Maxxis Load D To E - Bouncy Ride
Had maxxis load E's mounted and balanced to replace my factory D's. TT weighs about 9500 loaded but wanted peace of mind. Drove home and ride was bouncy and I could feel it in the drivers seat. Cal...

One would think that 10 belts would be stronger, tougher and more puncher resistant than 8 belts. But, unless you are a tire designer it is hard to say.
It could be that 10 thin belts are more flexible than 8 thicker belts and run cooler.
It is anybody's guess.
All we know is tires are designed and tested or specific applications.
Actually the ST and LT tires in question all are a two ply carcass with two steel tread belts. Looking at Goodyear Marathon specs shows the 16" E is 4 lbs heavier than the same 16" size D tire.
The difference is the two plies in the E tire are stronger/heavier than the two plies in the D tire and same with D vs C and so on down the chain.
Number of ply exceptions are the Michelin Ribs and the Bridgestone R-250 are a single steel ply carcass with the usual two steel tread belts..... and some off road tires such as the BFG Mud Terrains are advertised as having three sidewall plies.
Sailun doesn't show much tech "stuff" in their website adds so I have no idea how many carcass plies they have.
When we ran the old 8 and 10 actual ply truck tires they ran very hot when carrying a load....even at max psi and would over time start shedding treads.
Look at a big rig 22.5" tire sometime. They may be a 16 ply rating but are just 5 very heavy plies. Less plies = less flex = less heat running down the highway at interstate speeds.
