Putting big wheels and tires on my 2005 Impala

Jeremy’s question:

I’m thinking about putting big wheels and tires on my 2005 Impala. As a professional mechanic, do you see any downsides in doing this?”


Yes, I don’t ever advise anyone to do this. Your Impala was computer designed for the rims and tires that it came with. The suspension system rides best with those size tires. The braking system works best with them. AND the gas mileage will be best using those rims and tires. Putting on Huge rims and tires may look cool, BUT it will adversely effect handling, braking, and gas mileage. If you want fancier looking rims, go right ahead, but I wouldn’t change their size.
