Question - Distributed weight on Camper Tires

Click For Summary

Discussion Overview

The discussion centers around the distribution of weight on camper tires, specifically in the scenario of a flat tire on a dual axle trailer. Participants explore the implications of weight distribution among the remaining tires and the potential effects on handling and safety.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether the remaining tire on the flat side would support the full weight of that side (1,800 lbs.) or if the weight would be redistributed among the three remaining tires (1,200 lbs. each).
  • Another participant references a common belief in travel trailer forums that the remaining tire on the flat side carries the full weight of that side of the trailer, raising concerns about exceeding the tire's Load Range.
  • One participant speculates that during uniform straight travel, the single tire might support less than half but possibly more than a third of the weight, with increased stress during turns.
  • A different viewpoint suggests that while a dual axle provides an advantage in safety when experiencing a flat, the stress on tires is significantly influenced by speed and loading conditions, with implications for insurance and warranty coverage.

Areas of Agreement / Disagreement

Participants express differing views on how weight is distributed when one tire goes flat, with no consensus reached on the exact mechanics or implications of the situation.

Contextual Notes

Participants rely on personal intuition and anecdotal evidence rather than technical analysis, leading to uncertainty in the claims made about weight distribution and handling.

Who May Find This Useful

Individuals interested in camper safety, weight distribution, and tire management, particularly those who own dual axle trailers or are considering the implications of tire failure while traveling.

Let say I have a 4,000 lb. camper with two axles (four tires). There is 400 lbs. of tongue weight on the hitch which would leave the remaining 3,600 lbs. distributed to the four tires (900 lbs./tire). To keep it simple, let's say the weight of the camper is distributed equally left and right. Now my question is; if one of the tires goes flat, (1) will the tire remaining on the flat side now be also supporting the weight of the flat tire (for a total of 1,800 lbs.), or (2) will the 900 lbs. from the flat tire be distributed to the remaining three tires so that each tire is now supporting 1,200 lbs.? Looking forward to your input. I hope I picked the correct forum and level. Thanks in advance. Larry

What do you think and why?
 
On a travel trailer forum, it's generally stated that if you have a flat tire on a dual axle trailer, the remaining tire on that side will carry the full weight of that side of the trailer. The issue is if you drive on that single tire on the flat side, how much weight is on that tire so you can know if you are exceeding the tire's Load Range. I have no reason to back up what I think but I'm thinking why wouldn't the three remaining tires act like a tri-pod with the weight spread equally. Larry
 
based on just intuition / personal opinion as opposed to any technical analysis of the situation, I'd say that in uniform straight travel the single tire would likely support less than half but possibly more than 1/3rd of the weight. The real problem would be when turning into the side with the single tire, in which case that tire would likely take more than half of the vehicle's weight, creating quite a problematic situation.

Your dual axel gives you a massive advantage for getting somewhere safe when you have a flat. The stress on tyres depends quite a lot on speed so I would perhaps risk carrying on my journey very slowly for a short way. The best solution would of course depend on the exact circumstances but if the trailer is fully loaded you are clearly exceeding its specified load and you are on your own as far as Insurance and warrantee conditions are concerned. I agree with phinds and his estimation of probable load (cornering will make things much worse).
