| Speed Ratings |
| |
| Speed Ratings are one of the aspects to consider on any type of vehicle when purchasing tyres. As most roads in Australia have a maximum speed limit of 110Klms/H most speed ratings found on tyres are well above what is required. Laws vary state to state, but generally if a tyre has a speed rating above 110Klms/H n trucks or trailers or, 160Klm/s/H on other vehicles it is considered legal. High Speed Ratings should definitely be fitted to weekend track vehicles, or vehicle that regualrly drive at high speeds in private facilities.
The ZR or VR is also sometimes found in tyre sizes, these were originally placed into the sizes to show they were manufactured to speciifications that allow safe use at up to 240Klms/H, VR rated tyres aren't used anymore with most manufacturers now using ZR as the standard specification. It is worth noting that while ZR is found in the tyre size it is actually not the specific speed rating, please see below to find out more about the location of your speed rating. |
