Services
What we work on
- 01
Tire inspections
A full diagnostic pass that finds the actual cause of a noise, light, or feeling in the car before any repair is quoted.
- 02
Brakes
Pads, rotors, and lines inspected and replaced, with the old parts set aside so you can see exactly what was worn.
- 03
Oil & fluids
Oil, coolant, transmission and brake fluid checked and changed on schedule to keep smaller problems from becoming engine work.
- 04
Engine repair
From a rough idle to a timing issue, we trace the fault to its source and walk you through the repair before we start.
- 05
AC service
Recharge, leak checks, and component repair to get cold air back before summer drives through the Inland North County heat.
- 06
Smog & inspection
Testing and pre-repair diagnosis so you know what needs attention before the inspection instead of after a failed result.

Show, then tell
We show you the worn part before we recommend replacing it.
Diagnose before you decide
You get a diagnosis first, and you approve the repair before work starts.
No guess-and-replace
Parts get replaced because testing points to them, not because it's a common failure.
Know your tire size
It's printed on the sidewall — or just give the year, make and model.
Get the out-the-door price
Tires, mounting, balancing and disposal, added up before anything comes off the car.
The work gets done
What was agreed, at the price that was agreed.
Drive off knowing the basics
Ask what pressure to run and when they should be rotated. That's part of the visit, not an extra.
Before you buy tires
Four things worth knowing — whoever you buy from
Ask these of anyone quoting your tires — us included.
Compare out-the-door prices
A low price per tire can grow at the counter. Ask for the total with mounting, balancing and disposal.
Check the date code
Every tire carries its manufacture date on the sidewall. It's a fair thing to look at before they go on.
Used tires need a closer look
Tread depth, age and any patches matter. Ask to see the tire before it goes on the car.
Ask about alignment
Uneven wear on the old tires can point to alignment. It's worth asking about before new ones go on.
We put you under the lift, not just the invoice
Power Tires runs on a simple habit: show the customer the part before we replace it. A pad worn to the backing plate, a belt cracked along the ridges, a battery that's stopped holding a charge — you see it, then you decide. San Marcos cars deal with the same climbing grades and stop-and-go through Vista and Escondido, and that wear shows up in predictable places. We check those places first, explain what we find in plain terms, and only do the work you approve.

Questions
How do you decide what actually needs fixing?
We run diagnostics first — computer codes plus a physical check of the related parts — and match the repair to what we actually find. If a part is borderline, we'll say so instead of replacing it on a guess.
Can I see what's wrong with my car?
Yes. We keep worn or failed parts aside so you can see the wear yourself, whether it's a brake pad, a belt, or a battery that's stopped holding charge. Seeing it is part of how we explain the quote.
How does scheduling work if I need it looked at soon?
Call and describe what the car's doing — noise, light, feel — and we'll get you on the books accordingly. Anything that sounds like a safety issue, like brakes, gets prioritized in how we schedule the day.
