18" vs 20" tires for towing on truck
Anybody have any input on towing between 18" and 20" rims? I'm getting a new 2500 Silverado and the ones I have to pick from all have 20" rims. I will be towing about 9k on the bumper and maybe a fi...

The 18" rims should be able to support a heavy duty tire, while the 20" 'Bling' rims are not real truck tires, and nobody makes a LT Light Truck tire for them.
Good luck,

Pure BS!!!! I have 20" on my 2500 duramax. the 20" tires have a HIGHER load rating than the 18".
While the new '15 HD's may be different, for the HD's up to '14, the 18" tires actually had about 300lbs higher payload than the 20". Not that 300lbs is a huge difference... This was the reason the 20's were not available on the 3500HD SRW.
I have considered switching to the 18's for the tire selection, BUT.... the 20" tire options ARE getting better!!! Part of the issue is the GMT 900 is not the best for allowing slightly bigger tires without a lift.
