Porsche Tires

Sales, Service & Installation

While servicing clients’ cars, technicians take notice of the condition of the tires. “When your tires are worn out and you only need two,” says David, “I always suggest matching them with the tires that are good.” (Usually the rear tires wear out more quickly…) Why match the tires?

David says it would be like wearing two types of shoes, a tennis shoe on one foot and a dress shoe on the other foot. They’ll work out but not as well as a matching pair. It’s the same with tires; each manufacturers’ tires handle differently, mostly because of varying tread patterns. “Due to our new shop’s much larger space — we moved Jan. 2016 — we’re now able to carry a good selection of brands-new Porsche tires,” says David. “We can also special-order tires and they’re shipped to us the next day for in-house installation.”

If you need all four tires replaced there are a number of choices in different prices ranges specific to each individual car. “I’ll guide you along,” says David, “and I do caution against using non-name-brand tires for your Porsche. We’ll discuss your driving style and put the right ‘shoes’ under your auto. We’ll also get the car aligned to ensure that you get the maximum life out of those tires.”

Tire Pressure Monitor System

Great Consumer-Friendly Technology

If you drive a late-model Porsche, you probably have what’s called a tire pressure monitoring system (TPMS) installed. TPMS is an electronic system inside the tire that monitors the air pressure in your tires.

TPMS takes the guesswork out of accurate tire pressure. It automatically lets you know when pressure is low, which keeps you safer and protects your tires from damage. Obtaining optimum fuel milage is another benefit to keeping your tires properly inflated.

If your tires are under- or over-inflated, the TPMS activates a warning light on your dashboard. Whenever you see the light on ― steady or flashing ― it means you need to have your tire pressure checked.

With any of these instances, feel free to stop by Modderman Service for a free tire pressure check. If you’re traveling, get to a gas station as soon as possible, and add air to your tires. If you need to change a tire because of a flat, don’t be alarmed when you see the TPMS light illuminate or flash after you install the spare.

It’s just the system’s way of letting you know it can’t find a TPMS unit in the spare tire. Bad sensor or bad battery? If you see warning “system not working,” it could indicate a bad sensor or a sensor’s battery is faulty.

“We’ll scan the diagnostic link and read the battery life of each sensor,” says David. “Sensors tend to last between five and seven years, and then need to be replaced.” Whatever the issue, David assures the solution is a quick fix.

You can check out the TPMS display at the front counter.

Tire Safety Tips

Purchase Tires Before They’ve Become Worn

If you ever poke around a salvage yard, take a look at the cars that have been in a crash. What you may find is the majority of these vehicles have bald tires. You can drive smarter by replacing tires before they’re worn to the wear bar. With newer Porsches, you may need to replace tires every 9,000 miles.

Did you know you can improve your gas mileage by 0.6% on average—up to 3% in some cases—by keeping your tires inflated to the proper pressure? Under-inflated tires can lower gas mileage by about 0.2% for every 1 psi drop in the average pressure of all tires. Properly inflated tires are safer and last longer. Not sure what the correct tire pressure is for your car’s tires? Just give us a call and we’ll be happy to help you out: (650) 967-3213.  Better yet, just stop by the shop so we can also evaluate your tires’ condition.

Interesting fact: You want to check your tires’ pressure at least once a month. And it’s best to do so in the morning when the pressures are cool and stabilized. Wondering when to rotate your tires? “We suggest rotating tires every 5,000-7,000 miles,” says David. “People don’t often think ‘tire maintenance’ though it’s an important minor service that can help your tires to wear evenly and at the same time.”

If you’re wondering if your tires are safe for your next road trip,
simply stop by our shop for a quick “look-see.”


Using The Best Tire, Wheel,
Balancing & Mounting Equipment

For The Best Cars, “We’re Talking Porsche Automobiles!”

Modderman Service has never believed in taking short cuts to properly service and repair customers’ vehicles. That same philosophy — no “short cuts” — applies to their ongoing investment of high-quality tools and equipment. David considers keeping up with the latest automotive technology a “must-do,” and that includes tire, wheel balancing, and mounting equipment.

Their state-of-the-art Snap-on Tire and Wheel Balancer not only solves wheel balance problems, but also “road tests” the tire/wheel assembly to eliminate virtually every variable causing vibration in relation to the tire and rim.

Snap-on Tire Mounting System: This equipment was designed to ensure that no metal touches the wheel faces during the mounting and dismounting procedure, which highly reduces the chance of getting dings and scratches in your wheels, or damaging tires. You probably value your Porsche wheels, and we want them to remain pristine when you leave Modderman Service.

Corghi Tire Spreader: When inspecting or repairing your tires, it can be really difficult to get the tire spread far enough to get to the inside of the tire. The Gorghi equipment has been the perfect choice for Modderman’s technicians. The spreader is easy to use and it helps to make inspecting and repairing tires a fairly quick procedure. You’ll be back on the road before you know it!
