Expert Answers about Chevrolet Trailer Tires and Wheels


  • Are The Trailer Tire And Wheel Combination Balanced
  • The trailer tire and wheel combination is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. I would recommend to balance the tire and wheel combination at a local...

  • Needing a Trailer Tire That Can Handle a Long Trip at 60 to 65 MPH
  • The Kenda 8 inch Tire and Wheel, # AM30153, that you referenced can travel at max speed of 65 mph. This wheel and tire has a 4 on 4 inch bolt pattern and can carry its maximum load of 1,075 lbs at 100 psi. The tire has a bias construction and an 8 ply rating. If your trailer and boat fall under these weight capacities and the bolt pattern is the same, then this wheel and tire will work for your trip with your jon boat. If you have the clearance on your trailer, I recommend upgrading to...

  • Can Tire and Aluminum Wheel Combo # LH84VR Handle a Boat that Weighs 8,000 Pounds
  • A trailer tire that is 215/75-14, will actually fit a range of wheel widths. It will fit a 5-1/2, 6, 6-1/2, and 7 inch wide wheel. Since the tire is designed to fit this range, including the 5-1/2 inch wide wheel that comes with Tire and Wheel Combo, # AM32195, it will be safe. The tire and wheel combo you have referenced, # LH84VR, is a 205/75-14 size. The tire has a capacity of 1,870 pounds at 50 psi. To reach 8,000 pounds, you would need 6 of these tires and wheels. If your boat trailer...

  • Trailer Tires and Wheels for a 6,700 Pound Trailer
  • To reach a capacity of 6,700 pounds you would need to go with a 16x6.5 Aluminum wheel like # AM22658HWTB. This wheel has a capacity of 3,580 pounds. You will need to have trailer wheels and tires that meet or exceed the gross trailer weight. The system can only carry as much weight as the lowest rated component. You could then add tire # AM10295 which is rated for 3,640 pounds at 95 psi. I have included a link to our trailer tire FAQ article for you. If the trailer has 2 axles for a total...

  • How to Select 5th Wheel Trailer Tire Capacity Based on Trailer GVWR
  • When it is time to select new tires for your 5th wheel camper trailer you will want to start with the trailer's gross vehicle weight rating, or GVWR, which is the very most the trailer can weigh. This weight figure should then be divided by the number of tires on the trailer, 4 for a tandem axle trailer, for example. So, if you had a tandem trailer rated for 8000-lbs GVWR each of the tires should be rated for no less than 2000-lbs. In the most popular trailer wheel/tire size, ST205/75-15...

  • Is the Kenda Wheel and Tire # AM30040 Rated Per Wheel or by Axle
  • The tire and wheel capacity for the Kenda 4.80/4.00-8 Bias Trailer Tire with 8 inch White Wheel # AM30040 that you referenced is rated for the individual tire and wheel, not per axle (2 wheels and tires). You should note that the wheel capacity is 910 lbs and the tire capacity 745 lbs at 90 psi. This means a couple things. First, your towing setup is always limited to the lowest rated component in the setup, so in this situation the tire is rated lower than the wheel so the overall capacity...

  • Factors to Consider When Increasing Wheels on a Trailer from 8 Inches to 13 Inches
  • The factors that you will want to consider when increasing your tire size are wheel bolt pattern, tire width, tire clearance and overall trailer height. You will want to keep the same bolt pattern as your current tires. The Kenda Loadstar ST175/80D13 Tire, # AM3S130, that you referenced has the same 4 on 4 bolt pattern as your current tires so that will work. The next thing to check is your tire width, or section width. Increasing the wheel size may increase the section width of the...

  • What is the Backspacing of Trailer Tire and Wheel Combo # AM3S030
  • The wheel included with tire and wheel combo # AM3S030 has a zero offset which means that the mounting surface at the center of the wheel is in the middle and not closer or further away from the trailer. The wheel is approximately 5-1/2 inches wide overall which means the backspacing of the wheel by itself is 2-3/4 inches. The tire is wider though at 6.6 inches so with the tire included from the mounting surface of the wheel to the inside edge of the tire is 3.3 inches.

