can any one tell me if there is any diffirence between these tyres. i have a falken 225/zr 40/18 88y fk421 fitted on my cossie.I need a new tyre but can only find a falken 225/zr40/18 92y fk452 apart from the numbers on the end are they the same tyres thanks.

 

They'll be fine.
It is only the load index.
88 is upto 560kg
92 is upto 630kg

 

Great thanks for that

 

actually i just noticed, 451 / 452.
It might pay to look at the 2 tread patterns first!!!
