Well, I'll be completing my first year running in SCCA H-Stock this Sunday. I had a problem finding anything other than 205-50-15's that will work with the 15X
6 wheels and that meet the stock requirements. For most of the year I ran AVON tires in dry conditions, while using Bridgestones for wet days and "street tire" classes.
The Avon "tyres" have a very strong side wall and are very sticky. I feel their draw back is the 23# they weigh. This is caused by the steel reinforced construction but puts them at 5# more than KUHMO and some other good brands. But, they are a good buy if purchased on close-out from Tire Rack.
I've settled on the Tire Rack Sport Edition D4 $59 each (closeout) +
50mm offset,
14.5 lbs for my rim of choice for H-Stock. Other
new wheels I've located run $1000+ for a set of four.
Way out of my price range for this class.
I'm planning to begin the 2008 season on KUHMO's to reduce the weight by 5# per wheel.
My off-track tires are KUHMO sport 205x50x15's mounted on light-weight 7" wide rims. I wouldn't recommend running any wider tire on a Fit 15" wheel.
