I running fulla Asurro Speed rated H wet and dry traction A. The dry traction is great. But the wet traction is okay in cornering. Got the for 100 cdn a tire cheaper then Canadian Tire shit tires. I got them at big O tires.
on stock rims i would go with the turbo action lee radials or the firehawk SS20's which is about the same as what you got. I know the SS20 grip like hell because i got a 78 silverado with a small block 400 pushing 380 hp and 448 ft-lbs of torqe to the rear wheels, and it wont even spin the SS20 two lines long on the highway, where as it spun the grandam GT's 8 lines long in first and spun almost another 2 in 2nd. No joke
