Expert Answers about Tires and Wheels

• Recommended Air Pressure Be For a Single Axle Trailer With a 1000 Pound Load
• The tire you reference, Kenda # AM30620, has a 990 lb maximum load with a psi rating of 90. Carrying a 1000 lb load will not be an issue because the capacity with these tires is 990 for each tire which gives tallies a total capacity of 1980 lbs. You will want to keep these tires inflated to the maximum psi of 90 rating. By having the tires fully inflated, they will perform and wear better as well as give you better gas mileage. To find the psi rating, it is stamped on the sidewall of the

• What Will Cause Excessive Wear on the Outside of the Tire on a Single Axle Cargo Trailer
• Since your trailer has been over its weight capacity most likely the problems you are experiencing with your tires are directly related to this. I would recommend getting the weight of the trailer under the capacity and then check the suspension components to make sure there is no damage. A problem that arises from an overloaded trailer with a suspension issue is the uneven wearing of the tires on the outside. Because of the overload, your suspension components may be excessively worn allowin

• 4.80-12 Trailer Tires Keep Blowing Out on 2000 Coachman Camper Trailer
• Trailer tires are made with a thicker side wall than passenger car tires. Because of the thicker side wall they generate more heat. If they are under inflated and/or overloaded, that generates even more heat and can cause the tire to fail. Always inflate trailer tires to the maximum psi rating as indicated on the tire. If a tire sits long enough, it can suffer from dry rot or environmental wear unless covered when not in use. Given the area you travel in this could also be a factor. You will

• Improving Tire to Fender Clearance So Fenders Will Not Cut Tires
• Looking at your photo, my suspicion is that at some time the the tire and wheel size of that trailer was changed from the stock size. If the stock size is known, returning to that size would fix your clearance problems. Changing to a narrower wheel/tire might help, but from the photo you provided it looks like the wheel/tire combo you are using is too tall, so going down to a 14 inch wheel might not be a bad idea. I would recommend going with a 14 inch wheel like part # AM22328 with a radi

• New Trailer Tires Appear Deformed
• When trailer tires leave the manufacturer, they are palletized. When they are placed on the pallet, the tires are compressed in order to save space and reduce shipping costs, as you can see in the provided photo. Although they might look a bit alarming, there is actually nothing whatsoever wrong with the tires. Once mounted on rims and inflated, they will be perfectly safe and will preform very well for you. We sell hundreds of trailer tires on a weekly basis, and this has never presented a p

• Diagnosing Cause of Uneven Tire Wear
• Typically, when a tire displays excessive wear on the inside of the tread (closest to the trailer), it means that the trailer is consistently being overloaded. When the trailer carries more weight than the axle is rated for, the trailer wheels can bow as shown in the diagram I provided. Broken or excessively worn suspension components can cause this as well. Examine the components like the leaf springs and shackle links and replace if necessary. You will also want to make sure that your ti

• Troubleshooting Uneven Tire Wear and How to Pick Out Replacement Trailer Hubs Shorelander Boat
• In order to pick out the correct replacement hub you will need to remove the hub and get the numbers that are stamped on the bearings. You will also need to know the bolt pattern of the hubs. I attached an FAQ article on how to determine this. Since you have movement on your hub assembly you most likely have damage on the bearing/hub/spindle. Typically, when tires wear on the outsides it is because they are under-inflated. You always want to inflate your trailer tires to the maximum psi liste

• Trailer Tires Wear Out on the Center Tread on a Rally Wagon Trailer Towed Behind a Motorcycle
• First of all, the trailer tires that we carry are rated for a maximum of 65 miles per hour unless otherwise noted on the tire sidewall. Going faster than this will cause rapid heat build up in a trailer tire (which has a thicker sidewall) and can lead to failure. When tires wear out in the middle that means that they are over inflated. You can try taking out about 5 psi or so until you get even tread wear. If a tire is inflated to the max psi, it should not wear unevenly. You may want to che

