I'd like to get some opinions based on experience or logic as to whether snow tires or gravel rally tires would be better in scca rallycross.
I participated in a few events on 245/45 17s and did pretty well, unless it was raining, and it was slick as shit. Everyone kept praising gravel tires for their amazing grip, so eventually I got a set of 15s and some used soft compound hankook's.
First event in them was a grassy field in the rain, and it was like ice skating; even once the grass came up. I've used them a few times afterward and drill was pretty disappointed with the grip. It got me thinking about using some small truck snow tires instead (Dunlop sj6's in mind as they look like a flat track motorcycle tire) in a larger diameter 205/70-15.
Soo logic tells me that a softer sidewall should help grip on loose or slick surfaces, and the blocky tread on snow tires would clear mud as well or better than the gravel tires I've seen. The compound seems like it would be softer, which would increase grip but I don't know how fast they would wear.
Has anyone tried both 15" snow tires and gravel tires? Which did you like better and what downsides were there?
Here's my setup:
evo 8. Mr bilsteins, no sway bars 15" wheels
Location: Washington state,
approx 1/2 events are wet/muddy and include loose soil w/grass and rocky loose soil. There is some hardpack if it's dry and we get through the topsoil.
Anyway..... First round is coming up in a few weeks and I'm itching to get my setup finalized.
