Hillclimb/sprint tyres


poolec7

Recommended Posts

I've asked before, but need to ask again. I'm replacing my CR322 tyres on my ex-academy 7. I compete at Loton in Class 2(Roadgoing specialist production cars).

 

I need some better rubber for hillclimbing, occasional sprinting and road use.................what can you recommend? Tyres are 185/70 R13. I would consider an different size as long as it doesn't involve modifying the wings!

Thanks

Quoting poolec7: 
and road use

 

How much road use?

 

I use supersoft Kumho V70A's. Whilst they would be utterly useless as track day tyre, if you're using them on the road, and don't drive like a lunatic, I'm sure they would last several thousand miles.

If the car is still in academy spec, then Kumho 175/60-13's all around would work well (in soft compound as the 175's are not available in SS)

The ride height will be a little lower.

 

If you were to go for the medium or hard compound tyres on a hillclimb, they would not start to work very well until after the last corner......

We used to get 6000 miles a year from super soft compound Kumho V70A including a full season of sprint/hillclimb dual driven. The road use had negligible impact. I have used soft compound R888 and they are not as good. My current setup means we don't get a whole season out of a set of Kumho but we do have 260bhp and an aggressive geometry setup. ZZR are popular in A24 compound but I've not tried them.

I am an Avon Man, No its not Avon calling but

 

ZZR in A24 are a great sprint and hill climb tyre. I prefer them to the Kumho's and they work well for me. I also tend to leave them on the car for any road work. As Richard posted as long as your sensible on the road most tyres will last.
