Ring Programmable Digital Tyre & Tread Depth Gauge RTG7

There’s a pleasant, solid feel to this hefty but compact gauge, which sits at the top of Ring’s new-for-2011 range. As with our top two products, it also incorporates a depth gauge, although this isn’t digital and it can be awkward to read the slider. Where it scores, though, is with its accurate, programmable pressure gauge, which can remember your car’s settings on the backlit display.
