police be after you but you would be breaking your 4000lb axles at that weight. Since your real-world weight on the tires is more likely to be a bit less than 8000lbs at your trailer's GVW, 65psi is significantly above what GY would recommend for that load.

Not to say the tires won't take it, however the ride for the trailer will be harsh, the axles will be being beaten up (the Torflex relies on the tires for at least part of the shock absorption) and the contact wear pattern will be towards the over-inflated side (with the associated handling and braking effects of over-inflation).

Even the 58psi I had them set at is a bit over-inflated but its a compromise I'm comfortable with. You may still be comfortable at max pressure. YMMV.

When towing I set my LR E tires on the truck to 60# Front, 65# Rear, trailer LR D tires are all set to 64#-65#. Have the TST TPMS on the trailer.

Truck is running 65 psi all around right now on E rated, I have no air bags, no squat, tows level. As far as the trailer currently at 65 psi always listening to max inflation camp here, i can let nitrogen out just can't add it at home was thinking of dropping to 60 cold to allow some expansion when hot .The trailer tracks much better than the defective Trail Distress slippers that were taken off. I would agree on E series tires not to mention overkill for the trailer as well the Rims not being beefy enough. As far as the weight police I am hitting the scales tomorrow when we leave. Looking forward to axle lift on the trailer at Goshen to take the extra weight off the back axle, can not drop the hitch any further or I will hitting the box when backing in at home or some Provincial Parks.

Same here. Goodyear Marathons came on my current trailer, and except for the spare being "shaved" by the factory, they worked great until I replaced them because of age. So far, so good on the current Goodyear Marathons.

I installed Carlisles on my Trailrmanor in 2007, and had no problems with those, but the current owners had 1 blowout/flat last year.....but they were a about at the end of their life expectancy, and I have no idea how well the owners kept up tire pressure. I say blowout/flat because they were not running a TPMS, so the tire could have just been run flat for a while before being discovered, causing damage to their trailer.
