thanks pro ten yup i forgot to rotate the tyres i was having to much fun to think about that

but when i got home i took all the tyres off to store them in glad wraps and did a comparison in sizes and the fronts came off pretty much the same so were the rears (left to right) although i need a digital vernier to be more accurate
