Do wide base tires need heavier axles or hubs?

I recently put wide base on my trailer and ever since I did,it is apparent to me that the hub is literally bending during sharp turns. Do I possibly need a heavy duty axle to withstand the extra sideways force? My intention was to improve mileage but I think I messed up buying continentals instead of michelins. The continentals run much hotter than my x ones on the truck. ( should have done my homework)

Answer this question I have this problem too

Is this a good question?

From the tire manufacturer point of view, both previous posters have given you accurate guidance. The effect of 2" outset rims has been well documented by Axle and Bearing Manufacturers. That being said, many operators are using those same outset wheels today without major complaints. Otherwise, if you have fitted zero offset rims to the trailer, there may be another issue at hand.

With regard to the heat issue: You compared the heat being generated by the X-Ones on the drive axles to the HTL1s on the trailer axles. You may be seeing the effect of lateral drag at the trailer axle compared to the reduced drag affecting the drive axle. Consider the sideward force applied to all trailer tires during turns. Trailer axles have the ability to pivot on a much tighter arc than compared to drive axles. So another question might be your typical operating environment such as tight turns, etc.

Brandtons is also correct with regard to the rolling resistance of tires; tires with better Rolling Resistance tend to generate less heat. As already mentioned there are several calculators out there on the Internet. But if you were to compare the Rolling Resistance of the HTL1 to the vast majority of 445/50R22.5 Drive tires (like the X-Ones you are running), you would see that the HTL1 is more fuel efficient through better Rolling Resistance. All this being put together, I do not believe that the residual heat you have noticed is being generated by the Continental HTL1.

Continental takes great pride in our Customer Service operations. We would really like the opportunity to work with you hands-on to determine the issue and get the maximum value from your tires. If you get a chance please give us a call at (800) 726-7113 for assistance. We'd be glad to help.

My question to determine what is going on is... did you get an outset wide based wheel or a 0" outset wheel? When many go with a 1" or 2" outset wheel, they have the issues you describe.

Offset is the BIG question to answer. You may also, if you got the 2" offset rim, turn the rim around and bolt it on "backwards" and it gives you less of an offset.

When turning, the pivot point is between the two axles so the tires on one axle are being pushed one way while the tires on the other axle are being pushed the other way. That is something you may be seeing.

Also, check the rolling resistance on the tires. You can go to LetsTruck.com and click on tool box and there is a rolling resistance calculator on there and you can find out if you'll save any money by switching tires at this point.
