I think the answer should be 8000 miles per tyre... because the remaining 2000 miles you use the other tyre... and for 4 wheels the fifth tyre would have run 4*2000 8000 miles... thus the answer should be 8000 miles per tyre...

i think .. at the same time 4 tyres r running so total of their running is
10 000*4 40 000

but 5 tyres r equally used so 40 000/ 5 8000miles

5 tyres run for 10000 miles.
so 1 tyre run for 2000 miles.
according to the question the 5 tyres are equally interchanged. so each tyre is used for 2 times. so 2000+2000 4000miles.

Since 5 tyres used equally to travel 10000miles each tyre is replaced after a minimum distance of 10000/5 which is 2000 miles....In the 10000 miles journey each tyre is used 4 times hence the total distance travelled by each tyre is 4*2000 8000miles
