Location: Union, Mo | I keep blowing trailer tires. I have a 4 horse with living quarters. Full load is about 20k pounds. I'm using 12 ply, G range, 16" tires. Any suggestions without altering the axels to accommodate bigger tires. |

Location: Valentine, NE | Recently went thru this. First, make sure your at the max psi for inflation. Check to make sure trailer travels absolutely level. Make sure also, the tires are fairly "fresh"-less than 4-5 years old. Another tip is to check wear patterns. If odd, axle or bearing problems might be at fault. We priced changing to a 17.5" tire. You have to change the studs by either drilling the stud holes out than replacing the studs or replacing the drums with larger studs. This and with new rims/tires, cost wise, it took !1.5, 16" tires to pay for the swap in our area. As far as I know, this is the only feasable option. Trailer had other issues so we traded trailers to one with 17.5 tires. Might do a search on this site as it has been discussed in great detail. Good luck!

Location: Penrose, Colorado | check out Southwest wheel.com you can change to heavy duty rims that will carry 110psi and then go to a 16 ply 16" tire and get by, you have way too much trailer weight for a 10 or 12 ply tire and I would not be cheap and buy a cheap tire. |

Any suggestions without altering the axels to accommodate bigger tires. A 12 ply tire would be a load range F tire, probably a Chinese build piece.. Be sure your rims are rated for 110 psi, if so you could use a Goodyear G614RSTin a 235-85R-16 load range G 14 ply. They are rated at 3750# at 110 psi and are speed rated to 75 mph whereas the regular "ST" tires are speed rated at 65 mph.http://www.goodyearrvtires.com/tire-selector.aspx These folks have an assortment of 17.5 aluminum wheels that will work with your 9/16" studs. May want to price a set of wheels and a set of 215-75-17.5 load range H tires. I believe they would be rated at 4808# at 125 psi.http://www.trailertiresandwheels.com/17.5-Aluminum-Trailer-Wheels |

Any suggestions without altering the axels to accommodate bigger tires. Have you weighed your rig completely loaded? To determine if you are overweight on your tires? Second are your tires fully loaded to max cold pressure? Finally, are you over speeding your tire rating...ie going 75 on 65mph rated tires? |

Location: Union, Mo | Are you suggesting to fill the tires with its psi rating? For example if the tire reads 110 psi; fill it to capacity? |

| I argue with my husband and another man who is even a mechanic about this all the time. They both think it is best to not run at the max psi on the tire and say to go about 10-15 below. I think alot of people think this! |

Location: Where the wind comes sweepin' down the plain... | Maximum cold pressure is one of the things that the maximum weight rating is derived from. Goodyear used to have a chart in the RV section that would tell you for every 10 psi that you ran the tire below the max psi, then you could figure x percentage less in capacity. Other things come into play as well, speed, age, etc. |
