I'm in the market for new trailer tires. I've got standard Carlisles which came with the trailer, but now hear mixed reports on their durability/quality. After some research, I'm considering these: ST Radial M8008 | Maxxis Tires USA. Trailer is 16', including tongue and about 2400# dry. What are you all using and why? What are you using as a spare?

My 16SC has close to the same specs as your trailer, 16-foot length and about 2300 lbs or so dry. It had a mismatched set of tires and wagon wheels on it to get home with, one of which I have on the bumper now for a spare. The original factory tires were still with it, they were B.F. Goodrich Silvertown Customs, g-78-15. They were rated as replacing an 8.25-15 in older-size terms. The load ratings on the B.F. Goodrichs were max load of 1620 lbs, at 32 PSI. I replaced with the Maxxi 8008 8-ply. The ST205/75R15 size replaced the G-78-15 nicely. They are rated a load range "D", for 2150 lbs at 65 PSI cold. I painted up the original rims to match the trailer color, mounted the tires and added a couple caps....as you know, the caps make all the difference.... I have only towed the trailer around our block a couple times, so probably less than 10 miles altogether since they have been on, but with the weight-dist hitch and the new tires, it acts barely there.

Thanks Ten… Right now the 225/75R/15 Carlisles I have, have an inflation rating to 80psi. So far I've been successfully riding on them with no adverse events for about 5000 miles (2 years). How do I know if my rims are truly rated for 80psi and not 65 (there are 2 versions of the Maxxis at that size)? The PO of this trailer probably used whatever tires he could get his hands on with whatever rims were hanging around… he was not the most ethical chap In case you can tell by looking at it, here's a photograph of the wheel without it's rim and cap.

I would only be guessing at the rim rating. My guess would be that the rim ought to stand up to 80 PSI if you so chose to inflate the tires that much. I did some reading at the time of the choice for tires and a friend had been running Carlisles, with mixed emotions. The tires were new and good tread and all, but did not handle well on the particular trailer. If I remember rightly, his were a 4-ply rating and the trailer towed with quite a bit of sway. Replacing with the Maxxis straightened out the problems completely, and the 8-ply tires gave quite a lot better ride and response, I decided to start with the Maxxis and skip the comparison steps.
I never did tow mine on the road with the wheels that came home on it either, so I don't even have that comparison. I do know that there is not any bounce or skip in the ride with the tires inflated to 45 Lbs, and towing at unladen weight. As Spring closes in I am inclined to load 'er right up with water, propane, camp chairs, full coolers, etc, and take it for a spin on the expressway to see how the inflation affects the ride.

My trailers are smaller (about 15 feet and 1500 to 2000 lbs). I have had very good luck with bias ply trailer tires. They fit vintage wheel wells and cut outs and have a stiffer side wall. The cost is a bit higher, but it's worth it to me.

As Spring closes in I am inclined to load 'er right up with water, propane, camp chairs, full coolers, etc, and take it for a spin on the expressway to see how the inflation affects the ride. So… the lower load rating (rating D, as you call it @ 2150# each) should be more than adequate for my weight/size trailer… and on my existing rims? If I don't need to pay extra for the higher load rating Maxxis (80 psi)… I would certainly be OK with that. My main concern is switching away from the Carlisles to a better quality and more stable tire and I'm hearing very good things about Maxxis. Also… You tend to inflate them up more toward their 65 psi limit as your trailer's loaded weight increases? Thanks!

The way I understand, the higher the load, the higher the inflation should be. Makes sense, to keep the rims off the ground I guess. The "load rating" comes right from the sidewall of the tire.
I found the pair of Maxxis on eBay for about $110 a tire. The cheap-os at Tractor Supply are more than that. I have not lost any sleep over the choice.

We bought trailer tires at Costco. They are Greenball Towmaster SS Special Trailer Radial Tires ST215/75R14 LRC. They have great ratings and we found the price very good ($73 ea.). I ordered them online and they mounted them on our rims for us.

I'm definitely going with the Maxxis M8008 ST Radial Trailer Tires. My only hesitation is whether my rims are actually rated for 80PSI? I've been riding on my Carlisles which are rated to 80PSI on my current rims with no incident but with some significant air loss when the trailer is parked for long periods on jacks.
How do I know if my rims are really up to the 80PSI load? I don't see any markings, etc. that indicate. So, should I get the 65PSI or 80PSI Maxxis? The 65PSI's are load rated at 2540 lbs. each for a total of 5,080 lbs. My trailer dry weight is 2400lbs. and probably closer to 3,000 when fully loaded with gear and liquids. The 80PSI's would give about 600 lbs. more load rating and cost a few bucks more per tire. Help!

It seems that my rims have been ok with the 80psi I have on my current Carlisle tires, which I will be replacing with Maxxis; either the 65psi lower load or the 80psi higher load. I have towed about 5000 miles with the 80psi Carlisles on these rims, with no incident… although the tires do lose air when parked for long periods (about 15psi this winter). Either load rating will easily handle the loaded weight of my trailer (see above thread quote). Question: which load rating should I go with? Any advantage to having the extra load rating of the 80psi version Maxxis?

If you are using the standard pull in valve stems you may be losing air there as they aren't designed for that much pressure (80 psi). I never use above 65 psi. I would buy the metal truck valve stems made for high pressure. Also make sure that the rim isn't rusty or dirty before installing stems and mounting tires.

DO NOT BUY tires from DISCOUNT TIRE those people claim to match anyone's price but what they do not tell you is they charge a fee to mount and balance tire while all other places mount and balance free.
TWO 8 ply Tires at Firestone are $90 each free mount and balance plus 10% sales tax = $198.
TWO 8 ply tires at Discount tire $90 each mount and balance $100 plus 10% sales tax = $298.
I hate deceptive advertising.
4 car tires will cost you $200 extra at Discount tire for mount and balance.

Our radial Hartland trailer tires from Discount Tire seemed to be great for us, and good price at $55 a tire, out the door for 167 after everything including road hazard. Not sure of the brand Pepboys was gonna put in, but they were comparable and was gonna be $235 and no road hazard. And to my knowledge, both places charge a fee for the mount and balance.. Called " installation fee" I guess. They did great on our 1100 mile round trip, even at 60 + mph. Very smooth and noneventful trip, the way you want it!

My sister and her husband have a newer fifth wheel trailer. They have had a number of trailers over the years and are fairly experienced with towing. Recently they were going on a trip and had a blow out. When they went to replace the tire they were told that trailer tires that begin with "ST" have a max speed of 62 mph. They ended up replacing all four tires with truck tires. They were told they had the needed sidewall strength but could be driven at higher speeds.Has anyone else heard of this?

We're getting hamlet ready to batten down for the winter, but by spring, he will need new tires. His first set was Coker white walls, but when I thought about it, I don't know if they are trailer tires. We want to keep with white walls, anybody have any suggestions (other than painting the white walls on)?
