Mazda MX-5 Tyre Rubbing and Guard Repair in Perth
Roy originally brought his Mazda MX-5 to AutoFX WA because the rear tyres needed more clearance.
We rolled the rear guards and pumped them outward by approximately 25mm. This gave Roy the additional room needed for his wheel and tyre setup.
Roy later returned after developing a separate problem at the front of the car. The front tyre had caught the guard lip and pulled at the edge of the panel.
Why the Front Tyre Caught the Guard
A wheel and tyre may appear to clear the guard while the car is sitting still. However, the suspension moves much further during normal driving.
The tyre moves upward when the car travels over bumps, turns through a corner or carries additional weight. If there is not enough clearance, the tyre can rub against the guard.
In Roy’s case, the tyre did more than lightly rub. It caught the front guard lip and started pulling it out of shape.
Once a tyre catches the lip, damage can happen quickly. The tyre can distort the guard, damage the paint or cut into the tyre itself.
The Rear Guards Needed a 25mm Pump
The rear of Roy’s MX-5 needed more than a normal guard roll.
Guard rolling folds or reshapes the inner lip to provide additional tyre clearance. Guard pumping goes further by gradually moving the outer section of the guard outward.
We pumped the rear guards by approximately 25mm. That is a substantial change on a small vehicle such as an MX-5.
The work needed to create enough clearance while keeping the shape of the rear guards looking as natural as possible.
Finding the Actual Contact Point
Not every tyre clearance problem needs the same solution.
Wheel width, tyre size, offset, suspension height and wheel alignment can all affect where the tyre contacts the vehicle.
This is why I prefer to inspect the actual rubbing point before deciding how much guard rolling or pumping is required.
In this case, the rear guards required the larger pump. The front became a separate repair after the tyre caught the guard lip.
Checking Clearance After Wheel or Suspension Changes
Roy’s MX-5 is a good example of why tyre clearance should be checked after fitting wider wheels, different tyres or lowered suspension.
A small amount of clearance in the workshop may not be enough once the suspension is moving on the road.
Look for fresh marks on the tyres, polished areas inside the guards or damage around the guard lip. These can be early signs that the tyre is making contact.
Addressing the problem early may prevent more serious tyre, paint and panel damage.
Mazda MX-5 Guard Rolling in Perth
AutoFX WA provides guard rolling and guard pumping from our O’Connor workshop in Perth.
Every vehicle is assessed individually. We consider the wheel and tyre setup, suspension, existing paint condition, previous body repairs and the amount of clearance required.
Guard rolling involves moving both metal and paint from their original position. Results and risks can vary between vehicles, especially when a panel has been repaired or repainted previously.
Contact AutoFX WA if your Mazda MX-5 is rubbing its tyres or needs additional wheel clearance.
