What is load range XL vs E?
XL is a heavier-duty version of a passenger tire, which is supposed to ride more smoothly, and E rated is for Light Truck tires, which can be a little stiffer, but the load capacity is increased and the speed rating is decreased. I have 275/65R18 E rated tires and they ride just fine.
Are E rated tires 10 ply?
E-Rated Tires: Wrap Up To conclude load rating E means that it's a 10-ply tire that can handle up anywhere between 60PSI to 85PSI when carrying the max load. To know the maximum weight capacity of a tire, you'll need to check the load index. The higher the number, the more weight it can hold up.
Is a higher load rating better?
The load rating can be located on the sidewall of all tyres and is represented by a numerical value. The higher the load rating number, the stronger the tyre. Tyres with a higher load rating can take a greater amount of air pressure, which means they can also carry heavier loads.
Should I get H or V rated tires?