• Causes of Uneven Trailer Tire Wear
• Do you mean that the inside of the tread (the half closest to the trailer) is wearing unevenly? Or are you speaking of the inside sidewall? Many things can cause uneven tire wear, including a bent axle, an overloaded trailer and worn or broken suspension components. A trailer axle should be slightly arched, with the high spot in the center of the trailer and the spindles on either end being slightly lower. When the trailer is loaded the arch will flatten, placing the trailer tire treads in

• Troubleshooting Lug Nuts or Wheel Bolts Not Threading On To Hub With Kenda Tire and Wheel # AM31206
• The Kenda KR25 Tire and Wheel, # AM31206, is designed to work with bulge style lug nuts 1/2 inch - 20 threads per inch like part # AM90054. The bolt holes on the wheel will have a 60 degree angle that this lug nut will fit into to tighten onto the wheel stud. If you are using a lug nut similar to part # X1023R, we have experienced problems with this style of nut not fully threading onto the stud because there is not a bulge seat at the 60 degree angle and the hex portion begins to strip and

• Tire Sidewalls are Cracking on Kenda ST205/75D14 Bias Trailer Tires # AM1ST84
• I actually have this same problem, though it is occurring on my car and not a trailer. I spoke to our resident tire expert and he stated that this happens from the UV rays in the sun. It is not an immediate concern unless your tires are losing air pressure. If this happens they will need to be replaced. If the tires do need to be replaced at some point, I also recommend cleaning out the wheels where the tires normally cover them. Gunk can build up in there and also cause tire pressure loss. I

• Trailer Tires are Wearing On the Inside Tread with Low Miles on the Tires
• You may be experiencing some wear in the suspension components that can cause tire wear and also be a symptom or cause the axle to be misaligned. Inspect your suspension components and if any of the holes where hardware goes is egg-shaped, that indicates wear. To determine if the axle is not properly aligned, pull in straight on a level surface and stop. Measure from the center of the axle on one end to the center of the ball hole on the coupler. Then do the same on the other side. Even a sma

• Will Bias Ply Trailer Tire Sidewalls Flex Less than Radial and Help With Snowmobile Trailer Sway
• Snowmobile trailers are notorious for having sway problems due to their short lengths and wide construction. this makes it hard to load the trailer with enough tongue weight to eliminate trailer sway, especially at higher speeds. The best prevention against trailer sway is proper trailer loading. Going with a bias ply ST rated trailer tire may help a bit because the tire construction is inline with the tires direction of travel and the radial tires construction is across the direction of trav

• Cause of Tires Wearing on Inside of Snowmobile Trailer
• There could be a few things that are causing your trailer tires to wear on the inside. It could be that at one time the trailer was overloaded and the axle has been slightly bent down. Another possibility is that the another part of the suspension is worn out. You will want to check over the suspension components, and make sure that none of the bolts have made oval holes where they are connected. This could indicate that these parts will need to be replaced and are worn. You will also

• What Makes Trailer Tires Wear on the Inside Only and Can 175/80-13 be Replaced With 185/80-13
• There are a couple of things that can lead to the tires wearing on the inside only. Basically what is happening is the top of the tire is leaning in towards the trailer causing most of the weight to ride on the inside. This pretty much means the axle is bent, especially if both sides have the same problem. If it were just one side, there is a chance that is just the spindle that is bent. It will keep wearing on the inside until the issue is resolved and that could mean a new axle. You could p

• Trailer Tire Blow Outs on a 2007 Carriage Cameo 5th Wheel Trailer
• What probably occurred was excessive heat build up like you have said. Trailer tires are made with a thicker side wall. This thicker side wall is made to handle more vertical load associated with trailers. If a tire is under inflated, this will allow for excessive heat to build up and the tire will not be able to cool down like normal. This is when you get blowouts. The solution is easy. Make sure that you inflate the tires to the maximum psi rating as indicated on the tire. For the Karrier S

• What Can Cause Frequent Trailer Tire Blow Outs
• A lot of trailer tire blowouts are a result of heat build up that causes the tire to fail. There are several things that can cause too much heat to build up but the main two most likely suspects are overloading the trailer and/or under inflated tires. The trailer axle capacity should be located on a sticker or plate on the frame. Avoid loading the trailer beyond its capacity and use tires with an appropriate weight carrying capacity. Trailer tires should always be inflated to the maximum psi

