RV Tire Safety
with RV tire expert Roger Marble
When people shop for a car or truck very few pay attention to the tires other than to decide if they “look” good.
A few years the ago “stylists” decided to start moving to ever-larger wheel diameters. In a few cases, there was a reason to move from 15″ to 16″ due to increased brake rotor diameter. This increase does not apply to standard cars or pickup trucks.
If you look at the clearance between the brakes and wheel sometimes that are many inches. This tells you that the reason for your “big wheels” is most likely just a styling gimmick.
The larger wheels are more expensive and the larger wheel diameter requires a significant increase in tire manufacturing equipment in the tire plants to make the 18″, 19″, 20″ and larger tires.
My Chevy 3500 and 4500 trucks work just fine with 16″ tires, so other than styling looks I have no idea why people think they would need anything larger on their 1/2- to 1-ton TV.
There is a definite downside to having a vehicle with larger than 16″ diameter wheels: that is a higher cost and fewer choices when it comes to buying replacement rubber.
If you do a little research you will discover the more limited selection. Your tow vehicle has a job to do, so it is probably to your advantage to not get the truck because it looks “hot,” as you may end up paying the price for excesses of the “stylists”.
Just one man’s opinion.
