Wheel Repair and Powder Coating for Somerville Drivers: A Practical Guide

The number one cause of wheel damage in Somerville is parallel parking. Resident permit streets around Davis Square, Union Square, Spring Hill and Winter Hill are often lined bumper to bumper, so you squeeze into whatever gap you find. Many of those curbs are granite, and granite does not forgive. A few inches of misjudged distance on the passenger side is all it takes to grind the lip of an alloy wheel and break through the factory finish.

Street sweeping days and snow emergency rules add to it. Moving the car more often means more parking maneuvers, and every one of them is another chance to touch the curb. Drivers who park in the same tight spot every night often find the same wheel takes most of the damage, because it is always the one closest to the curb.

Potholes are the other half of the story. Freeze and thaw cycles break up pavement every late winter, and busy routes like McGrath Highway, Somerville Avenue, Highland Avenue and the approaches to I-93 tend to open up first. Utility work, construction plates and patched trenches create sharp edges that low profile tires do not cushion well. A hard hit can bend a rim or knock it out of round enough that you feel it at highway speed.

Massachusetts treats its roads heavily through the winter, and that salt and brine film sticks to wheels, lug seats and brake parts. On a factory painted or clear coated wheel, trouble usually starts at a chip, often from a curb strike or a tire machine. Moisture and salt get under the edge of the chip, and the finish begins to lift from underneath.

That is the white, bubbled corrosion you see creeping under the clear coat on a lot of older wheels around the city. Brake dust makes it worse. City driving means constant braking at lights and crosswalks, and the iron particles in brake dust hold moisture against the surface and bake onto the inner barrel.

Once corrosion has lifted the finish, no cleaner will reverse it. The wheel has to be stripped back to clean metal and refinished. Powder coat is one of the most durable ways to do that, because it is thicker and harder than typical spray paint and holds up better to salt and dust.

Rinse your wheels during salt season, not only in spring. Many city drivers skip winter washes entirely, and that is exactly when corrosion gets its start. A self serve wash every week or two, aimed into the barrel and behind the spokes, removes most of the salt before it can work into chips.

Use a pH balanced wheel cleaner and a soft brush. Strong acid cleaners and stiff brushes slowly wear down any finish, powder coat included. Check tire pressure monthly. A properly inflated tire protects the rim when you cannot avoid a pothole, and low pressure is one of the most common reasons a wheel bends instead of rolling through.

When you parallel park, use your passenger side mirror tilted down if your car allows it, or simply give the curb a few extra inches. Most of the curb rash we repair happens at walking speed, one small scrape at a time.

It helps to know which kind of damage you are dealing with. Curb rash, scratches, faded paint and surface corrosion are cosmetic. They look bad and corrosion keeps spreading, but the wheel is still sound and can be repaired and refinished.

A vibration that started right after a pothole, a tire that keeps losing air, or a visible crack on the inner barrel are more serious. Those can point to a bent or cracked wheel. Many bent alloy wheels can be straightened, and some cracked aluminum wheels can be welded when the crack is in a safe spot. Some cannot, and in that case replacing the wheel is the honest answer. We would rather tell you that than coat over a wheel that should not go back on the road.

Two clear photos, one of the face and one of the inner barrel, usually tell us which category your wheel falls into.

The tire comes off first, along with the TPMS sensor and any wheel weights, because sensors cannot go through the curing oven. The wheel is then stripped and media blasted to bare metal so the new finish bonds to clean aluminum instead of old paint and corrosion.

Curb rash and gouges are repaired before any coating goes on. Cast wheels are usually preheated so trapped gases can escape, a step called outgassing, which keeps the finish from bubbling. The powder is applied electrostatically and cured in an oven at around 400°F, where it flows into a hard, even shell.

After curing, the tire is remounted, the sensor reinstalled and the wheel balanced. Colors come from the Prismatic Powders library, which covers thousands of colors and finishes, and we can custom match a color too. If the finish is not right, we redo it at no cost.

Across New England, most shops typically charge somewhere around $100 to $200 per wheel for standard powder coating on a common size. Curb rash repair, straightening, crack welding, larger wheels, two tone finishes and custom colors can each add to that, so the range for a full set varies quite a bit.

A photo gets you a free ballpark price, which is usually enough to decide whether the job makes sense. The final price is set once the wheels are at the shop and we can see everything up close, including damage on the inner barrel that photos often miss. We take credit card, cash, check, Zelle and bank transfer.

All repair and coating work happens at our shop at 100 Minnesota Ave in Warwick, RI. From Somerville that is roughly 60 to 65 miles, usually somewhere around an hour to an hour and a half via I-93 South and I-95 South, and longer at rush hour. Shop hours are Monday to Friday, 8:00 AM to 4:30 PM.

Because of the distance, most Somerville customers plan ahead. A common approach is to bring the wheels and tires off the car, which works well if you have a spare set or winter wheels to drive on in the meantime. Others bring the car down and arrange a ride. While you are planning the trip, it can make sense to bring other metal pieces too, like motorcycle parts, a patio set or iron railings, since we coat those as well.
