How often to replace tires comes down to three things: tread depth, age, and condition. For most drivers that means every 3–6 years or when tread hits the legal limit — whichever comes first. Here is how to know your exact replacement point, from the team at Mike’s Tires Plano.
Replace by tread depth
Tires are legally worn out at 2/32″ of tread in Texas. Many drivers replace earlier, around 4/32″, for safer wet-weather stopping. Quick check: insert a penny into the tread with Lincoln’s head down — if you can see the top of his head, replace the tire now. The built-in wear bars flush with the tread mean the same thing.
Replace by age
Even with good tread, rubber hardens and cracks over time. Manufacturers generally recommend replacing tires at 6 years and treating 10 years as the hard maximum. You can find the age in the DOT code on the sidewall — the last four digits are the week and year of manufacture (for example “2223” = the 22nd week of 2023).
Replace by condition
Replace immediately — regardless of age or tread — if you see:
- Sidewall cracks, cuts, or bulges
- A puncture in the sidewall (not safely repairable)
- Repeated air loss or a slow leak that will not hold
- Visible cords or uneven, scalloped wear
How Texas heat changes the timeline
Plano’s heat accelerates rubber aging, so a tire that might reach 6 years elsewhere can crack sooner here, especially if parked outside or run under-inflated. Keeping tires at the correct PSI and rotating them on schedule is the cheapest way to reach their full replacement interval.
How often to replace — the short version
Whichever comes first: tread at 2/32″, age at 6 years, or visible damage. If you are between 4/32″ and the limit, start planning so you are not caught driving on bald tires in a summer storm.

Frequently asked questions
How often should I replace my tires?
Whichever comes first: tread worn to 2/32″, age of 6 years, or visible damage like cracks or bulges. Most drivers land in a 3-6 year window.
How do I find the age of my tires?
Read the DOT code on the sidewall — the last four digits are the week and year of manufacture (e.g. “2223” = week 22 of 2023).
Is it OK to replace just two tires?
Yes if the others have healthy, even tread. Put the new pair on the rear axle for stability and match the size and type.
