FAQ
When to replace tires?
The legal thread depth minimum in most states, including Michigan, is 2/32". At this point, you need to replace immediately as your tires are too worn. Do the good old penny test: stick a penny in the tread with Lincoln's head down. If you can see the top of his head, you're at 2/32" or less. It's safer to replace around 4/32" because that's when tires start losing proper grip in rain. Do the same with a quarter: if you can see the top of Washington's head, the tread is around 4/32" or less. Also replace tires if you see cracks, bulges, or uneven wear patterns.
How much do new tires cost?
The price range for brand-new tires is from $70 to $300+ per tire. It depends on your tire size, vehicle type, and what kind of tires you need. Bigger wheel sizes (19–20" and up) cost more. Premium specialty tires like certain high-end all-weather, performance, run-flat, etc. can also drive the price up substantially. For a common Metro Detroit crossover/SUV size like 225/65R17, budget tires usually run between about $70 and $130 per tire. Mid-range daily drivers are typically $150–$220 per tire, while premium options often cost around $200-$300 per tire. Larger truck and SUV sizes and tougher builds are often $180-$250 each. At Holbrook tire locations, we'll give you fair options across the price range so you can pick what fits your budget and driving needs.
What do tire numbers mean?
Those numbers stamped on your tire sidewall are actually pretty easy to decode. Let's take P 215/55R17 94H as an example.
- P - "Passenger" vehicle (you might also see LT for Light Truck or ST for Special Trailer);
- 215 - tire width (mm);
- 55 - sidewall height (as a % of width; 55% of 215 mm in this case);
- R - radial construction, basically what almost all modern tires are;
- 17 - wheel size (inches);
- 94H at the end shows the load rating (how much weight it can carry) and speed rating (maximum safe speed).
If you don't feel like decoding it, just show us a pic of the sidewall and we'll tell you what you need.
How long do car tires last?
A lot of tires make it about 5-6 years or 40,000-60,000 miles for tread. After 6 years, the tread might look okay but the rubber can dry out and harden. Two identical tires don't wear at the same rate in different conditions. Tread life varies depending on road conditions, air pressure, how often you rotate your tires, alignment/suspension wear, and how the vehicle's loaded or driven (hard braking, fast cornering, towing). In Detroit, potholes and alignment getting knocked out can cut your tire life shorter.
Why are tires so expensive?
It's easy to think tires are just rubber and they shouldn't cost that much. But in reality, advanced material composition and serious design work go into tires. All those rubber compounds, steel belts, and synthetic fibers combine to make sure your tires grip properly in rain, survive potholes, handle your car's weight, and stay stable at highway speeds. Manufacturing tires is complex. There's precision engineering, testing, quality control. Then add shipping costs and tariffs on imported rubber and finished products. At Holbrook tire stores, we give you honest options at fair prices. We offer new, used, different brands, so you can make the call that fits your budget and keeps you safe.
What are tires made of?
A single tire is made up of about 200 different raw materials. The main ingredient, of course, is the part you see – rubber. It's a mix of both natural rubber (from trees) and petroleum-based synthetic rubber. But pure rubber alone would be too soft and wear out way too fast. Carbon black and silica strengthen it. Steel belts give it structure. Fabric cords (typically polyester or nylon) reinforce the sidewalls and help the tire hold its shape under load. Chemical additives help the rubber stay grippy in different temperatures and resist cracking from the sun.
