Need new tire and TPMS recommendations please

I posted this in the Wildwood forum, but I think this is probably a better spot.

My '04 Wildwood needs new tires, and I have no idea what to buy. The trailer's plate says 5200lbs, GVWR 7515lbs. I've tried to Google and get a good answer, but so far all I really "know" is I need LT or ST (and if I'm reading correctly, LT's start at 16"?)

The tires (probably factory, I doubt the previous owners replaced them, and I've owned it since Summer '09) on it right now are 205/75/15. Can I change the tire size??? (Say 225/75? I know I have to stay with 15...and if I can, should I?)

Sam's is usually my go-to tire place, as we move a lot. They have ST205/75R15 Goodyear Marathon Radial - Sam's Club. I'm not exactly sure how to calculate the weight rating? Do I multiply it by four, since my TT has 4 wheels? If so, I think I might need different tires? It says 1820 at 50lbs pressure, which would be 7280 if I multiply by 4....am I trying to hit that 7515 and have a cushion? We do tend to travel heavy. Our next trip will be 1700 miles and we will definitely be loaded down, as we're moving cross country.

Thanks for any advice!!! (If those tires don't fit the bill, could anyone recommend some that would, and possibly a place to get them installed? We're in Colorado Springs, CO right now)

Also, can someone recommend a decent, preferably cheap, TPMS for the TT? My TV has one from the manufacturer.

Wondering if Goodyear Wrangler HT - LT215/75R15D 106Q - Sam's Club would fit/be a better choice? Would REALLY prefer to stay with Sam's, but I will go elsewhere if I have to. Being military, we move a lot, but we've never not had a Sam's within an hour, which is handy for tire repair/replacement when needed!

I would go with the 225-70 or 75 x 15 LR D Goodyear Marathons with all metal stems, balanced with TST TPMS 507 Flow thru sensors installed.

Hi Old Coot, I've read that the Marathons aren't any good anymore? (Made in China?) I got the impression I should avoid them, but the posts I was reading were from 2012 and 2013, do you know if the tires are better now?

Would it be safe to assume I would need to change my rims to switch to 225s? (Sorry I know next to nothing about tires!)

I went and measured my rims tonight, they are 5 lug, 2-5/8" between them, the tires are Carlisle Radial Trail, ST205/75/15. Any chance someone knows what pressure they should be inflated to? (They all look low, but I didn't check the pressure today.)

On my last trailer I originally had Maxxis tires. I forget the size but I think they were 225/75/15 load rating D. I replaced them with the same. The reason I replaced them is age. They were 7 years old. Maxxis makes some nice tires. I never had one issue with them. They only make the one trailer tire. It's ST8008. Jerry

As for the TPMS, TST makes a good one. Check Amazon. EEZTire has a 4 sensor system for $269 also on Amazon. My buddy just bought it but has not used it yet. It also has good reviews. Jerry

Good Info on Trailer Tires

The best discussion I have seen recently on tires for use on towables is at: Trailer Towing – ST Tires vs. LT Tires | RV 101® your education source for RV information

Give it a shot and see what you think.
