Dear Dr Naveed, Including me and all valuable pakwheels members here have been recommending you to use donut tyre if you want to have it to use for emergency, again Pak Suzuki has provided repair kit aswell, you can use it on your existing tires. This donut tyre is meant to be used when in case your tire gets totally busted( Phat Jae) maybe by hitting some sharp object, its obvious you cant repair it with that kit.
If your tire is busted, how would you drive your car to home or any repair spot ? Thats what donut tyre is meant to be used for, if you use donut tyre it wont harm your suspension anything if driven under moderate speed of 40-50 and it should be in good condition.
Its pretty obvious why PakSuzuki would recommend you to use donut tire !
They have a point that they have provided repair kit thats enough for you, but the point is we dont have ideal conditions of our roads, there is always a possibly that tire might get burst if you are unlucky. Then only you use donut tyre.
Exactly, its pretty universal to cars.
