What is the required clearance distance between the front of the tyre to the middle of the swingarm (the weld line is the closest point) The tyre must "grow" due to heat and centrifical force? Tony |

I would say that the minimum clearance would be just a few millimeters when the tire is new. The tire only wears, and in general, few of us get up to the speeds where tires grow. But thats my guess. |

German TÜV normally wants min 5mm between all moving and fix parts. Here`s a tire calculator (based on official calculation formulas from ETRTO - European Tire and Rim Technical Organization) on a german site: http://www.vw-page.at/pages/trickkiste_ ... hp#rolldyn Enter tire width, ratio and rim size. The results shown are: rolling circumference (circumferential length of the tire at one spin of the wheel, while impacted by wheel load of the vehicle) static rolling radius (distance from wheel center to road surface while standing. Note the tire is not a perfect circle when standing on the ground) dynamic running radius (calculated diameter incl. growth due to centrifugal force at 60km/h) suspension comfort index tire volume G. |
