| 839879 | 2009-12-15 16:42:00 | I've got 16" wheels on my Nissan Maxima car. They're really nice factory fitted mags, but I'm considering replacing them with 17 or possibly even 18". My questions are... 1) Will a larger size affect the electronic trip computer? 2) Will fuel consumption be affected (for better or worse) ? 3) Will there be any other adverse affects? Ta for any insight. |

| 839883 | 2009-12-15 19:09:00 | You want to make sure the diameter of the tyre is very similar to the factory ones, otherwise the car will either cost a fortune to run or you'll constantly be getting speeding tickets. If you get 17s, or especially 18s you're obviously going to be getting come reasonably low profile tyres - plenty of good things about them but the two downsides are the cost of the tyres and the ride of the car - bit boney. Fuel economy will decrease (more rolling resistance) but not enough that you're likely to notice. I put some Advanti 17s on my Levin, tyre size was 215/40/17. Cost the better part of $700 to wrap some decent rubber round them. |

| 839884 | 2009-12-15 19:11:00 | It should be obvious that if the "rolling diameter" is changed, then the gear ratios will be changed, and the speedometer reading will be inccurate. Edit: same message already given... |

| 839885 | 2009-12-15 19:14:00 | You will be gearing the car up, bit like another gear, the biggest prob might be clearance under the guards. How do the trip meters work on modern jap stuff? obviously not a mechanical counter off the odometer any more. If they are a sensor on the drive train somewhere the overgearing would make it inaccurate (I think) I had 16" wheels from a 32 Ford V8 on my Model A which originally had 19" it accelerated ok but top speed (mile a minute) was down heaps. |

| 839886 | 2009-12-15 20:58:00 | Would the change be of sufficient interest to alter your insurance? I once replaced a 1600 cc motor in an old ute with a similar 1800 cc model and that caused the State some palpitations. :cool: | Scouse (83) | ||
| 839887 | 2009-12-16 07:08:00 | As long as the overall circumference (spelling?) is the same you won't notice any real difference. The trip computer takes a reading from the gearbox in most cases so you need the wheel to be the same size overall for it to stay accurate. Quite often with bigger wheels they will also be wider than stock so may need some suspension work to stop rubbing. Is it stock height? For working out overall circumference with different tires etc use this tool... www.1010tires.com You want to get as close to stock as possible, if you want huge big wheels though you can get you speed sensor re-calibrated |

| 839888 | 2009-12-16 10:13:00 | Just get a thinner tire so you keep the overall size the same | Agent_24 (57) | ||
