Which tires? NT555, Proxes 888, Invo, Pilots ??
 

What tires are you guys finding to give the best of all worlds on the street? Not a track car, very little if any autox, just spirited fun .. 68 Camaro, mini tubs, rolled lips and Ridetech triangulated 4 link/coil overs.
Looks like the most popular and most available are the NT555, Proxes 888, Invo, Pilot Super Sports and Sport Cup.. wanting (hoping & dreaming) I can get 345-30-19's to fit with 19x11.5's

Don't put a 345 on a 11.5 wheel just to say you have 345s.

Regular street car doing regular street car things I would run Continental Extreme Contact Sports.

Which Tires
 

I run the Continentals on the front of my
Pantera as it was the only good street tire
I could find with a low profile. They work well
I usually run Dot road race tires but have been
running street tires lately since we have little
track or autocross days lately

It's looking more realistically like 325/30-19's

The Michelin Pilot Sport 4S is a fantastic all-around tire. It has not only excellent dry traction, it is hands down the best tire we've ever run in the rain, as in light years better than even the earlier PS and PSS versions.

When Tire Rack's comment on what could be improved is, "Nothing", that says a lot. https://www.tirerack.com/tires/tests...y.jsp?ttid=223

I second the PS4's. Just did a set on a customer car. First, they road force balanced at 1, 2, 4, and 4 lbs., that's phenomenal. I've driven it a few hundred miles, and it's an unbelievably grippy tire that rides very well. Wet weather traction is second to none.

I concur. I have had a bunch and currently have PSS on 2 cars, along with 4S's on a car, and keep a couple sets of Sport Cups around. I am sold on being a Michelin ummm..,. guy.

I admit I have R888's on the Chevelle because of size requirements, but man they are paint killers.

345's on a 12" ?
325's on 11" or 12" ?

I would go 325 on a 12 if you have room for a 12" wheel. More choice in 325 as well. 305s for an 11" wheel.

I can't imagine I wouldn't have room for 12's with the DSE mini tub kit, notched frame rail, narrowed rear end, rolled fender lips and Ridetechs triangulated 4 link..
I get the rear back from Moser on Friday so I'll do a lot of measuring and let you know. Thanks

Damnitman, even the 325's are giving me fits on fitting.. might have to drop down to a 315/40-18
I don't want to go to a real low pro tire like a 315/30-18

What if I told you that a 315/30-18 and a 305/30-19 have the same sidewall height?

You have 14.5" You need .75" to the inside and .25" on the outside assuming you are running some type of link suspension. Those are your minimum clearance numbers. You can run the outside tight as most 67/68 camaros don't travel enough to actually tuck into the fender much anyways.

So your maximum section width is 13.5"

325/30-19 is 13" wide on a 11.5.....put it on a 12 and you get 13.25"ish.

I'm running the Ridetech triangulated 4 link & coil overs, mini tubs, rolled lips. if .75 and .25 are good clearances then the 325's might just work.
I don't like the low profile of the 315/30-18 or the 305/30-19
I do appreciate your input, Thank you
