If you’ve dropped into Grimmer Motors recently for a WOF in Hamilton, you’re probably after some straight-up advice on passing that check without any stress. Well, you’re in the right place. After years of doing WOFs for everyone from folks commuting in from Cambridge, to tradies living out in Te Kowhai, to mums on the morning school run along Ulster Street, we’ve learnt a thing or two about what helps cars breeze through WOFs in good old Waikato conditions.
1. Tyres: Don’t Let Them Be Your Downfall
Keep an Eye on Tread & Pressure
Hamilton roads can be rough on tyres — especially with all the potholes around Rototuna and speed bumps down the Chartwell end. Your tyres cop it every day, so make sure the tread’s at least 1.5mm. Run your fingers over the tread or use your key in a pinch. And don’t forget the pressure — check them at your local servo, or get us to check your tyre tread while you’re getting something else done. Proper tyre pressure means you’ll handle better in those stop-start school runs and save a bit of gas too.
2. Lights: Don’t Drive Blind (Or Leave Other Drivers Guessing)
All About the Beams
Lights get a real workout, whether you’re heading home through the fog on Morrinsville Road in winter or cruising through Frankton on a muggy summer evening. Before your WOF, flick everything on — headlights, indicators, tail and reverse lights. If anything’s out, get them sorted. Don’t wait until a cop pulls you over outside The Base. For more prep tips, see our WOF checklist.
3. Seatbelts: Safety First, Every Time
Give ‘Em a Good Tug and Check the Release
We see all sorts roll through — Suzuki Swifts from Raglan, Honda Fits from Tamahere, or those big Audi Q7s doing the rounds in Hillcrest. Everyone needs working seatbelts. Check they aren’t frayed or sticking, especially if the kids have jammed jellybeans in the buckle again. If they don’t snap back, book in a repair quick smart. We see this all the time and fixing it is usually pretty straightforward.
4. Windscreen & Wipers: Because Visibility is Everything
Cracked Screens & Streaky Wipers = Instant Fail
Hamilton weather can be wild. You’ll get winter fog and frost out Gordonton way, then blazing heat through Glenview. Chips and cracks on windscreens — especially from gravel flicked up out near Ohaupo — need sorting ASAP. Get your screen fixed before the WOF if there’s any damage. And don’t forget the wipers — if you’re getting lines or they’re squeaking across the glass, it’s time for new blades. Top up the wiper fluid too, or check out this quick wiper guide.
5. Brakes: No Stopping, No WOF
Get a Pro to Give Them a Proper Once-Over
Doesn’t matter if you’re driving a Toyota Estima, a Nissan X-Trail, or maybe one of those flash Euro hybrids — brakes are the big one. Queuing in Five Cross Roads traffic gives you a good chance to listen for squeaks or notice a longer pedal travel. If something feels off, get the system checked — pads, discs, and brake fluid, the whole lot. Our techs can do a proper service or inspect the full brake system before your WOF — we work on everything from Mazda Demios to Peugeot 308s to Ssangyongs.
