Tire size and towing ability
Hi everyone, I'm a recent Chevy owner--'04 2500HD Crew Cab 4x4, 6.0L, 4.10's--and I have a couple questions so far...
First off, why do they put these little dinky tires on such a big truck??? Well, I want to increase my tire size, but I don't want a huge decrease in towing ability. I've been told I could fit 33's on it, if I crank the torsion bars, or rekey it, and trim the plastic on the front bumper a little, or I could fit 32's on it without any modifications. My real question is how much power loss regarding towing ability will I notice if I go to 33's?
Would there be a big difference in power between the 32's & 33's?
How much would replacing the exhaust system help overcome this power loss?
We tow a 7500lb travel trailer, and will eventually tow the CJ7.
