Different Tire Size
« on: January 29, 2013, 03:49:24 AM »
I'm planning to replace my tires on my Super 8.  I currently have 100/80/14 front and 120/80/14 rear. I'm planning on a 110/70/14 and 130/70/14.   How would this affect the scoot's performance? Acceleration, speed, handling, comfort?   I've seen these tire sizes on some Super 8s and they look just grrreat!!



Here's an example of that rear tire....

I put an over-sized rear tire on my people and I love it. It's wider and taller. Went from a 100/80 to a 120/80; 20mm wider and 16mm taller. I don't remember any significant difference in acceleration or top speed. Handling did improve though. Much more stable too(comfort). I suspect it will be even better if I can ever find an over-sized front that will fit. I found that I get a smoother ride with a little less pressure than the stock rear tire called for.

110/70 is 10mm wider and 3mm shorter. 130/70 is 10mm wider and 5mm shorter. No significant difference in height, or weight for that matter. I doubt you'll notice much, if any, difference in acceleration or top speed. If anything you might gain acceleration and lose top speed... Nothing major. Either way you could probably offset that with slightly heavier rollers. IMO wider is better especially with the tiny tires they put on these scooters. I think you got a good plan V  ;D

Thank you for the quick replies guys.... I'll do it.... I wonder if a bigger than 130 rear tire will fit... The most I've seen is 130....

Cut a piece of cardboard 140mm wide and see if it will clear... Of course you might have to take the wheel off

Of the tyre is taller or shorter than stock then i will affect the speedo reading (maybe not the actual speed, but def the speedo reading).

Depending on the difference in height tho you may not notice it much if the difference is small. I had to deduct 10% on my car speedo after swapping to real low profile tyres a while ago when i lowered the front end.
Chaos is my co-pilot.

If you change the rolling circumference of your wheels and tires, the speedometer no longer reads correctly, and your odometer will also gradually become inaccurate. Assume for example that you bought a car brand new and changed the wheels and tires on day one from 185/65/14 to 205/50/15, that makes your speedometer over read. Consequently, the registered odometer reading will also differ. So for example, when you get to 10,000km of driving (in the real world), your odometer will actually read more. It won't be a huge difference but it is one of the reasons why most car dealers have a disclaimer on their secondhand vehicles telling you that they won't guarantee the displayed mileage.
It's worth pointing out that without exception, all motorbike speedometers are designed to inflate the ego of the rider by at least 5%. In some cases, they are are much as 10% optimistic. ie. the speedometer on a motorbike will always over-read. 100mph? Not likely - you're actually doing closer to 90mph.
