TIRE MATH! Does it add up? Are all tires created equal? The answer is NO! It's not just brands you need to worry about. Tires are rated for different treadwear, traction, and tempature.
When you are selecting tires a BIG factor is PRICE! You may be able to find two different versions of the EXACT same tires. Option A may only be $35 per tire and Option B could be $60 per tire. But, to math it out... Option A Tire may only be rated for 30,000 miles, while Option B Tire may be rated for 70,000 miles. Yes, Option A might be cheaper right now, but Option B will save you money in the long run.