• Troubleshooting Tire Problems on a Heritage Boat Trailer with 2005 Crownline 240 EX
• I would start troubleshooting with the capacity of your trailer axles and the total weight of your boat, trailer and contents when loaded and ready to travel. Make sure the fuel is topped off and all your normal contents are in the boat. Take the loaded rig to a local scale and have it weighed. When weighing, unhitch the boat trailer on the scale and make sure the vehicle is pulled off of the scale. Once you have the loaded weight of the boat you can verify that the trailer axle capacities ar

• Troubleshooting a Bouncing Boat Trailer, Possible Causes and Solutions
• It sounds like a problem with tongue weight. In this case, the tongue weight may be too high meaning too much weight is forward of the trailer axle, pushing down on the hitch, or too low. If at all possible, try moving some weight further back or forward. If you have a large motor on the back, it could be making the tongue weight too low, while gear at the front or items mounted to the trailer tongue area can make it too high. Also, most trailer tires are rated for a maximum speed of 65 miles

• Can Changing From Bias Ply to Radial Trailer Tires Contribute to Trailer Sway
• There can be many factors that lead to trailer sway. In this case, the new tires have a lower load rating. If they are being overloaded, that could cause some problems. You will also want to make sure they are inflated to their maximum rated psi as indicated on the tire sidewall. Radial tires trend to track better than bias ply tires so I do not think the different style is leading to the problem. If the tires are a different size than what was on the trailer, that could lead to a difference

• Causes of Trailer Tires Wearing In Center On My Triple Dexter Axle Car Hauler
• If any of the components were bent or damaged there is a chance that the bent parts could be causing the irregular tire wear that you are seeing. If a component was bent you would usually see tire wear on the inside or the outside of the tire depending on which way the part is bent. More than likely the tire wear is being caused by the amount of air in the tires. If the tires are over inflated, then typically you would see more wear in the center of the tires. If the tires are under inflated,

• How to Correct Trailer Sway when Towing an ATV Trailer
• Trailer sway or whipping is normally caused by a low tongue weight condition due to improper trailer loading. Proper tongue weight is the best defense against trailer sway. For your ATV trailer you should have at least 10 percent of the total trailer weight on the tongue of the trailer, this means that there should be more weight loaded in front of the trailer axle or axles than behind them. We have an informational article for you to review, see link, that explains tongue weight and how to

• Recommendation for Eliminating Premature Tire Failures on a 28 foot Holiday Rambler Travel Trailer
• I am curious about the type of tire the 225/75-R15 is on your 28 foot Holiday Rambler. If it is not an ST rated tire that is most likely the reason for the premature failure. The ST (Special Trailer) tires, like the Karrier ST235/85R16, item # AM32764, have a thicker side wall for handling the vertical load that is required on trailer axles and will last longer than a passenger rated tire like an LT in a trailer towing situation. You should also make sure the load rating of the tire matche

• Troubleshooting Trailer Tires Wearing Out on the Outside Treads
• The wear is going to be the same with a bias tire or with a radial tire so changing out the style will not help with what is causing the wear. If the tires were over inflated, the center treads would wear. Under inflated tires would show wear on the inside and outside treads. If the wear is just on the outside then the tire is riding at a slight angle with the bottom pointed more in toward the trailer than the top. You will need to check the suspension components, axles, spindles, to make not

• Why Do I Have Flat Spots on the Tires of My 26 Foot Coachman Travel Trailer
• The tire problem that you have described will cause you several issues. First of all, while traveling, you will notice a sort of wobbly ride and hear a distinctive WHOMP WHOMP WHOMP as you roll down the road. First it will only be noticeable at slower speeds, then all the time. You will also experience a shaking or vibrating steering wheel. The wobbliness, the WHOMP WHOMP, and the vibrations are more or less just annoying. To me, that is reason enough to change the tires asap. But there i
