Wheel and tire advice

That tire pressure will probably be cut in half. I’m at 11f/13r on my r888r’s for autocross, but it’ll all depend on how they roll and wear.

For the 100 to 200 tw tires, are they all going to be rock chunkers?

My new house is going to have a half mile long gravel driveway. I’m just curious if I should dump my high TW all season tires for something different or if that is going to create other problems for me.

Rock chucking is more about tread that grab small stones and chuck them. The autocross track is the only place I can get 100tw tires hot enough to stick and throw stones. 200tw R1R tires barely pick up stones at the track. The street just keeps the rubber too cold. I have 1/2 mile of gravel driveway too.

Fitting the side panels made a huge difference in the amount of gravel actually making it inside my car. For reference, I'm on 200TW Maxxis Victra VR-1s.

Appreciate all of your kind responses to my post. I had to settle. Wanted Konig's but couldn't get the wheels desired until, maybe, December. Called Luke at Tire Rack. He's building track car and was knowledgeable about the subject. CHAT does not work well for kit cars (my opinion). Paid more than I wanted and didn't get the color desired but they should be fine (it'll be dirty on the track anyway). Here's the order.

That is a nice setup should be well balanced. Those tires heat up very fast so if you decide to do an autocross bring a tire sprayer.

I've been learning so much about tires! But still need to know more...

I've never seen people spraying down tires at autocross. Just using water in a garden sprayer?

Anybody have recommendations on a tire thermometer/pyrometer to purchase?

Why did Jermey wrap his tires? Does it somehow make them last longer?

Wrapping the race tires after use helps keep the solvents in the tire from evaporating, causing the tire to harden up.

I don't remember seeing what bolt pattern you are using. If 4x100, Goodwin Racing usually carrys a good stock of Konigs and good pricing. Yes they're a Miata based site but it doesnt mean the wheels dont fit.
Bought my Dial-In's from them and tires from Tire Rack.

@JBINTX all 4 corners right? Also can you say more about stud size/thread pitch for the studs, and the thread pitch of the lug nuts you used?
Yes, all four corners have spacers and same size tires and wheels.
You will need to trim of the studs a little so they do not protrude beyond the spacer. A grinder and a cutoff wheel makes quick work of it. Be careful to not damage the threads. Not ideal, but neither are spacers.......
Pictures show the part numbers and threads. I am not sure all Cobalts are the same stud sizes. Mine is 2009 tc for those who read this later.

Thank you VERY much, this is awesome. Really appreciate it.

Don't believe a hardened nut will gain much as a thread chaser, but it may last a few more studs than a standard nut. Personally, I would have a set of nuts for one corner (4 or 5), put them all on the studs before trimming. That set should last through all 4 corners before getting too galled up, standard or hardened.
