Was going to get some new ones, I'll be looking at medium to hard as the boat weights 1450ish kg, none of the second hand ones I've seen or asked the tyre dudes at the track about are the size I'm after "245ish/40ish 17" but no bigger(8" rim)
On the tyres hardness, I'm using my totally uneducated guess work, if I've got this wrong feel free to tell me I've got it all wrong.
I'm hoping for them to last a while to, last time I used soft compound the tyres lasted 2 sessions.
I'll only be using them for sprints, so 1 or 2 warm up laps then 2 hot ones.
Thanks.
