Tire update
Well after doing some research i have only found that most of the trailer tires even major brand are not made in the good old USA but out of the country. It also seems that the 235/80R16 is not a popular size and seems to be the problem. That doesn't leave us with much choice. Really don't want to spend 200.00 per tire.

Darrell: Check your size. Are you sure it isn't 235/85 R16? There are lots of domestic tires in the 85's.

pud2,
You don't have to stay with the 235/80R16 tires. You can change to 235/85R16 with no problem. They are only .92 inches taller than what you now have, and are the same width. There is plenty of clearance under your trailer, and between the tires. This will give you alot more options as to brand and availability.
If you do this, you will have to change all 4 and I would also change the spare.

Lonnie,
I'm confused? Why would you have to change the spare?

Brad, I would change the spare only if I were changing tire size from LT235/80R16 to LT235/85R16. My reason would be to keep all tires the same size so as to have a more harmonious outcome, in the event that I should have to put the spare on the ground and travel for any great distance.
Sorry, I should have elaborated in the last post.

Harmony is good Brad, we will have to add that to our pre-towing checklist!!! Item number 7 )Check tire harmony!! I liked that answer LonnieB, but I have to admit I have never heard it referred to in that manner. Rambling again........oh, well..........forgive me!!

Bill i did look at that option but could not find any with the correct load rating of 3500 lbs @ 80psi. All of the 235/85r16 were only 3000 lbs load @ 80psi. I don't won't to go with a lighter load on the tires as i don't think that would be a good idea. All of the tires had a E rating but not correct lbs.

Maxxis tires come in the size you need with a max load of 3420lbs @ 80PSI. It shows them as $180 each if you order directly from them but I'm pretty sure they are cheaper if you buy them from a tire dealer. I think I read on other forums that they are available at Discount Tire. They aren't made in the USA either (my 15" ones are made in Thailand and others are made in China) but I have read many good reviews about them anyway. I don't have a whole lot of miles on mine yet (about 1250) but so far so good. Here is a link to their website if you are interested: http://www.maxxis.com/products/trail...ail.asp?id=118
I hope this helps.

Darrell: Why do you want to go to 3500 lb. rating? The original Tacoma's that came on our coach are 235/85R16 and are rated at 3042 lbs. @ 80 psi. Even if you are fully loaded, like I am, and gvw is 14,400 lbs. you only have under 11,000 lbs on the trailer wheels because the hitch is taking up the load. I can speak from experience because I weigh often and especially before I leave for Tx. fully loaded.
You have the same model as I do only newer. Ours is a Big Sky which has the gel coat and believe me it is packed full. I am still around the gvw for the coach.

Brad, we discovered the hard way that having mismatched tires on an axle will throw that axle out of alignment. In our case it was a load range issue but I'd bet the size difference would do the same thing.
Darrell, the last time I bought tires for our Montana (prior Montana) I went with LT tires rather than ST. They're much easier to find if you need a replacement. And cheaper. Keystone even put LT tires on Montanas for a year or two so I don't think it would be a problem. Thi s one came with ST but when we replace it will be with LT.

Bill i want to go back with same specs. on tire because i feel they put them on there for a reason. And the other thing is if something was to happen GOD forbib i want to make sure that want be a issue that i had wrong load lbs rated tires on and i feel much better sticking with the same load rating. The other thing is if you add the 3500 lbs 4 times that equals 14,000 and if i remember the gvwr on axles is 14,400.

Pud, somewhere around 2500 lbs of that 14,400 is on the hitch. The rest is on the trailer tires. Take your rig to a scale and you'll see how this works. On mine, total weight on a scale is 14,620. Weight on the axles is 11,760. The hitch is at 2,860 pounds and that is carried by the truck axles, not the trailer axles. There is only 11,760 lbs on the trailer axles. 3042 is plenty of rating on the tires in my opinion. It never hurts to have more if that's what you want. It's just not really necessary unless it makes you more comfortable.

Steve
I understand the numbers. At 3042x4=12,168. I have a weight of 11,060 on the axles and i have 6,000 lb rated axles. I know the 3042 would be sufficient but is getting close to max rating and if more weight was to be added it would even be closer. What i don't understand is if these numbers are as is why would keystone put on a higher rated tire? The other thing is after doing research and reading on tires i understand that the ST tire is made different to withstand different loads verses the LT tire. Also after looking at the specs for a 3670 on Montana's web site it has 235/8516R size listed and they have 235/80R16 size on the sticker on my RV. Know i am REALLY GETTING CONFUSED. I know experience is a big part of making a decision on things but i also know when it comes down to a legal matter all that matters are the facts and what should have been.
