Workshop guides to help new tyre fitters work safely and accurately.
Before you start, check your make, model and year, then check your socket size and tyre size.
Before the wheel goes back on, make sure you check the torque value. If you are at all unsure you should check, don't rely on a best guess.
Search wheel nut torque specs →Why Torque Matters
The dangers of under- and over-torquing wheel nuts, and how to get it right step by step with a calibrated torque wrench.
Reading a Torque Specification
Nm vs ft-lb, dry vs lubricated threads, and why the number on its own isn't the whole spec.
Matching Tyre Width to Rim Width
Every tyre has an approved rim width range. Fit it outside that range and you change the tyre's handling, wear and safety margin, even if it bolts on fine.
The Wheel Nut Tightening Sequence Explained
Why the star pattern matters and the correct sequence for 4, 5 and 6-stud wheels.
Common Mistakes New Fitters Make
The four errors behind most wheel-related comebacks, and how to avoid every one of them.
Trusting Your Source: The Data Hierarchy
Not every torque spec carries the same confidence. How TorqSpec scores every spec from 100% down to an 87.5% provisional floor, what each tier means, and why it matters on the hoist.
Why Wheel Balancing Matters
An unbalanced wheel shakes the car, cups the tyre and wears the suspension. Why balance matters, and why a new balance isn't a one-off job.
Is It Repairable? The T-Zone and Repair Limits
The T-zone, the 6mm and 45 degree repair limits, and the maximum repair count. The first call on whether a puncture can be fixed at all.
When a Tyre Is Scrap
A puncture can sit perfectly in the T-zone and the tyre can still belong in the bin. The casing calls that decide, not the hole.