  • Trailer Tire Speed and Weight Ratings
  • Trailer tire speed ratings do use a letter code system. A tire rated L for speed means it can be operated up to 75 mph; a tire rated M for speed can be operated up to 81 mph. There are many other speed codes. A trailer tire that does NOT indicate any specific speed rating on its sidewall should be presumed to be rated for 65 mph. If your tires do not indicate a speed rating that is molded right into the tire's sidewall then you should go by what the trailer documentation says. It is possible...

  • How to Determine Total Weight Carrying Capacity of Trailer Tires
  • When a trailer wheel/tire like the bias ply Kenda # AM30120 shows a weight carrying capacity of 910-lbs, which is for Load Range C, that is for just the one wheel/tire. So, yes, you would double that to determine the total weight capacity of the axle/hub/wheel/tire system. Do note that if one of the items in this system is rated lower than the others, then that lower rating becomes the overall capacity limit. For example, if a wheel has a rating of 1250-lbs but the tire mounted on that...

  • Benefit of Changing 5th Wheel Trailer Tires from Load Range C to Load Range E
  • Thank you for the photo of your Rockwood Signature 5th wheel. You can change your 5th wheel's ST225/75R/15 Load Range C radial tires to a higher Load Range (D or E) if you like but this will not necessarily increase the trailer's gross weight rating unless the tires are the lowest-rated component. Moving to a higher-capacity tire can reduce the tires' operating temperature and this can be beneficial since heat is a trailer tire's worst enemy. You will want to ensure your spare is the...

  • Factors to Consider When Adding Larger Tires and Wheels to a Trailer
  • You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside wall of the tire to the trailer wall/frame. The next factor that you will want to consider is the bolt pattern of the wheel. If your current wheels have a 4 on 4 inch bolt pattern, then the new wheels must have a 4 on 4 inch bolt pattern as...

  • What is Correct Modern Tire Size Equivalent to ST78-13 Trailer Tire
  • Trailer tires of the ST78-13 size have not been in common use for several decades but when they were made their actual widths were not standardized the way tire sizes are today. There were in fact 4 different widths made with this same designation; the variants had a letter code, A, B, C, or D, as a prefix to the size. A and B versions were slightly narrower than the C and D versions. An A78-13 and B78-13 tire both most closely match the modern metric size 175/80-13 while the C and D are...

  • Tire and Wheel Combinations Weight Capacity and Tire Pressure the Same as Trailer Tire # AM10295
  • The # AM10295 tire was designed for an 8 lug wheel, but will also fit a 6 lug wheel. This will change the weight capacity of the tire and wheel combination to the lowest rated item in the setup, but the recommended tire pressure of the tire will remain the same. What you will want to do is to make sure that the valve stem used in the setup is a metal 100+psi valve stem like # AM20906. The # AM32739 and the # AM32764 tire and wheel combinations will all have the maximum load of 3,640lbs...

  • Do the Loadstar ST175/80D13 Bias Trailer Tire with 13 inch Wheel, part # AM31233, Come Balanced
  • The Loadstar ST175/80D13 Bias Trailer Tire with 13 inch White Wheel, part # AM31233, is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. It would be a good idea to...

  • Why are Manufacturer Tire Capacities Rated Lower than Fifth Wheel Trailer Load
  • Weight distribution for trailer tires, and especially fifth wheel tires, works a little bit differently than with a traditional vehicle. Because about 15%-20% of your trailer weight is (usually) on your hitch with a fifth wheel trailer, trailer tires don't have to support the entire load on their own. Because of this, it's actually quite common for manufacturers to install tires of a lower load range on fifth wheel trailers. There are also several factors that could cause tire failure...

  • Difference In Diameter Between an 8 Inch Wheel with Tire and a 15 Inch Wheel with Tire
  • The height difference between an 8 inch wheel with tire and a 15 inch wheel with tire will really depend on the tire size on the wheel. It is true that an 8 inch wheel is 3-1/2 inches smaller in diameter than a 15 inch wheel, but with tires on the wheels the difference will likely be greater than 3-1/2 inches. For example, the Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Inch Wheel # AM30040 when inflated has a diameter of 16.1 inches, while the Kenda ST205/75-15 Radial Trailer Tire with...
