If you don't want to trust your speedo reading under, then just look at your beloved GPS instead Why bother with changing tyres at all? As they wear out the speedo will be affected again by a few %! lol |

OK done some calculating and here is what I got. 215/45/17s: Rolling Radius - 196.3442cm Total Diameter - 62.53cm Sidewall Height - 9.675cm With the 215/55/17s: Rolling Radius - 209.8462cm Total Diameter - 66.83cm Sidewall Height - 11.825cm So for every 1KM, the stock size gets 510.2 rotations where the 215/55/17s get only 476.5 rotations. So the stock tires @ 100KPH Rotate at 510200 rotations and the 55s get 476500 rotations respectively. That means with the larger tires, you will get approx 6.44% more distance by using the larger tires, which would then put your speedo out again, to be too slow to the actual speed and net you tickets/speed camera fines etc. Is it really worth it? Someone feel free to correct me if I'm wrong, my form 6 math (Level 2 NCEA) is quite limited haha |
