Is it necessary to only by tires for T.T. Why can't I not buy regular tires for my T.T? Reason I am asking is that its seams that I am getting flat tires too often, 2 in one year. is that normal? This tires are fill with nitro air which I fill they are full of it. you get my drift.Thank you in advance..

The tires you put on your trailer MUST be rated to carry the GVWR (gross vehicle weight rating) of you trailer.You should not use "regular" passenger tires on your trailer.I doubt you can find LT (light truck) tires in the size (I'm guessing 14 or 15 inch wheels - probably ST205/75D14 ) that are on your trailer....so you will have to stick with ST tires.Most all ST tires are made in China and have a shaky reputation.Many of us have had good luck with Maxxis 8008 tires.and yes...nitrogen is pretty much of a hype.

You can't and should never use passenger car tires on your RV!Try some Maxxis tires like suggested and don't worry about filling them with anything than plain old air.

No to anything other than the original ST tires or LT tires along with appropriate rims. You might want to go up one load rating (LRC to LRD) and use better quality tires.Most travel trailers come with ST trailer tires and it is critical to stay under 65mph and to keep them inflated to the correct psi at all times. Ignoring either causes overheating of the internal tire structure, irreversible damage and will result in tire failure. Avoid potholes. Stay off shoulders where you could pick up something that will cause a puncture. What is the weight of your TT versus the total tire load rating? You want a 20 percent or more safety margin but some manufacturers load them up close to their rating. The weight can vary from side to side too which can unknowingly overload tires on one side.Are you having punctures, "blowouts" or tread separation? In the occasional case, the axles can be bent (owner caused) or misaligned (factory caused) causing uneven tire wear and eventual failure.Many RV owners use a TPMS to monitor tire pressure in their RV. Some (like me) check tire pressure on each leg of a trip before heading off. We have made in China Goodyear Marathon load range "D" tires with 10,000+ miles on them over 2 season with no problems - factory normally installs ChinaMaster LRC tires.Lots of excellent reading on this blog by a former tire engineer.

There's more info on this and other forums about tires than you can read in a day; just search on "tires" and you'll be overwhelmed. Briefly stated, some heavier FWs are coming from the factory now with LT tires. But, unless you have 15 or 16" wheels now, you may not find an LT tire in your size, or you may not have space to go to a larger wheel and tire. The alternative is to get the best ST tires, which most people believe are Maxxis. OTOH, they too can blowout. Treat your ST tires well: don't hit curbs, keep them at max PSI all the time, don't bother with nitrogen (sales gimmick), don't go more than the speed rating (usually 65mph) and expect they may not last more than three years.

What is flattening your tires? Nails, screws, or what?I have good luck running E rated tires. I've had tires delaminate over the years and several trailers, but no flats or blowouts.

I simply do not have enough space (clearance) to upsize to a 15" rim. Any and all help and guidance would be truly invaluable.

Many thanks

How much clearance do you have now?

Most TTs use off the shelf components. That means that their clearance between the tires are pretty much the same. This is a good thing as that is the most limiting factor in an upsize. Most TTs with 14" rims can easily do 15s... I ended up with 16s on a TT that started out with 14s... That was close to the limit, but it worked fine
Wheel well clearance is the other limiting factor, but it is pretty easy to improve upon.

And to date, knock on wood, I haven't had a blow out with ST tires.

I disagree.... I have 14 inch wheels and found a better rated LT tire..
however.. the op's tire size is still unknown at this time..

If the op would kindly post his tire size and TT gross weight we might better advise him.

TexasChaps The size for my T.T tires are 205/75R14
However the sticker on the outside of the unit says GVWR 7,620LBS, and the sticker inside of the manual says GWVR 6,000LBS which one is correct?

I would opt for the sticker on the unit. A GVWR of 7620lbs minus the hitch weight ( say 750lbs ) gives you 6870lbs on your tires so you most likely have 3500lb tandem axles. 14 inch tires typically come in load range C or D at best, load C is 1760lbs ( 4x = 7040 ) and is what the TT most likely came with as it's the least expensive option and has practically no safety margin. ( a few percent at best )
Load D is 2270lbs so 4x = 9080lbs.. ( around 30 percent margin )
Without starting another ST/LT tire war, I would suggest a load D LT and there are very few of them at 14inch size unfortunatley.. I personally have no faith whatsoever in ST tires and have always used LT's.. ( and coincidentally never had a blowout.. ) as long as the rating is greater than your max load and they have a bias ply type tread you will be ok.. I have used the Maxxis ue168n bravo truck tire for many years with no issues. Part # is: TL12458000, size:205R14C, service rating:109/107Q, and load capacity:2270lbs

On a forum like this anytime someone sez that you must do this or that you can't do dat , you probably can do dat . There are very few absolutes !
Many ST tires are rated for more than 65 MPH . Should you drive faster , probably not , but ya can if ya want !
Some manufacturers install tires other than ST tires . I delivered for many years cargo trailers that come from the factory with non ST tires .
Should you put "P" tires on your trailer , probably not as there are better alternatives , such as better brands or more ply ratings .
What ya do not want to do is get the " Tire Police " on your back as they will track ya down with dogs and let the air out of you China Bombs !

Mayby more problems with Maxis tires are seen ,because many TT makers use that brand on their TT.

ST tires are placed on TT's mostly for reason of more maximum load given for same sise ( if you can find the same sise in LT to compare!). To laws of nature though , lesser deflection is better.
this is because of the lower maximum speed of 65 m/h for wich the maximum load is calculated, more deflection is allowed.

If you would give the ST tire the same deflection a LT tire would have , longer livetinme, and lesser chanche on damage to them by overheating.

So wiht new tires you should let me calculate a saver pressure, wich is probably higher then the given AT-pressure on sidewall.
For LT tires most American tiremakers allow 10 psi above AT, and of mailcontact with Goodyear I make that they still allow it for ST, as they did before.

But if you can find a LT tire with same maximum load in a bit different sise, you automatically go from the pressurecalculation for lesser deflection.

I once made a topic about the aftermarket replacement in wich relation between speed and maximum load is explained.

According to the winnebago website, your trailer has 3500 pound axles, and a GVWR of 7000 pounds.

An example of tires that might be considered would be Hankhook RA08, in 185R-14. This tire is a higher profile ( 82 series ) "commercial" tire that has approximately the same rolling diameter as your existing 205/75-14 tire. The load rating on the Hankook is 1874 ( 3748 for the pair ), which exceeds the axle rating by 248 pounds per axle.

Another example of a potential tire is Kumho 857 in 205R-14. Again, a 82 series tire, so in a 205-14 it is slightly larger in diameter than your standard tire. It's load rating is 2271 ( 4542 for the pair ).
Both of these tires are appropriate for your rim width, have load capacities in excess of the axle capacity, and have higher speed rating than your standard fitment tires.
Both of these are load range D.

Your standard tires are likely load range C, with a load capacity of 1750 or so. You could look on your sidewall to verify that.

So when in doubt or don't have any preferences, get Maxxis 8008?

I prefer not to function that way. When in doubt, I research, until I have a preference based on more than just guessing what might or might not be best.

Search how many failures on Maxxis recently and search RECENT failures reports on the new Carlisle RH radial and post the results back on this thread.....

The blind reccommendations on Maxxis on this forum borders on the absurd.
