To provide a tire-fitted suspension device, wherein, even when fitted with a tire having a sufficiently reduced weight, a specific vibration from the tire is prevented from transmitting to a vehicle body through a rod of a front side shock absorber.SOLUTION: An elastic body 14c of a front side mount 14 has a kinetic spring constant smaller than a kinetic spring constant of an elastic body of a first front side bush 13, and a tire T satisfies the following formula: W/[{(R/2)-(r/2)}×3.14×H]≤1.8×10, where weight is W (kg), sectional width is H (mm), tire outer diameter is R (mm), and application rim diameter is r (mm).SELECTED DRAWING: Figure 1
【課題】軽量化が充分に図られたタイヤを装着しても、タイヤからの特定の振動が、フロント側ショックアブソーバのロッドを介して車体に伝達するのを抑制する。【解決手段】フロント側マウント14の弾性体14cの動的ばね定数は、第1フロント側ブッシュ13の弾性体の動的ばね定数より小さく、タイヤTは、重量をW(kg)、断面幅をH(mm)、タイヤ外径をR(mm)、および適用リム径をr(mm)としたときに、下記式を満たす。W/[{(R/2)2−(r/2)2}×3.14×H]≦1.8×10−7。【選択図】図1
