I always changed the tyres separately as I went thru rear tyres in 3-4000 miles max, less (MUCH LESS) if I was taking it up the strip! Any way front tyre was usually in the air most of the time! LOL! Wheelies AND wheel spin at the same time was always an interesting experiance on a very light 2 stroke! <<WEG>>

I love the smell of molten rubber in the morning!!
