The spare Tyre of my 40,000 km run Honda City is unused and brand new since I bought my car 4 years ago. I want to use this spare Tyre and an other brand new Tyre 2019 make in the front. All tyres are Eurosport. Kindly comment is it ok to do so?
no problm but to be at the safer sidekeep it at the rear
keep using it as spare thats' what @hash4u mean
9 year old spare Yokohama ASPEC as good as new (discontinued series) is with me in trunk. randomly once a quarter it is removed & refitted from rim, specially when heading out over long route.
