Trailer tires for 2007 SuperAir 210

[gvaldez3]

I seem to have had a lot of blow outs this summer. After checking the pressure, had another blow out and another tire has a bulge on the side. The tires are rated for 1870 lb at 50 psi and boat weights about 4000 lbs not including the trailer. Any ideas?

It was in the high 90's at the time of the blowout

Thanks for any help, again

I take it your tires are 205/75/15s? What brand and what pressure have you been running them? It does sound like you have some defected tires. Make sure you are not filling them too much above 50 psi and then backing down.

various brands of 205/75/15s have blown out, I normally have the pressure at 50 psi or just below. I was wondering if I needed higher rated tires or something. Thanks rbalan

Tires that are blowing are new tires? If not what are the dates on the tires. Every time I buy a boat or any trailer I figure in replacing tires. Discount Tire and get the certificates on them. We travel many miles in the summer visiting lakes.

I'm going to make a few assumptions here since you didn't say, but I would guess your tires are original which means they are about 6-7 years old. That is about the lifespan on trailer tires from what I've seen and experienced. I would also assume you have a dual axle trailer which means you have 215/75/14 tires based on your earlier weight rating. Unfortunately with a 14" wheel a "C" load rated tire is about all you can get I think, but 4 tires will be right at 7500 lbs so I think you would be okay as long as the tires are good and properly inflated. If you are worried about load ratings measure to see if you can fit 15" wheels and tires. If so, move to a 205/75/15 "D" load rating which will get you 2150 lbs/tire. There will be added cost in wheels as well as tires going that route though.

I had 2 tires bulged at the sidewalls and low pressure was the culprit. If this is what your tires are doing I would recommend going to 55psi and checking it every time you tow. Replace all 4 tires with new (of the same manufacture date). I would recommend the Maxxis ST8008 as that is what I've moved too from Goodyear and have no complaints in 3 seasons now. My tire guy recommended Maxxis to me after I came looking for Carlisle tires. I also moved from a "D" to "E" load rating as I only have a single axle trailer and it has made all the difference I think as "D" rated tires are on the fence of being overloaded with my boat.

Thanks guys. Yes the tire that blew out was an orignal, I checked the date and it was made the 24th week of 2006. The last number after the "DOT" was 2406. My record keeping is not normally great, so maybe I've been losing the old tires. I'll go with the 14 inch tires and maybe go with the recommendations above. thanks again.

I highly recommend running all metal valve stem. Over time the rubber stems will break down and leak which causes reduced tire pressure. When a tire runs low it quickly generates heat and will self destruct from the inside out. This is case with D rated tires with a very stiff sidewall profile. I would also check to make sure you don't have a brake that is dragging as a wheel with this issue can build heat quickly in the tire not to mention the hub and fail quickly.

Kumho tires makes a trailer tire in a 14" rim that is load range D. No sure the tire size will work for your application? Might be worth a look?

There was a recent thread on the Malibu forum with a maxxis tire blowing out.
