Golf cart tire losing air, bald, or cracking: when we repair and when we replace

Tire calls in the Sandhills come in three flavours: the tire that slowly loses air, the tire with no tread left, and the tire whose sidewalls have cracked from age. They need different answers, and only one of them is usually a patch. Here is how our techs decide, and what each outcome costs.

Type one: the slow leak

This is the most common tire job owners ask us about. A typical example: a 2018 Club Car Precedent with one tire that needs air every week, booked together with a tune-up. Our approach on a slow leak:

1. Inflate to spec and spray it down. Soapy water over the tread, the sidewall, the valve stem and the bead line. A stream of small bubbles marks the spot.
2. Valve stem first. Rubber stems harden and split at the base with age and sun, and they are cheap to replace. On a cart parked outdoors, this is where we find the leak more often than anywhere else.
3. Tread puncture. A screw or nail in the tread of a tire that is otherwise sound can usually be repaired.
4. Bead leak. Corrosion on the rim where the tire seats lets air seep past. We clean the rim seat and reseat the tire, or replace it if the bead is damaged.
5. Sidewall. Any puncture or cut in the sidewall means a new tire. That area flexes too much for a repair to hold.

If the leaking tire turns out to be old and cracked, fixing the leak does not fix the tire, and we will say so.

Type two: the bald tire

Bald tread is simple to diagnose and simple to fix: the tire is replaced. What we add is a look at the wear pattern, because a tire rarely goes bald evenly by accident.

• Both shoulders worn, centre still has tread: the tire has been run low. Most cart tires want 18 to 22 psi, and an underinflated tire flexes, runs hot, and grinds its shoulders, especially on sand.
• Centre worn smooth, shoulders fine: too much pressure.
• One edge gone, the other edge fine: alignment, a worn front end, or a bent spindle. Put a new tire on without fixing that and it wears out the same way.

That check takes a few minutes and saves a second set of tires.

Type three: dry rot

On a cart that only does short trips, tread can outlast the rubber itself. Sun and heat break down the compounds that keep a tire flexible, and NOAA’s Carthage station normals show about 55 days a year at 90°F or above in the Sandhills. The damage shows first as fine cracks on the sidewall, where the rubber is thinnest and bends the most.

A sidewall with that crazed look is not safe, however much tread remains. And a cart that sits for long stretches does not escape it: soft tires on a parked cart take a flat spot and crack faster at the contact patch than tires on a cart that is driven.

Sand and Sandhills carts

Fine Candor sand rides in on the tires everywhere in Moore County. On tires it means faster tread wear on carts that run unpaved community paths or sandy trails, and grit working into the bead on tires that are run soft. For property carts around Carthage that see pasture and sand, a heavier all-terrain tread with a higher ply rating usually lasts longer than a turf tire. The same sand also packs into brake drums, which is one reason we check the brakes whenever the wheels come off.

Picking a tire for how you drive

• Turf tires are wide and smooth so they do not mark grass. Right for a cart that spends its time on a course.
• Street tires have a tighter, flatter tread that runs quieter and wears longer on asphalt. Better for a cart used mostly on neighbourhood roads.
• All-terrain and lifted tires suit lift kits, unpaved ground and property work. They are heavier and cost a little range.

A taller tire raises the effective gearing. Expect a touch more top speed and more strain on the pack and motor on a climb, which can show up as weakness on hills.

What tire work costs

Full figures are on the pricing page. The $50 to $100 service call is usually applied toward the repair.

Four tires or one?

Tires on a cart age together. If three are cracking and one is leaking, buying one now and three next season costs more in visits than doing the set. One tire makes sense when the rest are young and the problem is a single puncture or a single bald tire with a fixable cause.

Pairing tires with other work

Because the wheels are off, we look at the shoes and drums on the same visit and quote brakes alongside tires. If the cart is due for its annual tune-up, which already covers tire pressure and wear plus a brake adjustment, booking tires at the same time is the cheapest way to get both done. See brakes and tires for the full service.

Getting a quote

Send the cart make and year, whether it is lifted, the tire size printed on the sidewall, and a photo of the problem tire. Tires are one of the few jobs we can price accurately before the visit. We fit them at your home across Pinehurst, Southern Pines, Aberdeen, Seven Lakes, Whispering Pines, and Carthage.
