Maxxis Tires

Has anyone had problems with Maxxis M8008 tires? I just baught a 1996 Carri-Lite Emerald series 5th wheel. It has been sitting for several years, and the tires need to be replaced. It has ST225 75R 15 size tires.
in some of the threads I've seen that people have had problems with Goodyear and Carlisle. What about maxxis M8008 tires? I would like to go with a E side wall D's are on the 5er now. and are Radial tires better than bias?

IMHO 15 inch tires are probably under rated for that heavy of an trailer. Look on the left front corner for the ratings tag. It will tell you the axle ratings and the fivers GVWR. From this you can make an educated guess as to what tires ratings you need. Personally I would dump the 15 inch and go to 16 inch Michelin XPS Rib or BF Goodrich commercial TA and be done with with your worries.

Maxxis tires ( http://www.maxxis.com/Industrial/Tra...ST-Radial.aspx) are getting very good reviews on all of the forums I visit. If you do decide to go to a larger (16") tire make sure you have clearance between axles to do so (1" minimum).

In addition to the "standard" LT235/85R-16E Michelin XPS Rib that has a load rating of 3042 lbs @ 80 PSIG with a 32.0" diameter, there is also a LT245/75R-16E XPS Rib available with the same 3042 lbs @ 80 PSIG load rating and a diameter of only 30.6". If that's still too large, there is a LT225/75R-16E XPS Rib available with a 2680 lbs @ 80 PSIG load rating and a 29.4" diameter. One of these should work as a replacement for most 15" tires used under 5th wheel RVs.

If your trailer is like mine and does not have the clearance for larger tires/wheels and you have to stay with the 15's, I use Cooper ST tires in the D load range with excellent results. The Maxxis has been getting good ratings also on every forum I look at.

My GAWR is 5200 Front and Rear.
The GVWR is 12,660
The Trailer dry weight is 9,080
The tag says to run ST225/75R 15 D with 65 psi.
I have 2.5 inches of clearance between the tire and the trailer and 5 inches between the tires.
I wouldn't think I have the room to go any bigger. When I load the 5er would that 2.5 inches of clearance shrink with the extra weight?

There is a little problem with your figures. The ST225/75R15D is only rated at 2540# which would be under your axle’s 5200# rating. Any RV trailer manufacturer providing those tires on those axles would be subject to severe penalties from the DOT. Even if the axles have a 5000# rating the tires would be just marginal at best.

Your best option (money wise) would be to go to the ST225/75R15E tire. It is the same size and it will give you the added load carrying ability you need (2830# @ 80 psi) without having to change rims. Make sure the rims will work though as lots of 15” OE rims are only rated for 75 psi and you will need the entire 80 psi.

In 1996 is was quite common for Carriage and most other manufacturers to use 15 inch tires under all of their products. It does not make it right. had a friend that had a carriage and was a full timer. They blew on average of 3 tires a year on that over loaded fivers poor suspension. The last one totaled their truck and trailer for them. Personally I would upgrade the axles to 6000 pound, install 16 inch LT tires and wheels and move on.

Our Gulfstream came with Carlisle JUNK on it, they lasted less than 1,000 (no typo thats 1 K) miles, 3 of the 4 failed one exploded...

after much research i made the move to the E rated Maxxis 8008 tire, so far im loving them, 2 long trips in the summer heat with no problems, i think most agree that at this time they are the best solution for 15" wheels.

The first trailer I every had came with Carlisle bias ply tires, 2 of them separated as if they were recaps, that was about 500 miles on them. i had to replace all 5 with somthing else. They also ripped up a brand new trialer busting thru the wheel well and into the kitchen. It cost $1200 for the repairs. Carlisle Tires did pay for the damage and Thor industries sent me 5 new Steel belted radial (goodyear) tires for the trailer. The Maxxis tires are pretty good. THey were onmy second trailer and lasted 4 years before trading it in.
